Research Project: Dry Pea (PISUM SATIVUM, L.) Breeding

Location: Grain Legume Genetics Physiology Research

2013 Annual Report

1a. Objectives (from AD-416):
The objectives of this proposal are to develop improved varieties of green, yellow and marrowfat spring peas and green winter-hardy peas.

1b. Approach (from AD-416):
Screen breeding lines for resistance to soilborne pathogens, viral pathogens and foliar fungal pathogens. Develop SCAR markers from previously identified PCR markers associated with tolerance to Aphanomyces root rot. Establish observation nurseries, preliminary yield trials and advanced yield trials in WA and ID. Evaluate breeding lines for cooking quality and nutritional quality. Documents Trust with USA Dry Pea and Lentil Council. Log 41108.

3. Progress Report:
This research relates to objective 1 of the 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 Washington and Idaho. 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.
