Abstract
The invention discloses the selection of a kind of high resistance naked body yellow leaf Characters of Giant Embryo Rice CMS line, belong to Special Rices breeding technical field.This method selects yellow leaf marker parent, drought resisting parent, naked body rice parent, blast resisting parent is hybrid strain, Characters of Giant Embryo Rice three is maintainer geB is recurrent parent, naked body will be controlled by hybridizing the polymerization that backcrosses, Huang Ye, drought-resistant, the gene pyramiding of these 4 kinds of proterties of blast resisting is in maintainer to Characters of Giant Embryo Rice three, being bred as agronomy is that maintainer geB is highly consistent with yield traits and former Characters of Giant Embryo Rice three, there is naked body, Huang Ye, drought-resistant, the giant embryo three of blast resisting characteristic is maintainer (anti-yellowing smooth geB), anti-yellowing smooth geB is hybridized and 3 generations that backcrossed with corresponding Characters of Giant Embryo Rice male sterile line, incubation has naked body, Huang Ye, drought-resistant, the giant embryo CMS line (anti-yellowing smooth geA) of blast resisting characteristic, anti-yellowing smooth geA has better resistance, male sterile line purity is high, the advantages such as easy harvesting.
Description
Technical field
The present invention is specifically related to the selection of a kind of high resistance naked body yellow leaf Characters of Giant Embryo Rice CMS line, belongs to Special Rices breeding technical field.
Background technology
Recessive leaf colour marker yellow leaf marker imports male sterile line and is used for auxiliary impurity elimination, is the effective way improving hybrid purity.Breeder utilizes male sterile line seedling to carry yellow leaf marker, and the hybrid F of its preparation
1the characteristic of green of acting normally again, at F
1seeding stage mixes male sterile line wherein or maintainer rice shoot according to the different rejecting of leaf aberration, thus reaches impurity elimination pure keeping object.Naked body rice is the paddy rice of whole body without hair, because sick worm not easily adheres to and invades, performance has stronger resistant to diseases and insects, skin can be reduced itch and damage to skin when manual harvesting and threshing, be easy to mechanized harvest, add free from dust in man-hour, can environmental pollution be reduced, so also known as " environmental protection paddy rice ".Characters of Giant Embryo Rice is a kind of paddy rice with large prostate, make the nutritive value of rice greatly improve because of the increase of embryo, containing abundant natural nutrition element and the physiological activator such as γ-aminobutyric acid, protein and several mineral materials, amino acid, vitamin, normal food can improve health, and regulates body ' s physiological rhythm.In recent years, Global Natural Disasters frequency is many, and the production directly having influence on paddy rice seriously occurs for shortage of water resources, rice blast, and arid and rice blast have become the one of the main reasons of Rice Yield Loss Caused.Cultivate can drought resisting blast resisting, again there is naked body, Huang Ye, the CMS line of giant embryo proterties and hybrid rice, have important practical significance.The gene pyramiding of multiple paddy rice anti contravariance, useful specialized character is in maintainer material to Characters of Giant Embryo Rice three by the hybridization polymerization that backcrosses by the inventive method, to be hybridized with corresponding Characters of Giant Embryo Rice male sterile line by it again and backcross, being bred as high resistance naked body yellow leaf Characters of Giant Embryo Rice CMS line, is that giant embryo hybrid rice can improve resistance level, improve hybrid purity, is easy to mechanized harvest and improves the yield level that three are giant embryo hybrid rice with its preparation three.
Summary of the invention
The object of the present invention is to provide the selection of a kind of high resistance naked body yellow leaf Characters of Giant Embryo Rice CMS line, backcross polymerization by anti-for drought resisting, rice blast, naked body, these 4 kinds of gene pyramidings of yellow leaf in large embryo rice CMS line by hybridization, is bred as the Characters of Giant Embryo Rice CMS line with naked body, Huang Ye, drought-resistant, blast resisting characteristic.
For reaching above object, the present invention by the following technical solutions:
A selection for high resistance naked body yellow leaf Characters of Giant Embryo Rice CMS line, comprises the following steps:
1) select yellow leaf marker parent A, drought-resistant variety B, naked body rice parent C, blast resisting parent D be resistant parent, Characters of Giant Embryo Rice three is maintenance is recurrent parent E, makes hybridization A/B and C/D, must hybridize F

7) the yellow leaf Characters of Giant Embryo Rice maintainer of high resistance naked body and giant-embryo CMS lines are hybridized and 3 generations that backcrossed, and are namely bred as high resistance naked body yellow leaf Characters of Giant Embryo Rice CMS line.
Recurrent parent E is 1813geB, TgeB or 98-14geB, and its corresponding giant-embryo CMS lines is 1813geA, TgeA or 98-14geA.
More than 2 times of giant embryo the Characters to be embryo size be common rice embryo size.
Yellow leaf marker parent A is topaz B, and drought resisting parent B is green non-irrigated No. 1, and naked body rice parent C is light fragrant B, blast resisting parent D is Wunong 1.
The high resistance naked body be bred as yellow leaf Characters of Giant Embryo Rice CMS line has the characteristic of giant embryo proterties, naked body proterties, yellow leaf proterties, drought-resistant, blast resisting simultaneously.
beneficial effect of the present invention:
Effect of the present invention is respectively yellow leaf marker, drought resisting, naked body, blast resisting proterties to be aggregated in large embryo rice CMS line, be bred as high resistance naked body yellow leaf Characters of Giant Embryo Rice CMS line, preparing three with its is the resistance level that giant embryo hybrid rice can improve drought resisting, blast resisting, yellow leaf marker is easy to remove hybrid strain, improve hybrid purity, naked body proterties is easy to mechanized harvest and improves the yield level that three are giant embryo hybrid rice.With three of high resistance naked body yellow leaf Characters of Giant Embryo Rice CMS line preparation, to be giant embryo hybrid rice every mu prepare than former Characters of Giant Embryo Rice CMS line three is giant embryo hybrid rice check variety increase yield 15-20%.
