在云南省元谋县进行了胡麻杂交组合1S×873、1S×95005制种的播期试验，结果表明，胡麻杂交制种组合在元谋县的最佳播期为9月下旬，其中9月22日播种的1S×873组合产量最高，折合产量为751.75 kg/hm2；9月30日播种的1S×95005组合产量最高，折合产量为618.25 kg/hm2。组合1S×873、1S×95005 9月30日播种的制种质量最好，可育株率均为0。

The seeding experiment on sowing date of 1S×873、1S×95005 of two flax hybrid seed production combination was conducted in Yuanmou county of Yunnan. The results showed that the optimum sowing date of flax hybrid seed production combination in Yuanmou county in late September， which 1S × 873 combinations at sowing of 22 September was the highest yield， equivalent yield was 751.75 kg/hm2； 1S × 95005 combination at sowing of 30 September was the highest yield， equivalent yield was 618.25 kg/hm2. The rates of fertile plants of 1S × 873， 1S × 95005 combinations at sowing of 30 September was zero.
