| 摘 要： | 对杂交粳稻组合3优18在不同父母本行比、母本栽插密度等处理下的异交结实率与制种产量进行分析,结果表明:1:6的父母本行比是最佳行比配置,母本密度株行距18cm×22cm为获得高产的最优配置;父母本花时不遇、柱头外露低等种性是制约制种产量进一步提高的主要限制因子。

| Abstract: | The kernel set and seed production of 3 You 18,a hybrid japonica rice combination,were analyzed under different ratios of spaces between rows of parents and transplanting densities of female parent.The results showed that the ratio of one row male parent to six row female parent was the optimal collocation and 18 cm × 22 cm,the space in the row by space between the rows,obtained the highest yield;asynchronous flowering time and low percentage of exerted stigma were the main factors inhibiting seed yield increasing. |
