“…This is higher than the findings for spring bread wheat (43.5 kg ha −1 per year or 0.51% per year) for a similar period and in the same Mediterranean environment [8]. It is also clearly higher than the increase reported for durum wheat in Spain (24 kg ha −1 y −1 ; 0.44% y −1 ) from 1980 to 2003, with no clear additional improvements occurring thereafter [26]. In northwest Mexico, under fully irrigated conditions, the genetic progress of spring durum and bread wheat varieties developed by CIMMYT was 0.49% and 0.41% per year, respectively, between 1966 and 2003 [27], and 0.88% per year when comparing eight bread wheat cultivars released between 1962 and 1988 [28].…”

“…The yield potential achieved in Chile is clearly higher than values recorded in the Mediterranean basin. For example, high-yielding conditions in Spain usually do not surpass 8 Mg ha −1 [25,26], which is clearly lower than those achieved in the Mediterranean conditions of Chile. The high-yielding conditions in Spain usually imply several irrigations per season, particularly during the critical period from stem elongation to the middle grain filling, which alongside natural rainfall aims to balance the water lost due to accumulated evapotranspiration.…”

“…Although far less common, analyses of short-term breeding effects (Chairi et al, 2018) are also done for this reason. Cultivars of the current study were released in the US southern Great Plains from 2007 to 2016.…”

“…Conclusions derived from some studies considering in particular the most recent yield gains from long-term breeding gains (e.g., Acreche et al, 2008;Flohr et al, 2018;Lo Valvo et al, 2018;M. Sanchez-Garcia et al, 2012) or from studies exclusively focused in the recent past (e.g., Chairi et al, 2018) indicate that recent gains in yield have been much lower than in previous decades and in some cases rather marginal or inexistent.…”

“…Since the Green Revolution, the introduction of dwarfing genes has reduced plant heights and increased lodging resistance, both of which have played a significant role in increasing wheat yields [22,28,32,40,41]. Our results showed that plant height decreased with year of release; indeed, the length of five internodes decreased significantly with year of release, which contributed to the decline in plant height.…”
