Problems solved by technology

The main reasons for these problems are that my country does not pay enough attention to rice varieties for special rice noodle processing, and the research and development is insufficient. There are very few high-amylose rice varieties that are suitable for processing high-quality rice noodles. Without the demand for rice noodle processing, the price of rice noodle rice also remains high, leading unscrupulous busin...

Embodiment 1

[0043] Example 1 Screening of aromatic purple hard rice resources

[0044] The flow chart of the present invention is to carry out the selection and breeding of fragrant purple hard rice three-line hybrid rice by conventional breeding. Such as figure 1 As shown, the mark "can be the parents of each other" in the place of "aroma type purple hard rice rice maintenance variety I × rice maintenance line II" means that the fragrant type purple hard rice rice maintenance variety I can be used as the female parent, and the rice maintainer line can be used as the female parent. II is the male parent hybrid, or the rice maintainer line II can be used as the female parent, and the aromatic purple hard rice rice maintainer I can be used as the male parent. "Aromatic purple hard rice rice restorer variety VI×rice restorer line VII" is hereby analogy.

[0045] If the fragrant type purple hard rice three-line hybrid rice breeding of the present invention is carried out in combination with...

Embodiment 2

[0053] Example 2 Establishment of fragrant purple hard rice maintainer line Wenxiangzi 695B and sterile line Wenxiangzi 695A

[0054] In this embodiment, Wenzi 488 is used as the gene donor of aroma, purple rice, and hard rice of the present invention——aroma type purple hard rice rice maintenance variety I, and Gang 46B is used as a high combining ability and strong maintenance gene donor material—rice The maintainer line II, with the sterile line II-32A as the three-line sterile line IV, according to figure 1 Breeding of fragrant purple hard rice maintainer line III and fragrant purple hard rice male sterile line V, specifically:

[0055] In March 2007, Wenzi 488 was used as the female parent and Gang 46B was used as the male parent in the network room of Wenshan Prefecture Academy of Agricultural Sciences in Sanya City. Afterwards, according to the breeding goals of fragrant rice, purple rice, hard rice, etc., using The pedigree method and the method of increasing the selec...

Embodiment 3

[0061] Example 3 Establishment of Wenzihui 856, a restorative line of fragrant purple hard rice

[0062] In this example, Wenzi 548 is used as the gene donor variety of aroma, purple rice, and hard rice of the present invention—the recovery variety VI of fragrant purple hard rice rice, and Jianghui 151 is used as the gene donor material of strong recovery and high combining ability— Rice restorer line VII, according to figure 1 Breeding of fragrant purple hard rice restorer line VIII, specifically:

[0063] In July 2008, Wenzi 548, a fragrant purple hard rice variety, was used as the female parent in the network room of Wenshan Prefecture Academy of Agricultural Sciences, Wenshan City. Jianghui 151 was used as the male parent for hybridization, and then according to the breeding goals of rice grains with strong aroma, purple rice, and hard rice, the pedigree method and the method of increasing selection pressure were used to identify the aroma of brown rice and observe the pu...

Abstract

The invention discloses a breeding method for fragrant purple hard rice three-line hybrid rice for processing purple fragrant rice noodles. The breeding method includes the following steps that 1, a fragrant purple hard rice maintaining variety containing purple rice genes P with the dosage effect, allelic fragrance genes a and allelic hard rice genes H and a fragrant purple hard rice restoring variety containing purple rice genes P with the dosage effect, allelic fragrance genes a and allelic hard rice genes H; 2, the fragrant purple hard rice maintaining variety is bred to obtain a fragrant purple hard rice maintenance line with the gene type of aaPPHH and a fragrant purple hard rice male sterility line with the gene type of aaPPHH; 3, the fragrant purple hard rice restoring variety is bred to obtain a fragrant purple hard rice restoring line with the gene type of aaPPHH; 4, the fragrant purple hard rice male sterility line serves as a female parent, the fragrant purple hard rice restoring line serves as a male parent, and the fragrant purple hard rice hybrid rice with the high yield, the wide application range and the gene type of aaPPHH is obtained through matching. The bred fragrant purple hard rice hybrid rice is fragrant in flavor and high in yield, seed coats are purple, and the processed rice noodles are low in breaking rate and good in cooking performance and mouthfeel.

Description

technical field [0001] The invention relates to hybrid rice breeding technology, in particular to a method for breeding fragrant purple hard rice three-line hybrid rice for processing purple fragrant rice noodles. Background technique [0002] With the development of urbanization, environmental deterioration and changes in people's lifestyles, especially changes in dietary structure, the incidence of various modern chronic diseases such as atherosclerosis, hyperlipidemia, coronary heart disease and cancer continues to rise. The proportion of people in a healthy state is increasing, and about 45% of the people in the country are in a sub-healthy state. This has not only brought enormous pressure to the medical system of the country and society, but also brought unspeakable pain to people. People have higher and higher demands for food functions, and they are more and more interested in foods that have both nutrition and medicinal health functions. Food gets more attention an...
