| 摘 要： | 为给贵州省杂交水稻新组合的高产制种提供理论参考,对杂交水稻新组合奇优894父母本的不同栽插模式父母本的分蘖动态、开花时间、母本结实率、制种产量进行比较分析,结果显示:以杂交水稻组合奇优894的父母本都采用三角形栽插,父母本行比为2∶16的制种效果最好,利用这种栽培模式父母本有效分蘖数多、开花时间长、母本的结实率高,杂交种子产量高达301.2 kg/667m~2.为杂交水稻新组合的高产制种,提供了一套全新的栽培模式.

| Abstract: | The tillering trend and flower time of male and female parents, setting rate of female parent and seed yield of Qiyou 894 (a new hybrid rice combination) under different planting patterns were analyzed to provide a theoretical reference for its high seed yield. The results showed that the ratio was of the highest seed yield. More effective tillers, longer flowering period, higher setting rate of female parent and 301.2 kg/667m~2 of seed yield can be obtained by using the new planting pattern in Qiyou 894. |
