作物产量等性状大多为数量性状,其遗传受多基因控制,且易受环境条件的影响而产生不能遗传的变异.本文运用数量遗传的原理和方法,估算了春小麦几个主要数量性状的广义遗传力、相关系数、遗传进度及选择指数等遗传参数,以供提高育种效率参考. Most of the crop yield and other traits are quantitative traits, and their inheritance is controlled by polygenes, which are easily affected by environmental conditions and can not produce genetic variation.In this paper, using the principles and methods of quantitative inheritance, the generalized inheritance of several major quantitative traits in spring wheat Force, correlation coefficient, genetic progress and selection index and other genetic parameters for improving breeding efficiency reference.
