Abstract
The invention discloses an application of a partially indica-type paddy rice dominant dwarf mutant and belongs to the technical field of crop breeding. In the invention, natural mutation of genome of paddy rice, namely, a dominant dwarf mutant plant, is employed to obtain a stable and pure dominant dwarf mutant material through pollen tissue cultivation, thereby providing a dwarf source for breeding two-line or three-line hybridized paddy rice varieties. The selected dominant dwarf mutant can significantly reduce plant height of paddy rice, can improve anti-lodging performance and stable yield, and increases possibility of selecting an inter-subspecific hybridization variety and further provides substance conditions of increasing yield of the paddy rice and converting farming modes. With the stable and pure dominant dwarf material, a system being capable of randomly grouping and selecting the dwarf hybridization paddy rice varieties is established, by which the lodging problem, which often occurs during production, is solved. Meanwhile, the dominant dwarf mutant is suitable for a simplified cultivation mode in production of hybridized seeds and in large field, and can reduce labor intensity and production cost.
Description
Technical field
The invention belongs to rice breeding technology field, be specifically related to a kind of application of indica-tendency type rice dominant dwarf mutant.
Background technology
Plant height is the Main Agronomic Characters relevant to output, according to the plant height of rice maturity, usually paddy rice is divided into high stalk, semi-dwarf mutant and three types of short stem, plant height exceed certain limit easily cause lodging and the underproduction, of short stem be not only conducive to resistant to lodging, and impoverishment tolerant, be conducive to improving output.The breeding wheat for semidwarfness that late 1950s starts, makes Plant Height of Rice be reduced to semi-dwarf mutant, and rice yield obtains first time leap, one of significant achievement becoming " green revolution ".Current ongoing Super rice breeding mainly utilizes ideotype and subspecies indica and japonica hybrid advantage to be further enhanced to rice yield.
At present, long-grained nonglutinous rice breeding mostly utilizes sd-1 Semi dwarfism gene, is also much to import sd-1 gene by indica-japonica hybrid in japonica rice breeding of short stem, or utilizes the short source of japonica rice with sd-1 gene.The Reusability of same gene, by causing, the hereditary basis of improved variety is narrow, and hereditary fragility will increase.And the dwarf gene utilized in rice breeding is all recessive gene, in breeding of hybridized rice, the use of Recessive dwarf genes often requires that parents must have same dwarf gene, which limits and select favourable parent in resource widely.If but utilized indication law, then Rice Germplasm Resources could be made to be used more effectively and to shorten breeding time.Therefore new Plant Height of Rice controlling gene particularly indication law is excavated, significant to improving rice yield further.
Make full use of the merits such as the nanism of dominant dwarf and binding molecule marker assisted selection means, male sterile line and the restorer of dominant Dwarfing gene are carried in seed selection, innovation breeding material, to improveing the plant height of existing hybrid rice variety, improves the anti-fall performance of hybrid rice variety.
Summary of the invention
Technical problem
At present the Rice Dwarf key-gene of extensive use can only have sd-1 aborning, and the key-gene of short stem of other type or with bad gene close linkage, or with other bad proterties, as grown thickly, thin stalk, dew joint, granule etc., all do not obtain aborning and effectively utilize, the object of this invention is to provide indica-tendency type rice dominant dwarf, its nanism and other excellent economical characters can be made full use of, and binding molecule marker assisted selection means, seed selection is carried three of dominant Dwarfing gene and is or two is restorer and male sterile line, to improveing the plant height of existing hybrid rice variety, improve the anti-fall performance of hybrid rice variety.
Technical scheme
A kind of application of indica-tendency type rice dominant dwarf mutant, it is characterized in that, this indica-tendency type rice dominant dwarf mutant is dominant short bar sd-y, paddy rice (Oryzasativa), preservation is carried out at China Committee for Culture Collection of Microorganisms's common micro-organisms center on May 7th, 2015, Yard 1, BeiChen xi Road, Chaoyang District, Beijing City, address institute of microbiology of the Chinese Academy of Sciences, preserving number is CGMCCNO:10593.
Described dominant short bar sd-y can be for two or the cultivation of series of three-series hybrid rice kind provides the application in short source.With dominant short bar sd-y for male parent, recover to be male parent with rice male, the plant height of improvement rice restorer.
Described dominant short bar sd-y can application in the production of hybrid seeds or the light simple cultivation mode of Production of Large Fields, or is applied in raising hybrid rice lodging resistance kind.
Beneficial effect
The lodging sex chromosome mosaicism of rice varieties is own through becoming the important limiting factor of Rice Production and rice variety selective.Lodging not only causes Yield of Rice Varieties to decline, but also causes the change of rice quality bad.Affecting among the relevant factors of the anti-fall property of rice varieties, plant height is one of most important factor.
The indica type dominant dwarf sd-y of institute of the present invention seed selection shows dwarfing (Fig. 1) from seedling stage, performance in tillering stage is downgraded and is tillered and increases (Fig. 2), be only as 49.27cm to maturing stage sd-y plant height, less than the half (Fig. 3) of wild type plant height 98.47cm.Except Dwarfing phenotypes, also performance blade is dark green increases with tillering.Tillering time ripe is approximately 1.4 times of wild type.Compared with wild type, each internode shorten in average of sd-y is the mutant of dn type.
With the indica type dominant dwarf sd-y of institute of the present invention seed selection for maternal (plant height 49.27cm), be about 100cm with the plant height that Dular, Kasalath, Kui rice, KN configure hybrid combination for male parent, plant height reduces amplitude and about reaches 50%.
The present invention utilizes the japonica rice line carrying dominant dwarf rice mutator gene to carry out artificial hybridization from different parent materials, effectively can reduce the plant height of the hybrid rice of institute's seed selection, improving the lodging resistance of the hybrid rice of institute's seed selection, is the resources approach that the super close problem exploration of plant height in solution rice varieties and subspecies high yield and Breeding For Super High-yielding process is new.
