Schedule
9:00 - Registration. Coffee and donuts will be served.
9:30 - Tour starts. It will last for 2 to 2-1/2 hours when we will return to Panhandle Station in Scottsbluff for lunch and there will be time for questions and discussion with our speakers.
Speakers and Topics
Jim Steadman - "Screening for Resistance to Rust and White Mold in Different Bean Classes."
Pathogen variation influences the search for disease resistance, but we are characterizing both pathogens and using relevant races to find resistant bean lines.
Bob Wilson - "Influence of Different Levels of Corn Residue on Pre-emergence and Post-emergance Herbicde Performance in Dry Beans."
The project demonstrates the influence of corn residue on dry bean emergence, early season vigor, weed emergence, and herbicide performance.
Carlos Urrea - "Bean Coordinate Agricultureal Project Experiments."
About 453 beans from different market classes are being grown in replicated trials at ND, MI, CO, and NE. We are correlating agronomical data with nutritional traits for the beans grown under several growing conditions. We are also testing 100 lines under drought conditions (ND, MI, CO, NE, and WA) to estimate how drought affects the nutritional value in dry beans.
Carlos Urrea - "Drought Experiments in Beans".
Experiments on drought to locate the genes responsible for drought tolerance are being conducted in two mapping populations. A shuttle breeding between Puerto Rico and Nebraska initiated in 2006 is in place. Several lines within different market classes are being identified with drought and heat toleance plus disease resistance.
Carlos Urrea - "Breeding Several Market Classes for Western Nebraska".
Thirteene elite great northern and pinto lines are being evaluated in several locations in the Panhnadle (Hemingford, Gering Valley, Bayard, Scottsbluff, Mitchell, and Morrill). Small red, black, light red kidney, and cranberry beans are showing promising performance.
Jeff Bradshaw - "Unique Stategies for Pursuing Insect Resistance in Dry Beans".
Two insects primarily impact dry beans in western Nebraska; western bean cutworms and Mexican bean beetles. Both of these insects cause damage mostly by chewing on plant foliage and pods. Last year we began to develp a leaf assay to screen for varietal resistance to these insects. We continue this work; however, we are also beginning to integrate parasitoid activity with varietal resistance. Additionally, we have also successfully integrated a modern gene expression/gene silencing tool for use in some dry bean varieties that may also be useful to our understanding of insect pest control in dry beans. Both the use of parasitoids and genetic tools for insect pest control in dry beans will be discussed.
Gary Hergert - "Fertilizer Management for No-till Dry Bean Producation with Limited Irrigation".
The objective is to determine the yield of 2 pinto and 2 great northern dry bean varieties planted no-till into corn residue as part of a 4-crop roation that receives water allocations of 4, 8, or 12 inches of irrigation with zero and 60# N/acre.
Jim Schild - "Planting Dates, Planting Populations, and Effects of Defoliation on Dry Beans".
All these factors can influence plant performance and yield throughout the season, so these aspects are being explored to determine extent of losses to dry beans.
Bob Harveson - "Are Copper Applications Capable of Effectively Managing Bacterial Wilt Infections in Dry Beans?"
Copper products have been demonstrated to manage bacterial diseases such as halo blight and brown spot, but not as consistently with common blight. We do not know whether these products will help reduce problems due to bacterial wilt, thus we are testing this concept in 2011.
