中国高粱胞质雄性不育系吉农105的研究 Ⅱ.主要农艺性状的配合力分析

Study on the Cytoplasmic Male Sterile Line of Chinese Sorghum Jinong 105 The Combing Ability Analysis of Main Characters

按不完全双列杂交法对中国高粱细胞质和Ａ１型细胞质进行了生育期等７个主要农艺性状的配合力分析。结果表明：一般配合力主要受核基因控制，但胞质基因对核基因的表达也有一定的影响。中国高粱细胞质虽未造成大多数被研究性状配合力的显著差异，但它在生产上利用，对增加胞质多样化、降低遗传脆弱性具有重要意义。

The combing ability of 7 main agronomic characters was analyzed in this paper with NC II device in the Cytoplasmic of Chinese sorghum and Al Cytoplasmic The results indicated as follow:The general combing ability was controlled by nucleus gene,but Cytoplasmic gene affected the expression of nucleus genes.The combing ability of most characters were not affected significantly by the Cytoplasmic of Chinese sorghum,but if could increase the diversity of Cytoplasmic,and detract the genetic weak.
