摘　　要：为制定黔油 12号大面积制种技术方案 ,明确该品种父母本的最佳播差期和最佳播期 ,提高异交结实率和制种产量 ,1999年 9月 18日至 11月 6日共进行了 9期相隔 6 d的父母本播期试验。结果表明 :父母本最佳播差期为 6 d;最佳播期在 9月中旬至 10月中上旬 (父本最迟播期为 10月 12日 ) ;在最佳播期内 ,父本比母本提前 6 d播种的花期相遇较好 ,异交结实率高 。To formulate large scale seed production techniques of Qianyou 12, and to identify the best sowing time and the separate sowing time for male and female parents for increasing fecundity and yield, 9 sowing date experiments with 6 days apart for male and female parents were conducted from September 18 to November 6. The results are: 1. the best separate days of male and female parents sowing are 6 days apart . 2. the best sowing days are between mid September and early October (the latest sowing time is October 12). 3. it can bring high fecundity and yield when the sowing date of male parent is 6 days earlier than that of female parent.
