Understanding Soybean Maturity Groups in Brazil: Environment, Cultivar Classification, and Stability

Abstract: U nderstanding and quantifying photoperiod × temperature interactions often directly aff ects soybean [Glycine max (L.) Merr.] breeders and producers when selecting varieties, determining dates of planting, predicting dates of fl owering and maturity, and predicting fi nal yields (Zhang et al., 2001). Eff ect of the photoperiod response on area of adaptation is more pronounced in the soybean than in any other major crop. As soybean is classifi ed as a short-day plant, sensitivity to photoperiod is a hindering … Show more

“…This range of variation had also been verified by Alliprandini et al [2], making it possible to classify genotypes into distinct RMG, ranging from 5 to 9. The effects of the genotype-location interaction were also significant for all three traits evaluated, but with lower variability compared to the main effects.…”

“…Using the fitting equation, RMG of the remaining genotypes were established according to the method of Alliprandini et al [2]. Subsequently, the relative maturity of each genotype was compared with that reported previously [19].…”

“…According to Peluzio et al 26 and Santos et al 27 , in evaluations of soybean genotypes in southern Tocantins state, the cultivars M9144 RR and M9056 RR are classified as late maturation cycle, while the cultivars P99R01 and JULIANA RR present average maturation cycle. Thus, excludes itself the tendency of only late cycle genotype be superior in unfavorable environmental conditions, by its ability to develop, throughout the vegetative stage, mechanisms of tolerance to stress 28 .…”
