广泛应用数量遗传学方法对作物农艺性状的遗传力进行估算,以确定选择的直接指标;估算杂种后代的遗传进度以决定育种的规模,可提高育种效果。国内外育种工作者在大豆方面也进行了研究,为新品种选育提供了依据。在本文内,拟就通过大豆杂交后代群体主要农艺性状遗传力和遗传进度的估测,确定我们育种的直接选择指标及育种规模。
Quantitative genetic methods are widely used to estimate the heritability of agronomic traits in crops to determine the direct index of selection. Estimating the genetic progress of hybrid offspring to determine the scale of breeding can improve the breeding effect. Domestic and foreign breeders also conducted research on soybean, which provided the basis for breeding new varieties. In this paper, we plan to determine the direct selection index and breeding scale of our breeding through estimating the heritability and genetic progress of the main agronomic traits in the offspring of soybean cross.
