Research Project: Developing Early Maturing Chickpea Varieties with Ascochyta Blight Resistance

Location: Grain Legume Genetics Physiology Research

Project Number: 2090-21000-029-12
Project Type: Trust

Start Date: Jul 01, 2010
End Date: Dec 31, 2014

Objective:
The primary objective of this proposal is to develop improved chickpea varieties. Sub-objectives include making crosses between elite chickpea breeding lines and screening breeding materials for disease resistance, seed protein content and seed mineral concentration.

Approach:
Cross will be made in the greenhouse and the field between elite chickpea lines and varieties. Parental lines will be selected based on performance in preliminary and advanced yield trials for a range of agronomic traits including seed size and color, yield, and early maturity. Hybrids are increased in the greenhouse and subjected to multiple cycles of self pollination to produce segregating bulk populations. Segregating bulk populations (F3-F6) will be grown in the field and selected for seed type (size, shape and color), height and lodging tolerance, and early maturity. Preliminary selections will be evaluated in the field at a single location. Advanced selections will be evaluated in yield trials conducted at multiple locations. Breeder seed will be produced from two elite breeding lines for subsequent varietal releases. Single plant selections, preliminary breeding lines and advanced breeding lines will be screened for resistance to Ascochyta blight. Preliminary and advanced breeding lines will be screened for seed protein content and seed mineral concentration.
