Embodiment 1
[0023] Example 1 A rice rapid aggregation breeding method based on the targeted target rice key variety "Yangdao No. 6"
[0024] The rice breeding materials used in Example 1 are: the backbone variety "Yangdao No. 6" and its mutation-resistant mutant "Zhemidao No. 1", the tall and strong stem mutant "Zhedao No. 1", Insect mutant "Zhe Kangdao No. 1" and multi-tiller mutant "Zhe Duo Pai Dao".
[0025] Among the corresponding breeding materials, "Yangdao 6" was bred by Jiangsu Lixiahe Regional Agricultural Science Research Institute, and passed the approval of Jiangsu, Anhui and Hubei Crop Variety Approval Committees in 1997, 2000, and 2001. Prominent mid-indica late-maturing conventional rice varieties can be purchased from Jiangsu Lixiahe Academy of Agricultural Sciences.
[0026] The disease-resistant mutant "Zhemidao No. 1" is a mutant with extremely compact plant type and strong resistance to sheath blight, which was selected by the mutation of "Yangdao No. 6" of Zhejiang U...
Embodiment 2
[0045] Example 2 A rice rapid aggregation breeding method based on the targeted target rice key variety "Zhehui 7954"
[0046] The rice breeding materials used in this example are: the backbone variety "Zhehui 7954" and its quality mutant "Zhefu 111" produced by mutagenesis, the long-grain mutant "Zhehui 7954-LG2", and the large-grain mutant "Zhehui 7954-LG2". Hui 7954-BG3" and the late-maturing mutant "LR7954".
