Rollins Emerson was early dry bean researcher in Nebraska

Bob Harveson – University of Nebraska – Lincoln Extension Plant Pathologist
& Carlos Urrea – University of Nebraska – Lincoln Dry Bean Breeder

The world renowned geneticist, Rollins Emerson, should be recognized as the catalyst for beginning the dry bean industry in Nebraska. However, he is little known in his home state.

Rollins Adams Emerson was born in upstate New York, but his family moved to Kearney when he was seven to homestead new farmland on the prairies. After completing high school, he enrolled in the Agricultural College at University of Nebraska, graduating in 1895 before joining the department as assistant horticulturalist. After a two-year stint as an assistant editor with the USDA Office of Experiment Stations in Washington DC, he returned to Nebraska in 1899 to accept a position with the Nebraska Experiment Station as horticulturalist, professor and head of the Horticulture Department.

Emerson Initiates Dry Bean Genetic Studies

Emerson then began a career of research in genetics, concentrating first on the common bean, thus becoming one of the early dry bean researchers in the US. In fact this work occurred more than 20 years before the start of the dry bean industry in Nebraska. His first experiments resulted in a paper published in 1902 entitled: “Preliminary Account of Variation in Bean Hybrids” with a second paper on bean hybrids appearing in 1904. He also published a number of later papers on inheritance of seed color, seed size, and other character traits of the common bean.

2016 International Year of the Pulse

2016 International Year of the PulseCelebrating 2016 the Year of the Pulse and the impact of dry bean production in Nebraska. The state ranks first in production of great northerns and fourth in overall US dry bean production. See related articles.

He was one of the first American scientists to understand and embrace the ideas of Gregor Mendel (also referred to as Mendelian genetics). These principles state that certain genetic traits are inherited or passed on to progeny from their parents. Mendel discovered and noted these characteristics experiments with garden peas. Emerson’s early landmark papers on dry bean breeding illustrated his firm grasp of the newly discovered laws of inheritance and highlighted his interest in testing the validity of Mendel’s laws using the genus Phaseolus (common bean) as his experimental model.

Cornell Years

Emerson took leave from the University of Nebraska in 1910-1911 to pursue a Ph.D. at Harvard. After obtaining the degree in 1912, he returned to Lincoln, but accepted an offer to become head of Cornell’s Department of Plant Breeding in 1914. It was here over the next three decades that he achieved his world renowned reputation as a pioneer corn geneticist. He eventually built a corn breeding and genetics dynasty, mentoring dozens of graduate students, many that went on to become famous geneticists in their own rights, including another Nebraskan, George Wells Beadle. George Beadle, from Wahoo, was jointly awarded the Nobel Prize in 1958 for discovering the role of certain genes in producing enzymes that regulate biochemical pathways in cells.

Although Emerson concentrated on corn as a model crop while at Cornell, research in his later years additionally included more breeding studies with dry beans, which was an important crop in New York at that time. He was able to transfer resistance to the disease anthracnose into new dry bean cultivars and was thus credited with saving the dry bean industry in New York State from disaster and collapse.
Emerson’s Legacy in Nebraska

The name of Rollins Emerson remains alive today in Nebraska agricultural history, although his innovative investigations or even his existence during the early years of dry bean research in the U.S. are largely unknown. The bacterial wilt-resistant Great Northern dry bean cultivar, ‘Emerson,’ developed by UNL breeder Dermot Coyne in 1971, was named in honor of the eminent Nebraskan geneticist. Although many producers today are familiar with the cultivar (still being used in Nebraska 40+ years later), few know the identity of the honored individual or of his early contributions to the state of Nebraska and its agriculture.

Gregor Mendel and his peas – the origin of modern genetics

Bob Harveson – University of Nebraska – Lincoln Extension Plant Pathologist

This is part of a series celebrating the International Year of Pulses.

International Year of the Pulse

Peas have been cultivated for thousands of years and archeological evidence suggests they were a regular companion with wheat and barley. This crop’s origin is thought to be the same as that of the cereals, being native to the Fertile Crescent, an area of the Middle East stretching from the Persian Gulf, through modern-day southern Iraq, Syria, Lebanon, Jordan, Israel, and northern Egypt.

