The invention discloses a breeding method for cultivating an indica type three-line strong high-quality restoring line in multiple
tiller positions. The method comprises the following steps of: (1) selecting one of parents with more than or equal to 18
main stem total leaves, taking the parent as a female parent set, and preparing an Fe generation; (2) selecting an individual
plant which has more than or equal to 18
main stem leaves, excellent comprehensive agricultural shape and moderate growth period from an F2 separation generation; and (3) planting the selected individual
plant according to the strain, screening from 3-5 generations to obtain a new strain, performing continuous combining ability measurement and leaf age observation in 2-3 years on a stable strain with more than or equal to 18
main stem total leaves by using Zhenshan 97A, and integrating the results to obtain the indica type three-line strong high-quality restoring line. The obtained indica type three-line strong high-quality restoring line has more than or equal to 18 main stem total leaves, multiple
tiller positions, high primary
tiller rate, early tiller and early
germination, a foundation is laid for obtaining full and
large ears, the total spikelet number in unit area of the restoring line can be effectively increased, and a guarantee is provided for obtaining high per unit area yield.
