作者研究了秈粳杂种的生育特性及结实性等经济性状的遗传变异,认为以出穗期为主要指标进行选择,结合其他性状的变异动态,逐步确立优良系统,有助于提高选择的效率,和建立较为合理的杂交育种程序与方法。
The authors studied the genetic variation of fertility traits and seed set traits in indica-japonica hybrids. It was suggested that choosing the heading date as the main index and combining with the variation dynamics of other traits would establish an excellent system step by step and help to improve the efficiency of selection. And to establish a more reasonable hybrid breeding program and method.
