Haplotype distribution and frequency change of TaARF4-B. (A) Distribution of two TaARF4-B haplotypes in 157 landraces of ten Chinese major wheat zones. (B) Distribution of two TaARF4-B haplotypes in 348 modern cultivars of ten Chinese major wheat zones. 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, South-western Winter Wheat Region; V, Southern Winter Wheat Region; VI, North-eastern Spring Wheat Region; VII, Northern Spring Wheat Region; VIII, North-western Spring Wheat Region; IX, Qinghai–Tibet Spring–Winter Wheat Region; X, Xinjiang Winter–Spring Wheat Region. (C) Haplotype frequency change of TaARF4-B in Chinese wheat breeding programmes. The left y-axis shows frequencies of TaARF4-B in Population 5 over decades. The right y-axis shows PH in Population 5 over decades. Accessions released in the pre-1960s, 1960s, 1970s, 1980s and post-1990s are numbered 37, 55, 102, 106 and 34, respectively. Thirteen accessions with unknown release dates were excluded. Error bars are 2 × s.e.
