中国大豆种子蛋白中SBTI等位基因频率及分布

APPLICATION OF THE PRINCIPAL COMPONENT ANALYSIS IN MILLET BREEDING

摘要:

本文对我国大豆种质资源1.9万份进行了SBTI等位基因电泳分析,找出Ti^a、Ti^b、Ti^c三种基因型的频率及分布规律,结果全部具有Ti^a型,北方省品种中较多出现Ti^b,南方品种中发现Ti^c型。Ti^a·Ti^b·Ti^c三者频率比例为100∶1.3∶0.2,未发现不含胰蛋白酶抑制剂的ti型材料,栽培豆Ti类型单一,野生豆Ti类型变异较大。

Abstract:

This paper explored the application of principal component analysis to millet breeding program. It was shown that the results from evaluation of crosses and parents by the analysis mothed were consistent with those from practical breeding, indicating the possibility of application of principal compoent analysis. It is also helpful to use this mothed in the selection scheme of millet crosses, with computerizing data.
