春小麦主要营养品质性状的配合力分析

Analysis on the Combining Ability of Quality Characteristics for Main Nutrition of Spring Wheat

本文对５个春小麦品种的蛋白质含量、赖氨酸、色氮酸、蛋氨酸含量进行了完全双列杂交的配合力分析。方差分析表明，除蛋氨酸（克／１００克蛋白质）的一般配合力外，其它品质性状的一般配合力和特殊配合力方差均达到了显著或极显著水平、依据一般配合力效应，特殊配合力效应及特殊配合力方差，讨论了亲本品种有关性状的遗传特．点及其在育种中的应用。

Combining ability of seven characteristics of content of protein,lysine tryptophan and methionine etc of five spring wheat varieties were estimated in matins pattern of diallel system (inctuding reciprocal crosses),The result showed that general and specific combining abitity of others quality characteristics were statisticatly significant at levels of 0'.05 and 0.01,respectively.As shown by variance analysis except general Combining ability of methionine (g/100g protein ).the heredity for the characteristics in question of the parents were studied,and the use value of the parents in cross breeding was also evaluated.
