Embodiment Construction

[0055] , Yuncai No. 1 multicolored rice breeding method

[0056] In a paddy field at an altitude of 1200-1900 meters, the indica white rice variety A type is used as the female parent, and the japonica colored rice variety Lijiang Xiaoheigu is used as the male parent. Seed coat color mode RGB, R43, G18, B22 artificial emasculation pollination hybridization, according to the breeding objectives, adopt the method of combining pedigree selection and color mode RGB selection to breed indica and japonica subspecies colorful rice with the same quality and agronomic performance , the brown rice colors of colorful rice are black, brown, red, yellow, and white. The breeding objectives are as follows: the appearance of brown rice is black, tan, red, yellow, and white; the appearance of polished rice is transparent; the agronomic traits are: compact plant type, ear length of more than 20 cm, and the total number of grains per ear is 120-150 grains / ear , tillering at least 10 per hole, ...

Abstract

The invention relates to a breeding method of five-color rice. According to the breeding method, indica type white rice variety type A or Deyou 17 is used as female parents, stem type colorful rice variety Lijiang small millet is used as male parents, artificial castration pollination and hybridization is carried out, according to the seedling target, pedigree method breeding and color mode RBG (red, blue and green) selection are combined, indica and stem subspecies colorful rice with the basically identical agronomic characters including the strain height, the growth period and the like and different rice seed coat colors are obtained through seven-year and six-generation breeding, and the coarse rice colors of the five-color rice are respectively the black, the sepia, the red, the yellow and the white. The same-field planting of the rice with five colors is realized, the labor and the time are saved, the planting cost is identical to that of the conventional rice, and the yield is higher than that of other colorful rice. The five-color rice is used as the special rice, the nutrition value of the five-color rice is much higher than the ordinary rice, the market value is higher than that of the ordinary rice, and better industrial development prospects are realized.

Description

technical field [0001] The invention relates to a new rice variety and a breeding method thereof. Specifically, it is a multicolored rice and a breeding method thereof. Background technique [0002] Among the rich and diverse rice germplasm resources in my country, there are precious colored rice resources. In terms of the color of the seed coat, it can be divided into purple rice or black rice, red rice, yellow rice and green rice. Rice and red rice are the most common. Colored rice is mainly distributed in the Yunnan-Guizhou Plateau and South China, among which Yunnan, Guangxi, Hunan, and Guizhou provinces are the majority, followed by Guangdong, Jiangxi, Hubei, and Jiangsu provinces. Among them, black rice varieties are mainly distributed in Yunnan, Guizhou, Guangxi, Guangdong and other provinces. There are many colors such as purple black and black; red rice is mostly concentrated in Yunnan, Guangxi, Hunan, Guizhou, Guangdong, Jiangxi and other provinces, and most of t...