While the crop may be ancient, it has played a pivotal role in the creation and development of the modern science of genetics.

The Agricultural Monk

Gregor Johann Mendel was a person of German ancestry living as a monk in Brno, Moravia (present-day Czech Republic). He was educated at the University of Vienna in Austria and conducted experiments between 1856 and 1863 utilizing garden peas within a small five-acre plot on the monastery grounds of the Abbey of St. Thomas.

Mendel worked with seven distinct characteristics of pea plants: plant height, pod shape and color, seed shape and color, and flower position and color. He carefully sorted the progeny derived from the parent plants based on these characteristics and counted the number that inherited each character. As a result of these studies, he discovered that these heritable traits were passed on by the parents and were distributed among the resulting offspring in definitive mathematical ratios, which established specific laws of inheritance for the first time. For example, with seed color, he showed that when a yellow pea and a green pea were cross pollinated, the resulting offspring plant always produced yellow seeds. However, in the next generation of plants, the green peas reappeared at a ratio of 1:3 (green to yellow). These studies also recognized that some traits were dominant while others were recessive. This example shows that yellow was the dominant trait.

The Forgotten Birth of Modern Genetics

Although Mendel’s work was largely accurate, his ideas were never recognized by his peers during his lifetime (1822-1884). His findings were originally published in an obscure Austrian journal in 1866. He died in obscurity and his work went unnoticed until being rediscovered around 1900 by four scientists: the Dutch botanist Hugo de Vries, the German botanist and geneticist Carl Correns, the Austian agronomist Erich von Tschermak-Seysenegg (as a graduate student), and the American wheat breeder and agricultural economist William Jasper Spillman.

Farmers had known for centuries that crossbreeding animals or plants could favor certain desirable traits. As the 20th century dawned, these empirical observations could now be explained scientifically on the basis of the newly discovered ideas of Mendelian genetics. Mendel’s pea plant experiments established many of the rules of heredity, now referred to as the laws of Mendelian inheritance, which helped stimulate the rapid advances in genetics and plant breeding of the last century.

Avoiding damage to ornamentals and turf from herbicide applications

From IPM in the South by Rosemary Hallberg

By: Chris Marble, University of Florida

Proper use of herbicides is one of the cornerstones of a good weed control program – but bad things can happen when they are not used correctly. Compared to insecticides or fungicides, herbicides have a much greater potential to damage valuable ornamentals or turf, in some cases even when small mistakes are made. Luckily, if you follow a few key principles, damage can be avoided.

