Abstract

The invention discloses a breeding method of a purple-leaf black japonica fragrant rice variety, and belongs to the technical field of crop genetic breeding. According to the method, a large, full and fragrant rice variety A, anelliptical carmine rice variety B and a black rice variety C with purple auricle and leaf ligule and black japonica are taken as parents, excellent character polymerization is realized by adopting pedigree method selection and a character identification technology through hybridization and multiple-cross methods, and the new purple-leaf black japonica fragrant rice variety is obtained. The obtained purple-leaf black japonica fragrant rice variety is high in appearance ornamental value, high in yield, good in resistance and wide in application range, black japonica brown rice is full, compact and fragrant and has extensibility after being cooked, and the rice is good in taste, resistant to rice plague and high in market value and is expected to be applied to large-area production in rice areas.

Description

technical field [0001] The invention belongs to the technical field of crop genetics and breeding, and in particular relates to a breeding method of purple leaf black japonica rice. Background technique [0002] With the continuous improvement of people's living standards, the nutritional health and added value of rice have become the main research direction of rice breeding under the premise of ensuring rice yield. Compared with ordinary rice, purple leaf black japonica rice is rich in protein, amino acid and fatty acid, and rich in trace active elements such as iron, zinc, copper, manganese, etc. Physiological functions such as iron anemia, anti-stress response and immune regulation function. At the same time, the large purple-leaf rice fields have a very high ornamental value. Therefore, it is of great significance to carry out breeding and popularization of new varieties of high-quality functional rice for the production of high-quality functional rice and the improvem...
