Association of SNP markers with pea grain protein and grain yield traits in Italy : preliminary results

Grain yield and quality are the main economically important traits in breeding of field pea (Pisum sativum L.). The objective of our work was investigating trait-marker associations in elite pea germplasm, with the final aim to develop marker-assisted selection procedures for these traits. The genetic base for this study was represented by three connected recombinant inbred line (RIL) populations obtained from paired crosses between three genotypes (the varieties Attika, Isard and Kaspa) which featured different geographical origin and outstanding adaptation to Italian cropping environments. At least 86 F7 lines per RIL generated by single-seed descent were evaluated for grain yield, plant …
