Abstract: The aim of this study was to estimate genetic and phenotypic parameters
associated with progenies from the recurrent selection program for
grain yield in soybean. The evaluation of S0:1 progenies was in Lavras in the
2015/2016 crop year. The S0:2 progenies were evaluated in Lavras, Nazareno,
and Itutinga. The S0:3 progenies were evaluated in Lavras, Ijaci, and Itutinga in
the following crop years. The following traits were evaluated: days to flowering,
days to full maturity, bottom pod height, plant height, lodging, and grain yield.
The expected gain and gain achieved from selection, genetic correlation, and
correlated response were estimated. The variance components show variability
among the progenies. It was possible to obtain gains from selection for grain
yield for all selection intensities (1, 5, 10, 15, 20, 25, and 30%). The variability
and the high performance of the progenies indicate that implementation of the
recurrent selection program can be successful.
