Abstract

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

限水限霜条件下GT Biplot对淡季青贮玉米和籽粒玉米的产量潜力和选择

玉米青贮已被用作关键时期或连续使用的饲料储备策略。然而，必须确定新的基因型及其潜力。因此，本研究旨在评估巴西中西部地区一个淡季在有限水和霜冻条件下青贮和谷物玉米基因型的潜力，并使用GT Biplot工具选择用于这种双重用途(青贮和谷物)的玉米。该实验于2021年秋冬季节在巴西南马托格罗索州杜拉多斯的Embrapa Western Agriculture进行。试验设计采用6个玉米基因型(BRS1010、KWS9606、1P2224、1Q2383、BRS3046和CAPO)随机区，5个重复，免耕。青贮点是在收获时谷物乳线为3 / 4时和玉米籽粒成熟期(干株)时进行评价的。1P2224和1Q2383玉米基因型具有青贮(高绿生物量和高干生物量)和籽粒产量潜力。GT Biplot工具鉴定出1P2224基因型优越，适合栽培或作为亲本在巴西中西部地区的育种计划中进行青贮和一个淡季在限水限霜条件下的粮食产量评估。
