Breeding and High-Yield Cultivation Techniques of the Rice Variety Lindao 12
1 Breeding history: In 1999, the Linyi City Rice Research Institute used radiation mutation breeding, treating 500 g of Yujing 6 seeds with 60Co alpha-rays at a dose of 40,000 roentgens, and planted the Mo generation that year; the population showed high sterility, and all seeds (M1 generation) were harvested in autumn; in the winter of the same year, winter multiplication in the south was carried out to add a generation, planting the M1 generation, and the population showed high segregation, and all M2 generation seeds were harvested. In 2000, the quartering bulk breeding method was used, planting the M2 generation, and in autumn superior plants were selected from the mutant population.
