Process for breeding green health-care tree-rice

Abstract

The invention provides a method for breeding green and health- care rice. The method employs wild bamboo, health- care rice, antihypelipidemic rice and purple blood glutinous rice for multiple hybridization and backcross, and selects out variety of genetic stable and good farming description. The invention combines favorable description of high- output and health-care to culture new variety with heterosis, which is characterized by fast growth, strong tillering property, generally there are 106 tillers, and there are also tillering in tillering branch, disease- resistant, lodging resistant and suitability of different environment.

Description

technical field [0001] The invention belongs to the field of plant breeding, and in particular relates to a breeding method of green health-care tree rice. Background technique [0002] Rice is one of the main food crops of human beings. With the continuous growth of the global population and the continuous enhancement of people's health awareness, people need more health food. However, the cultivated land is decreasing. Therefore, people are eager to use ordinary rice to Produce high-yield health food. Breeding new varieties with greater potential for increasing yield is a valuable and efficient way to increase yield per unit area. Humans discovered rice at the source of the Yangtze River 5,000 years ago. At 24° north latitude, wild rice was found in Xianrendong, Wanwan Mountain, Jiangxi, in Southeast Asia. It grows in the middle and lower reaches of the Yangtze River. Two major breakthroughs were made. One was the breakthrough in dwarf breeding from the late 1950s to the...

Problems solved by technology

However, the rice yield of the two major breakthroughs has been hovering. In 1981, Japan first proposed rice super-high-yield breeding. In 1989, the International Rice Research Institute officially launched research on rice super-high-yield breeding. my country launched the "China Super Breeding" program in 1996. , using the ideal plant type to shape the heterosis between indica and japonica subspecies, and using the technical route of combining and improving quality and resistance. After the cooperation of scientific research workers across the country, in 2000, the average yield of 667 square meters reached 700 The goal of the first phase of the kilogram, and in 2004 in Hunan in 2004 achieved the second phase goal of an average yield of 667 square meters to reach 800 kg, and proposed that my country's super rice should achieve an average yield of 667 square meters to reach 900 kg in 2010 The second phase of the goal, so far, Chinese breeders have not yet developed ultra-high-yielding and green health-care rice
