The invention discloses a cultivation method for a high-yield
japonica rice variety with a good taste. On the basis of a high-yield
disease-resistant breeding method, by using a chalkiness observation device, a near-
infrared quality analysis and determination device and a
rice grain taste analyzer,
staring from selection of a parent, high-quality
japonica rice varieties which are excellent in quality, and contains 6%-9% of
rice grain protein and 12%-20% of
amylose in Lingshui, Hainan and the lower-middle reaches of yangtze river basin are selected as female parents, the female parent are hybridized with mainly-popularized
japonica rice varieties which are used as male parents and produced in the same period, starting from F2, the
protein content and
amylose content are used as selection pressure, rice grains containing 6%-9% of
protein and 15%- 20% of
amylose are selected, starting from F3, the chalk white rate and chalkiness degree are used as selection pressure, and single plants with the chalk white rate smaller than 30% and chalkiness degree smaller than 5% are selected, so that high-yield
disease-resistant
japonica rice new strains with excellent appearance and taste can be conveniently cultivated directionally; by adopting the cultivation method disclosed by the invention, the cultivated
japonica rice variety has quality environment insensitivity, is stable among years and is unlikely to influence by temperature and light conditions.
