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 businessmen to take risks
On the other hand, most of the local purple-black rice varieties in my country are glutinous rice. Even if there are local purple-black rice sticky rice varieties, or even a new purple-black rice sticky rice variety bred, not only the yield is low, but also due to insufficient amylose content, it is difficult to To meet the demand for high-quality raw materials in purple and black rice noodle processing

Embodiment 1

[0046] Example 1 Screening of high-combining ability aromatic purple hard rice gene donor resources

[0047] The flow chart of the two-line hybrid rice selection of aromatic purple hard rice special for processing purple fragrant rice noodles by conventional breeding in the present invention is shown in figure 1 , In which the "high-combining ability aromatic purple hard rice variety I × two-line sterile line II" is marked as "mutual parental parent" means that the high-combining ability aromatic purple hard rice variety I can be used as the female parent. Two-line sterile line II is used as the male parent to cross, or two-line sterile line II is used as the female parent, and the high-combining ability aromatic purple hard rice variety I is the male parent. The same applies to rice variety IV×two-line restorer line V".

[0048] If the two-line hybrid rice selection of aromatic purple hard rice of the present invention is combined with biotechnology, it is: using conventional biot...

Embodiment 2

[0055] Example 2 Creation of two-line sterile line Wenzi 846S with aromatic purple hard rice

[0056] In this example, Wenzi 820 is used as the gene donor of fragrance, purple rice, and hard rice of the present invention-high combining ability aromatic purple hard rice rice variety I, and the excellent two-line sterile line Pei'ai 64S is used as nuclear male sterility. Gene donor material-two-line sterile line II, according to figure 1 Breeding two-line sterile line III with high combining ability and aromatic purple hard rice, specifically:

[0057] In August 2008, in the experimental base of the State Academy of Agricultural Sciences in Wenshan City, Yunnan, the female parent was Peiai 64S and Wenzi 820 was the male parent. The aroma gene a, purple rice gene P and hard rice gene H were introduced into the In the excellent two-line sterile line of nuclear male sterility genes, the fragrance, purple rice and hard rice genes and nuclear male sterility genes are integrated. Afterwar...

Embodiment 3

[0062] Example 3 Establishment of Wenzihui 8739, a restoration line of aromatic purple hard rice

[0063] In this example, Wenzi 790 was used as the gene donor variety of fragrance, purple rice, and hard rice of the present invention—high-combining ability aromatic purple hard rice rice variety IV, and Yihui 1577 was used as the strong restoring gene donor material—two Department to restore Department V, follow figure 1 Breeding two-line restorer line VI with high combining ability and aromatic purple hard rice, specifically:

[0064] In August 2008, in the experimental base of the State Academy of Agricultural Sciences in Wenshan City, Yunnan, the fragrant purple hard Miwen purple 790 was used as the female parent, and the excellent restorer line Yihui 1577 with high combining ability, wide adaptability and hard rice quality was used as the father. In this hybridization, according to the breeding goals of rice grains with strong flavor, purple rice, and hard rice, the pedigree met...

Abstract

The invention discloses a method for breeding flavor-type purple hard rice two-line hybrid rice special for processing fragrant purple rice noodles. The method particularly comprises the following steps: screening a high-combining ability purple hard rice variety I and a high high-combining ability flavor-type purple hard rice variety IV, wherein the variety I and the IV have different genetic backgrounds and comprise purple rice genes P with a dosage effect and allelic fragrance genes a and allelic hard rice genes H; and respectively introducing the fragrance genes a, the purple rice genes P and the hard rice genes H in the two varieties into a two-line sterile line I and a two-line restoring line V, so as to respectively obtain a high-combining ability flavor-type purple hard rice two-line sterile line III and a high-combining ability flavor-type purple hard rice two-line restoring line VI, hybridizing and assembling, so as to obtain flavor-type purple hard rice two-line hybrid rice VII special for processing the fragrant purple rice noodles. The flavor-type purple hard rice two-line hybrid rice VII processed from the flavor-type purple hard rice bred by the method in the invention is fragrant and is high in yield and wide in adaptability, and seed coats are purple; and the rice noodles processed from the hybrid rice is boilproof, purple, has a slight fragrance and good taste and is low in fracture rate.

Description

Technical field [0001] The invention relates to hybrid rice breeding technology, in particular to a method for breeding two-line hybrid rice with aromatic purple hard rice specially used for processing purple fragrant rice noodles. Background technique [0002] With the development of urbanization, environmental degradation 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 has been increasing, and is in the sub-region. The proportion of people in healthy state is increasing, and about 45% of people in the country are in sub-health state. This has not only brought tremendous pressure to the medical system of the country and society, but also brought unspeakable pain to people. People’s demand for food functionality is getting higher and higher. Food is more concerned and loved. Especially as our country enters an aging society, th...
