Yield potential and selection of off-season maize for silage and grain using GT Biplot under limited water and frost

Maize silage has been used as a forage reserve strategy for critical periods or continuous use in animal feed. However, new genotypes and their potential must be identified. Thus, this study aimed to evaluate the of maize grain one off-season midwest region Brazil, under limited water frost, select them dual purpose (silage grain) using GT Biplot tool. The experiment was performed at Embrapa Western Agriculture autumn-winter season 2021 Dourados, Mato Grosso do Sul, Brazil. experimental design consisted randomized blocks six (BRS1010, KWS9606, 1P2224, 1Q2383, BRS3046, CAPO) with five replications no-tillage. Silage points were evaluated harvest when milk line ¾ grains maturation stage (dry plant). 1P2224 1Q2383 present (high green dry biomass) yield potential. tool identified genotype superior suitable cultivation parent breeding program Brazil evaluations frost.
