Heterosis and Combining Ability Studies for Quality Traits in Soybean [Glycine max (L.) Merrill]

Genetic and phenotypic parameters associated with soybean progenies in a recurrent selection program

“…It is a tool initially developed for allogamous crops; however, application in autogamous plants, such as wheat, oats, rice, and common bean have increased in recent years. In the case of soybean, there are reports of the use of recurrent selection outside of Brazil for grain protein content (Patil et al 2017, Rialch andSharma 2019) and grain yield (Sumarno and Fehr 1982, Posadas et al 2014, Vello and Nazato 2017, Nie et al 2019, Hegstad et al 2019. However, it should be highlighted that for the purpose of expanding the genetic variability of the base population of the recurrent selection program, the authors used exotic germplasm, i.e., germplasm with low adaptability and, likewise, lower frequency of favorable alleles.…”
