摘要
在对水稻籼粳交F1、F2 代及籼粳杂交育成品种进行分类的基础之上 ,分析籼粳交F1、F2 代及籼粳杂交育成品种亚种分类性状与经济性状的相关关系。研究结果表明 :籼粳交F1、F2 代及籼粳杂交育成品种亚种分类性状与主要经济性状存在密切的相关关系 。
In this study,the correlations between classifiable characters and economic characters of hybrid breed between indica and japonice rice was studied after studying classification of F 1?F 2 and varieties bred through hybridization between indica and japonica rice,the results showed:there have close correlations between classifiable characters and economic characters of hybrid bred between indica and japonica rice.The parents and hybrid bred were reasonably selected using Cheng's morphology index according to the correlations between classifiable characters and economic characters of hybrid bred between indica and japonica rice.
