“…However, all cultivars used in the experiment were or are most widely grown in this region, which could also represent the real progress in wheat production. The present study showed that the genetic gains in wheat GY in southwestern China from 1969 to 2012 were 0.69%, or 52.52 kg ha −1 yr −1 , which is similar to the results seen in Henan Province between 1981 and 2008 (Zheng et al, 2011) and in Hebei Province between 1964(Yao et al, 2019 but is lower than the rate of gain observed in…”

“…Some studies showed little genetic change in DM accumulation with years of release (Lo Valvo, Miralles, & Serrago, 2018;Zheng et al, 2011), whereas other studies reported genetic progress (Aisawi et al, 2015;Shearman, Sylvester-Bradley, Scott, & Foulkes, 2005;Wu et al, 2014;Xiao et al, 2012). In yield components, Beche et al (2014) confirmed that genetic progress in GY was related to the increase in grain number (GN) per square meter, whereas the findings in Gao et al (2017) and Yao et al (2019) demonstrated that the genetic gains in GY was associated with the increase in both GN per square meter and grain weight. Photosynthesis of crops plays a crucial role in GY, and ∼90% of DM accumulation is derived from photosynthetic products (Makino, 2011).…”

“…It is important to note that many studies have reported that plant height was reduced when comparing modern genotypes with old ones [15,16,[41][42][43][44]. However, the varieties employed in our study were all semidwarf; therefore, plant height did not change significantly across year of release.…”
