Objective

To introduce new diversity into pea breeding material to improve the crop in key traits, and to combine these traits into individual varieties.

Outcome

Three diverse varieties identified as donors of heat stress resistance, high seed protein content, and improved Aphanomyces root rot resistance were introgressed as short chromosomal segments into a common genetic background. This diversity was introgressed into CDC Amarillo which is a high yielding pea cultivar. Three recombinant inbred line (RIL) populations and three chromosome segment substitution line (CSSL) libraries were generated using a combination of traditional crossing and marker-assisted selection. The RILs and CSSLs are being tested in repeated field trials for key traits related to pea performance in western Canada over the coming years. The genetic resources created in this project will be useful for functional genomics studies and pyramiding of genes associated with heat stress resistance, high seed protein content, and Aphanomyces root rot resistance in pea.
