Figure 4From: Homologous haplotypes, expression, genetic effects and geographic distribution of the wheat yield gene TaGW2TaGW2-6B haplotype distribution in ten Chinese wheat ecological regions. A, TaGW2-6B haplotype distribution in 151 Chinese landraces; B, TaGW2-6B haplotype distribution in 320 modern cultivars. I, Northern winter wheat region; II, Yellow and Huai River valley winter wheat region; III, Low and middle Yangtze River valley winter wheat region; IV, Southwestern winter wheat region; V, Southern winter wheat region; VI, Northeastern spring wheat region; VII, Northern spring wheat region; VIII, Northwestern spring wheat region; IX, Qinghai-Tibet spring-winter wheat region; X, Xinjiang winter-spring wheat region.Back to article page
