Research Project: Montana Western Regional Cool Season Food Legume Evaluation Trials
2013 Annual Report


1a.Objectives (from AD-416):
Evaluate elite pea, lentil and chickpea breeding lines developed by the USDA Agricultural Research Service (ARS) and NDSU cool season food legume breeding programs, along with check varieties, in yield trials conducted in several diverse pulse production regions in Montana and North Dakota.


1b.Approach (from AD-416):
Field trials will be conducted in Richland, MT, Moccasin, MT and another location to be determined in Montana, along with Hettinger, ND, Williston, ND, and another location in ND to be determined. Turkish Red lentil trials will include the check varieties CDC-Redberry and CDC-Red Rider, and two advanced selections each from the USDA-ARS and NDSU breeding programs. Eston trials will include the check varieties Eston and Essex and one or two advanced lines from both breeding programs. Spanish Brown trials will include the check varieties Pardina and Morena along with two advanced ARS breeding lines. Medium-large yellow lentil trials will include the check varieties CDC Grandora, CDC Greenland, Riveland, Richlea, and one line each from both breeding programs. Yellow pea trials will include the check varieties Carousel and Universal, along with three advanced lines from each breeding program. Green pea trials will include the check varieties Aragorn and Banner along with three advanced lines from each breeding program. Chickpea trials will include the check varieties CDC-Frontier, Sawyer, and Sierra and five advanced ARS breeding lines Prior to planting all seeds will be coated with a treatment consisting of several fungicides, an insecticide (Cruiser) and molybdenum to promote nodule formation on roots. Three replicated plots (1.5 m x 6.1 m) will be planted at a density of 44 seeds/m2 for each entry at each location. A post plant/pre-emergence application of herbicide will be applied to control weeds. A schedule of different fungicides will be applied on chickpea plots during the growing season to manage ascochyta blight. Approximately 14 d before harvest a single application of gramoxone will be applied to chickpea plots to promote dessication. Plots will be evaluated during the growing season for plant height and days to flower. Average seed weight (g/100 seeds) will be determined after seed is harvest and cleaned. ANOVA will be performed on yield data to detect significant genotype, environment, and genotype x environment interaction effects on yield.


3.Progress Report:

This research relates to objective 1 of the associated inhouse project “Develop and release new varieties and germplasm of peas, lentils, and chickpea that have higher seed mineral concentrations; improved host-plant resistance to Aphanomyces root rot, Sclerotinia wilt and Ascochyta blight; and higher yields than existing commercial varieties”.

In 2013, advanced yield trials for peas, lentils, and chickpeas were planted at several locations in Montana. Breeding lines, commercial varieties, and populations are being evaluated in field nurseries for reaction to several diseases including Ascochyta blight, Fusarium wilt, and Aphanomyces root rot. Chickpea populations are being examined with DNA markers in the laboratory and evaluated in the field for important traits including disease resistance, maturity, yield, and seed size.
