Complementary approaches towards the discovery of genes controlling yield in pea

International audience; Pea is one of the most important grain legumes in the world. Improving pea yield is a critical breedingtarget in the current context of consumers’ increasing demand for plant proteins for food and feed. Becauseof its polygenic nature and the impact of the environment, breeding for higher yield is challenging. Weinvestigated the genetic determinism of yield (SW), seed number (SN) and thousand seed weight (TSW) usingboth linkage and linkage-disequilibrium approaches.Nine interconnected mapping populations, representing a total of 1,213 recombinant inbred lineswere phenotyped for SW, SN and TSW in six different field environments. These lines were genotyped usingthe Gen…
