| Abstract: | The cultural experiment for two-line indica hybrid rice-2301S/H7058 was carried out in Hefei, Anhui province. Some results were obtained by using correlation and path analysis: Functional seedlings and high amount of tillers had significant effect on productive panicles, and tillering characters was affected by seedling age and sheer amount of nitrogenous fertilizer slightly; filled grains per panicle and productive panicles had significant effect on yield, and transplanting density was the important restrictive role. And then, auxiliary experiment indicated the optional seedling period was from the end of April to early of May. |
