Example Embodiment

[0034] Example 1 Screening of donor varieties with specific recessive gene for glume color

[0035] In this example, the excellent maintainer lines of aromatic soft rice Haoxiang 24B, Wenxiang 28B and restorer lines Wenhui 206, Wenhui 247, Yihui 1577, etc. were used as the male parent (as the rice variety II of the present invention). Ha, Red Shell Red Nuo, Purple Valley, Hao Nuodian, Hao Leng, La Shuo, Hao Kang, Hao Mu Liang, Hao Zhao, Yuanyang Red Rice, Myanmar Yellow Board, Hao Pi, Da Zi Rod, Huang Hu Xiang , Thai jasmine, Kaogang, Gehe, Shandongba, Qiba, Hao Da Da Nong, Hao Mu Yun, Hao Mu Lu, Hao Mu West, Lijiang Xintuan Black Valley, Lijiang Pantian Black Valley, Ninglang Laoya Valley , India Dular, etc. as the female parent (as the rice resource variety I with the darker glume color of the present invention), in July 2004, the cross-matching group in the courtyard room of Wenshan City, Yunnan Province, obtained 140 hybrid F 1 Combine seeds.

[0037] Example 2 Breeding of lines with two-color glumes marker

[0038] In this example, Burma yellow board was used as the hull color-specific recessive gene donor variety III of the present invention, and a restorer line with high resistance to rice blast, excellent plant type, and strong combining ability with a dark brown genetic background of Yunnan hull is suitable Hui 1577 is a rice resource variety IV with a dark brown genetic background of Yunnan glumes. The strain VI with two-color glumes was selected and specifically:

[0039] In April 2005, at the experimental base of the Wenshan Academy of Agricultural Sciences in Sanya, the Huangban Institute was used as the female parent and Yihui 1577 was used as the male parent for crossbreeding, and then at the experimental base of the Wenshan Academy of Agricultural Sciences in Wenshan City, Yunnan Province and Wenshan Sanya, Hainan The experimental base of the State Academy of Agricultural Sciences uses pedigree methods and met...

[0041] Example 3 Breeding of line VII with bicolor glumes

[0042] In this example, 14 strains with ochre-yellow husk traits selected in Example 2 were used as the line VI with bicolor glumes of the present invention, and the line VII with bicolor glumes was selected, specifically:

[0043] In May 2008, 14 strains with ochre-yellow glumes were selected from the Sanya test base. They were located in Wenshan, Luoping, Jinghong, Longyang, Binchuan in Yunnan, and Guiyang and Sichuan in Guizhou. 8 different ecological regions, including Jiangyou and Guanghan, conducted multi-point identification tests. In the experiment, the hybrid male parent Yihui 1577 and Yunnan aromatic soft rice conventional rice variety Diantun 502 were used as controls. Each plot was 0.02 mu and 360 clusters were planted in each plot. Single planting was performed without duplication. At maturity, the species were tested according to their regularity, resistance to rice blast, plant height, effective panicle per...

Abstract

The invention discloses a method for breeding rice with recessive two-color glume markers. The method includes the following steps that 1, a glume color specific recessive gene donor variety is selected from deep-glume-color rice varieties; 2, after the glume color specific recessive gene donor variety and a rice variety with a Yunnan glume black brown genetic background are hybridized, multi-generation selfing is performed, and a strain with two-color glumes is obtained through breeding; 3, the strain with the two-color glumes is subjected to a multi-point test and a stability test, and a strain which is stable in character, high in resistance and high in adaptability and is provided with the two-color glumes is selected; 4, the strain VII with the two-color glumes and a variety with the normal glume color are hybridized, and the rice with the recessive two-color glume markers is obtained through identification and breeding. According to the method for breeding the rice with the recessive two-color glume markers, a rice recessive special color glume marker gene excavation channel can be expanded.

Description

technical field [0001] The invention relates to rice breeding technology, in particular to a method for breeding rice with recessive double-color glume markers. Background technique [0002] Rice is the main crop in the world, and it is also the most important food crop in my country. More than half of the world's population uses rice as a staple food, and it is as high as 60% in China. Therefore, the status of rice technology innovation has attracted great attention from the world. Rice hull color is an important marker trait of rice, which can stabilize genetic traits, is less affected by the environment, and can be visually identified after heading. In the process of rice seed production and commercial development, especially in the commercial seed production and In the process of mechanized seed production, it has very special significance. Excavating exclusive and proprietary seeds with intuitive and special marks with independent intellectual property rights will help...
