Abstract

The invention discloses an efficient breeding method for high-quality millet, which aims at solving the problems of traditional millet breeding and comprises the steps of parent selection and matching, planting layout, spike cutting and size thinning, bagging and pollination, generation selection and the like. The parent selection follows the principle of matching and complementation of recessive and dominant characters, a planting mode of'double male parents and female parents' is adopted, and the sowing time is adjusted. Middle grain sizes are reserved by cutting ears and thinning, and flapping pollination is performed at a specific time period after bagging. And performing rice color quantitative selection by combining generation selection with phenotype observation and ABL value measurement by a colorimeter. The multi-generation selection strategy covers from the F1 generation to the F5 generation, and all the generations are screened according to character characteristics. According to practice, the pollination success rate of the method is larger than or equal to 80%, the rice color quantitative selection accuracy rate exceeds 90%, 22 high-quality varieties such as' Jinzhu K1 'and the like are bred, the popularization benefit reaches 18.24 billion yuan, and the method has the advantages that time and labor are saved, the quality identification cost is low, the breeding period is short and the like, and is suitable for large-scale high-quality millet breeding.
