Embodiment 1
[0032] Example 1: Shanyou 63 was used as the female parent, and Ganyouwan 9 was used as the recurrent male parent. In the B4F3 generation, a restorer line Huiganyouwan 9 with agronomic traits similar to Ganyouwan 9 and carrying a wild-type restorer gene was bred. Zhenshan 97A and Huiganyouwan 9 were used to form Shanyouhuiganyouwan 9.
Embodiment 2
[0033] Example 2: Shanyou 63 was used as the female parent, and Feng Liuzhan was used as the reincarnated male parent. In the B3F3 generation, a restorer line Huifengliuzhan with agronomic traits similar to Fengliuzhan and a wild-type restorer gene was bred. Use Zhenshan 97A and Huifeng Liuzhan to form Shanyou Huifeng Liuzhan.
Embodiment 3
[0034] Example 3: Shanyou 64 was used as the female parent, and Jiafuzhan was used as the reincarnated male parent. In the B3F3 generation, a restorer line Huijiafuzhan with agronomic traits like Xijiafuzhan and a wild-type restorer gene was bred. Use Zhenshan 97A and Huijiafuzhan to form Shanyouhuijiafuzhan.