  • Applying the wrong amount of herbicide is the number 1 reason for causing damage to turf or ornamentals and the number 1 cause of weed control failures. Herbicides are designed to work within a narrow range – apply too much and damage can occur. Apply too little and weeds will not be controlled. The best way to prevent causing damage (also called phytotoxicity) is to properly calibrate equipment and use herbicides only in sites where they are labeled.
  • Identify the weed species. Properly identifying the pest you are trying to control is the first step in an Integrated Pest Management Program (IPM). Herbicide labels will contain tables showing the rates needed for a particular weed species or for a particular size of the weed. The lowest rate should be chosen for the weed species you are trying to control to improve the safety profile of that herbicide.
  • Know how far tree (and shrub) roots can extend. Many herbicides that are commonly used in turf areas contain warnings such as “Do not apply in areas that contain roots of desirable trees or ornamentals.” How far do tree roots extend? On average they extend close to three times the spread of the drip line (tree canopy) – which in some cases means well into turf areas. In these situations, choose herbicides that are not as prone to leaching or being absorbed by tree roots. Many turf herbicides are also prone to causing damage to nearby ornamentals through drift or volatility (i.e. 2,4-D and others) and should only be used in recommended areas.
  • Know how long it takes the herbicide to work. Damage can occur due to multiple applications being made in a short period of time. This is sometimes done because the herbicide seems to not be working, and the applicator thinks a repeated application is needed. For some herbicides, symptoms may not be noticeable for a week or longer depending upon environmental conditions. Know how long it will take the herbicide to work and then re-apply as needed. Note that some weed species will almost always required repeat applications for 100% control – each application should be made at the proper rate. Never apply higher than the labeled rate to try and achieve better or faster results. Following label recommended split applications (applying a lower rate at multiple timings) has also been shown to improve weed control and reduce phytotoxicity with many different herbicides.
  • Use adjuvants and surfactants carefully. Adjuvants and surfactants are often needed and/or recommended for use with certain herbicides but they may also increase the risk of temporary phytotoxicity to the turf. Only use the specific types of adjuvants or surfactants recommended on the product label and do not use more than the intended amount.
  • Use contact herbicides if spraying close to ornamentals. Glyphosate is a great product but if even a little gets on an ornamental it may never recover. Be careful using systemic herbicides around ornamentals (including thin barked trees and plants with green stems) or try to use contact action herbicides for small and annual weed species. Even if the ornamental is contacted by these herbicides, it will not move throughout the plant and is likely to recover.
  • Use good judgment. It seems obvious but it still happens – avoid herbicide applications in strong winds and use lower pressure to avoid potential herbicide drift damage. Always clean and flush hoses and tanks, especially when applying fungicides, insecticides, and herbicides from the same equipment. Only a small, residual amount of a herbicide such as atrazine left in the bottom of a spray tank can kill many different types of ornamentals. Also note label recommendations pertaining to weather and other environmental conditions. There are many herbicides that can cause unwanted damage to turf at high temperature (above around 90°F) but are safe during cooler times of the year.
  • Always read the label. We all know we are supposed to read and follow pesticide labels but the time invested reading herbicide labels is the most valuable time you can spend in developing and implementing your weed control program. Reading and following all parts of the label is the best way to ensure applicators are safe, the product performs as it was intended, and that we are protecting the environment

Distinguishing diseases from chemical injury in soybean

By Heather Marie Kelly, Extension Plant Pathologist, Institute of Agriculture, University of Tennessee

Soybean diseases and chemical injury can be difficult to correctly diagnose in the field.

Top side of leaves: frogeye leaf spot (FLS) on left and chemical burn on right
Picture 1 -Top side of leaves: frogeye leaf spot (FLS) on left and chemical burn on right
Bottom side of leaves: frogeye leaf spot (FLS) on left and chemical burn on right
Picture 2 – Bottom side of leaves: frogeye leaf spot (FLS) on left and chemical burn on right
Bottom side of leaves: frogeye leaf spot (FLS) on left and chemical burn on right
Picture 3 – Bottom side of leaves: frogeye leaf spot (FLS) on left and chemical burn on right

Some general information about diseases in soybean and common chemical injury follow to help distinguish between the two.

One of the first things to take notice of is if the newest growth on the plant has symptoms or not. Chemical injury will only occur on foliage that was out when the chemical was sprayed or from water splashing it up from the soil onto leaves, so new foliage will be green without symptoms. Symptoms of common foliar diseases in soybean, such as frogeye leaf spot (FLS), usually don’t develop until reproductive growth stages. Similar looking lesions can be common on earlier soybean caused by chemical burn and can be hard to distinguish, both can have a dark margin and lighter center (Picture 1). Although, chemical burn will usually be close to a perfect circle and FLS may be more angular in shape. The under sides of the leaves are the best area to distinguish the two (Picture 2 and 3). Chemical burn will have a bleached out center (lesions on the right) whereas FLS will have a tan to grayish center and if the lesion is sporulating, in the very center of the lesion there will be a dark black area (lesions on the left).

Pre-emergence herbicides, especially PPO inhibitors and photosynthetic inhibitors (metribuzin), can injure seedlings, particularly when cool temperatures coincide with rain soon after emergence. Spotty necrosis can occur when rain splashes droplets of residual herbicide from the soil onto emerged seedlings or lower leaves. Common symptoms of seedling diseases that are not usually associated with chemical injury include rotten, mushy seedlings with poorly developed roots, water-soaked lesions on the hypocotyl, cotyledons, or stem, and stunted or wilted seedlings.

If unsure if you have a disease or chemical injury contact your local county agent or send samples to your state diagnostic lab.
