Problems solved by technology

However, the varieties obtained by these breeding methods have low yields and cannot meet market consumption needs, especially no fragrance, high amylose content, reversion after cold, poor eating taste, and mostly eaten while hot, so as not to harden after cold, Difficult to digest, especially those with poor gastrointestinal function, or the elderly dare not eat more, forming an embarrassing situation that they dare not eat good things often

Embodiment 1

[0043] Example 1 Screening of aromatic red soft rice resources

[0044] The flow chart of the present invention is to carry out the selection and breeding of fragrant red soft 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 "fragrant red soft rice variety I×rice maintainer line II" means that the fragrant red soft rice 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 red soft rice rice maintainer I can be used as the male parent. "Aromatic red soft rice rice restorer variety VI × rice restorer line VII" is hereby analogy.

[0045] If carry out the three-line hybrid rice selection of fragrant red soft rice of the present invention in conjunction with biotechnology, then be: utilize conventional biotechnological means,...

Embodiment 2

[0053] Example 2 Creation of Wenxianghong 964B and Wenxianghong 964A CMS line of fragrant red soft rice

[0054] In this embodiment, Wenhong 618 is used as the gene donor of aroma, red rice, and soft rice of the present invention—the fragrant red soft rice rice maintenance variety I, and Wenxiang 28B is used as the gene donor material with strong combining ability and retention—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 red soft rice maintainer line III and fragrant red soft rice male sterile line V, specifically:

[0055] In July 2008, Wenhong 618 was used as the female parent and Wenxiang 28B was used as the male parent in the network room of the Wenshan Prefecture Academy of Agricultural Sciences in Wenshan City. After that, the rice grains were considered to have fragrance, red rice, soft rice, high combining ability, and The breeding goal of maintaining ability is more preferably...

Embodiment 3

[0061] Example 3 Creation of Wenhonghui 628, a restorative line of fragrant red soft rice

[0062] In this example, Wenhong 397 is used as the gene donor variety of aroma, red rice, and soft rice of the present invention—the restoration variety VI of fragrant red soft rice rice, and Wenhui 206 is used as the gene donor material of strong restoration and high combining ability— Rice restorer line VII, according to figure 1 Breeding of fragrant red soft rice restorer line VIII, specifically:

[0063] In July 2008, Wenhong 397, a fragrant red soft rice variety, was used as the female parent in the network room of Wenshan Prefecture Academy of Agricultural Sciences in Wenshan City. The restorer line Wenhui 206 is used as the male parent for hybridization, and then the breeding goals are based on fragrance type, red rice, soft rice, high combining ability, and resilience, and more preferably have slender grains, large spikes, large pollen volume, and long flowering period, etc. F...

Abstract

The invention discloses a breeding method for aromatic red soft rice three-line hybrid rice. The method comprises the steps of: 1) screening an aromatic red soft rice maintenance variety and an aromatic red soft rice recovery variety that contain a red rice gene R having dose effect, and also contain an allelic aromatic gene a and an allelic soft rice gene s; 2) subjecting the aromatic red soft rice maintenance variety to breeding to obtain an aromatic red soft rice maintenance line and an aromatic red soft rice male sterile line with a genotype of aaRRss; 3) subjecting the aromatic red soft rice recovery variety to breeding to obtain an aromatic red soft rice recovery line with a genotype of aaRRss; and 4) taking the aromatic red soft rice male sterile line as the female parent, and adopting the aromatic red soft rice recovery line as the male parent to produce the aromatic red soft rice hybrid rice with high yield and wide adaptability. The aromatic red soft rice hybrid rice bred by the method provided by the invention has heavy aroma, red rice seed coat and high yield, also the steamed rice is soft and moist, does not retrograde, and can be edible when it is cold and hot.

Description

technical field [0001] The invention relates to hybrid rice breeding technology, in particular to a method for selecting and breeding aromatic red soft rice three-line hybrid rice. Background technique [0002] Red rice refers to the accumulation of anthocyanin or anthocyanin in the seed coat and pericarp of rice, which makes brown rice appear red and other colors. Therefore, it is also called medicinal rice, blood-enriching rice, moon rice, longevity rice, tribute rice and pearl rice. "Compendium of Materia Medica" records that "red rice has the effects of nourishing yin and tonifying kidney, invigorating spleen and warming stomach, improving eyesight and promoting blood circulation". Test reports, red rice is rich in trace elements such as zinc, copper, iron, selenium, molybdenum, calcium, manganese, etc., the content is 0.5-3 times higher than that of ordinary rice, and also contains flavonoids, alkaloids, phytoziols and carotene, etc. Pharmaceutical ingredients, these ...
