Example Embodiment
[0040] Example 1
[0041] In 2004, this method was applied to Liaoyou 1052 in Liaoyang, with an area of 400 mu, and the final average seed production reached 265 kg / mu.
[0042] 1. Variety selection
[0043] For seed production, the variety was Liaoyou 1052, the male parent C52 had a sowing period of 110 days, and the female parent 105A had a sowing period of 105 days. The male parent has a long sowing period. Combined with the local climate conditions in Liaoyang, the rainy season is in late July. It can be determined that the male parent can avoid the rainy season by sowing after April 20. According to the sowing date of the parental parent, combined with the sowing test in stages over the years, it can be determined that the sowing date of the female parent is 10 days later than that of the male parent, and the sowing date will be on April 30. Mark the leaf age before transplanting. When transplanting, the leaf age of the male parent is about one leaf larger than that o...
Example Embodiment
[0054] Embodiment 2
[0055] In 2004, this method was used to produce seeds Liaoyou 9952 in Liaoyang, with an area of 200 mu, and the final average seed production reached 245 kg / mu.
[0056] 1. Variety selection
[0057] The variety is Liaoyou 9952, the male parent C52 has a sowing period of 110 days, and the female parent 99A has a sowing period of 110 days. The male parent's sowing period is the same. Combined with the local climate conditions in Liaoyang, the rainy season is in late July. It can be determined that the parent parent can be planted after April 20 to avoid the rainy season. According to the sowing date of the parental parent, combined with the sowing test in stages over the years, it can be determined that the parental parental sowing date is the same. The leaf age is marked before transplanting, and the leaf age of the parents is basically the same when transplanting.
[0058] 2. When sowing, it should be sown thinly, and the amount of seeds per square ...

[0067] Example three
[0068] In 2005, this method was applied to Liaoyou 1052 in Liaoyang, with an area of 400 mu, and the final average seed production reached 270 kg / mu.
[0069] 1. Variety selection
[0070] The variety is Liaoyou 1052, the male parent C52 has a sowing period of 110 days, and the female parent 105A has a sowing period of 105 days. The male parent has a long sowing period. Combined with the local climate conditions in Liaoyang, the rainy season is in late July. It can be determined that the male parent can avoid the rainy season by sowing after April 20. According to the sowing date of the parental parent, combined with the sowing test in stages over the years, it can be determined that the sowing date of the female parent is 10 days later than that of the male parent, and the sowing date will be on April 30.
