摘  要:
对杂交水稻新组合的区试资料进行了初步分析,认为1、D优10号丰产性好、适应性强;2.杂交水稻产量与其稳定性参数bi间相关性不显著(V·bi=0.293);3.杂交水稻产量的稳定性似与其有效穗数相关联,且可能与其主要农艺性状在不同环境条件下变化的协调性有关。

摘  要:
This study analysed the yield stability of new hybrids of rice throgh the data from cultivar regional tests in 1987. The results showed as follows: 1. The yield and yield stabity of Dyou 10 are the best in the regional tests. 2. The correlation coefficent between mean yield and regression coefficient bi were nonsignificant) r_x. bi=0.293). 3. The hybrid yield stability was associated with the harmony of main characters changes to a series of enviroments.
