【摘要】 考虑育种目标的要求,对多个独立的主成分性状进行综合优化,建立了综合主成分性状的数学模型.综合主成分性状是s个表型方差(遗传方差)最大的主成分性状在育种目标约束下表型方差(或遗传方差)极大化下的线性组合,作为育种指标,选择效果好,预见性强.更多还原

【Abstract】 Comprehensive principal component trait is set up by restriction of breeding objective using integration and optimization methods.It is a linear combination of straits with principal component which have larger phenotype or genotype variance.As selection index,ti is unique,predictable and can result in good selection effect.更多还原
