A quantitative genetic framework highlights the role of epistatic effects for grain-yield heterosis in bread wheat.

Nature genetics - 1 Dec 2017

Jiang Yong, Schmidt Renate H, Zhao Yusheng, Reif Jochen C

Abstract excerpt

Increasing wheat yield is a key global challenge to producing sufficient food for a growing human population. Wheat grain yield can be boosted by exploiting heterosis, the superior performance of hybrids compared with midparents. Here we present a tailored quantitative genetic framework to study the genetic basis of midparent heterosis in hybrid populations derived from crosses among diverse parents. We applied...
