Breeding effects on the genotype × environment interaction f

发布时间：2023-04-03 18:58

　　This study evaluates the changes caused by breeding in the genotype by environment(G × E) interaction of the durum wheat varieties most widely cultivated in Spain after the Green Revolution. A set of 12 cultivars was tested in 27 environments, which are understood as the combination of different sites, years, and treatments(water regime and planting dates), representative of the durum wheat growing conditions in Spain with average grain yields(GY) ranging between 2.8 and 9.1 Mg ha^-1. ...
