Selection strategies in agronomic characters in progenies F3:4 of transgenic soy RR

ABSTRACT The selection indexes aggregate information to multiple characters and, with this, they are able carry out the of a set variables simultaneously. objective was verify genetic potential agronomic traits and select soybean F3:4 progenies based on different strategies. 123 parents were sown in randomized blocks two replications. gains direct by indexes, sum “ranks” genotype-ideotype lower for all when compared indirect selection. rank index stood achieving highest total gain 37.11%. obtained (-0.48%) character number days flowering (-0.54%) reached negative attribute insertion height first pod -1.82%. population is high allows strategies be applied reach superior genotypes. UFU 72, 116, 86, 45, 117, 56, 5, 106, 6, 4, 73, 101, 96, 90, 123, 88, 65, 70, 3, 69 37 selected both indexes. 88 agronomically selection, as Mulamba Mock (1978) selections genotype-ideotype.
