“…In China, genetic progress in wheat yield potential has also been studied in different regions (Tian, Jing, Dai, Jiang, & Cao, 2011; Wu et al., 2014; Zhou, He, et al., 2007; Zhou, Zhu, et al., 2007; Zhou et al., 2014). The annual GY genetic gains were 51.30 kg ha −1 yr −1 , or 0.60%, in 18 leading cultivars released between 1981 and 2008 in Henan Province, eastern‐central China (Zheng et al., 2011), 62 kg ha −1 yr −1 , or 0.85%, in 15 cultivars released from 1969 to 2006 in Shandong Province on the eastern seaboard of central China (Xiao et al., 2012), 57.5 kg ha −1 yr −1 , or 0.70%, in 26 leading wheat cultivars released from 1950 to the present time in the southern Yellow and Huai Valleys Winter Wheat Zone (Gao et al., 2017), and 47.4 kg ha −1 yr −1 , or 0.717%, in nine milestone cultivars released between 1964 and 2007 in Hebei Province, North China Plain (Yao et al., 2019). These results indicate that significant genetic gains have been achieved in GY of Chinese wheat cultivars.…”
