Abstract
The invention discloses a breeding method of a bare giant embryo red glutinous rice variety, belonging to the technical field of special rice breeding. The breeding method is characterized in that bare rice, giant embryo rice, red rice and glutinous rice varieties are taken as parents, genes, which respectively control the properties of bare body, giant embryo, red seed coat and glutinousness, are polymerized together by a technical method of paired hybridization and then hybridization, and then target characters, agriculture and yield characters are selected for multiple generations to breed the special rice variety with the properties of bare body, giant embryo, red seed coat and glutinousness. According to the breeding method, the genes, which respectively control the properties of bare body, giant embryo, red seed coat and glutinousness, are polymerized together, and the target characters, the agriculture and the yield characters are selected for multiple generations to breed the bare giant embryo red glutinous rice variety with the advantages of bare rice, giant embryo rice, red rice and glutinous rice. The bare giant embryo red glutinous rice variety is more insect-resistant, is more easy to be mechanically harvested, has rich nutrients and functional components, and has a better health care function. The breeding method provided by the invention is simple, and is high in breeding efficiency and good in benefit.
Description
Technical field
The present invention is specifically related to the selection of the red glutinous rice variety of a kind of naked body giant embryo, belongs to Special rice breeding technical field.
Background technology
" naked body rice " is exactly that whole body is without the paddy rice of hair, because sick worm is difficult for adhering to and invading, performance has stronger resistant to diseases and insects, when manual harvesting and threshing, can reduce that skin is itched and the damage to skin, be easy to mechanized harvest, add free from dust in man-hour, can reduce environmental pollution, so claim again " environmental protection paddy rice ".Characters of Giant Embryo Rice contains natural nutrition element and the physiological activators such as abundant γ-aminobutyric acid, mineral matter, amino acid, vitamin.It is the abundantest that red rice is rich in numerous nutrients, particularly irony, has the effect of enriching blood and preventing anaemia, also contains abundant phosphorus, and vitamin A, B group can improve malnutritive, the effective symptoms such as fatigue, lassitude and insomnia of releiving.The materials such as the contained pantothenic acid of red rice, vitamin E, have the effect that suppresses carcinogen, especially obvious especially to the effect of prevent colon cancer.Glutinous rice is nice and can be processed into numerous food product, by numerous people are liked.There is at present the report that is bred as various special rices both at home and abroad, but above 4 kinds of proterties are combined in a rice varieties and have no report.If above 4 kinds of proterties can be gathered in a kind, not only can greatly improve various nutrient components and the functional component of its rice, and can Resistant and be easy to mechanized harvest.
summary of the invention
The object of the present invention is to provide the selection of the red glutinous rice variety of a kind of naked body giant embryo, utilize genetics principle, by the technical method being hybridized after biparental cross, to control respectively naked body, giant embryo, Red Indian race skin with together with waxy gene pyramiding, and through the too much selection of generation to objective trait, agronomy and yield traits, be bred as and there is naked body, giant embryo, Red Indian race skin and waxy proterties simultaneously, be rich in various nutrient components, there is the rice variety of good health care.
For reaching above object, the present invention by the following technical solutions:
1) take naked body rice as parent 1, take Characters of Giant Embryo Rice as parent 2, take red rice rice as parent 3, take glutinous rice as parent 4, do to hybridize respectively " parent 1/ parent 2 " and " parent 3/ parent 4 ";
2) plant respectively hybrid combination " parent 1/ parent's 2 " hybridization F
1for F
1-A and " parent 3/ parent's 4 " hybridization F
1for F
1-B, makes to hybridize " F flowering stage
1-A/F
1-B ";
3) plantation hybrid combination F
1-A/F
1the hybrid F of-B
1generation, the mixed hybrid F that receives of maturing stage
1for plant, bear seeds;
4) plantation 3) gained hybrid F
2generation, in the early tillering stage, by strain, carry out the screening of blade naked body proterties, remove the rice strain that blade shows non-naked body proterties, retain the rice strain of blade performance naked body proterties, the mixed hybrid F that receives of maturing stage
2for F that plant bears seeds
3;
5) the mixed F receiving
3seed, goes out after dry roughly, and brown rice is carried out to artificial screening, selects to have the brown rice grain of giant embryo and Red Indian race skin proterties simultaneously, and the selected brown rice grain with giant embryo and Red Indian race skin proterties carries out waxy check by grain, selects wherein to have waxy brown rice grain simultaneously;
6) plantation 5) screening gained brown rice grain, adopt sterile working method, in the test tube that is added with MS medium, germinate, after seedling, transplant in land for growing field crops, maturing stage selects the individual plant that economical character is excellent, ripening rate is high and yield traits is good to reserve seed for planting respectively, after dry, go out roughly, retain and all there is the F that Red Indian race skin proterties and the unseparated individual plant of color obtain
4seed;
7) strain plantation 6) screening gained F
4seed, select the individual plant listing mark that loose powder proterties is good flowering stage, maturing stage selects the individual plant that economical character is excellent, ripening rate is high and yield traits is good to reserve seed for planting respectively in listing mark strain, goes out after dry roughly, retains and all has the F that Red Indian race skin proterties and the unseparated individual plant of color obtain
5seed;
8) strain plantation 7) screening gained F
5seed, the maturing stage is selected the individual plant that economical character is excellent, ripening rate is high and yield traits is good, can shape and be bred as the red glutinous rice variety of naked body giant embryo.
The red glutinous rice variety of naked body giant embryo being bred as has naked body, giant embryo, Red Indian race skin and waxy proterties simultaneously, and in producing plantation in many generations, performance is stable, not separated.
In step 4), plant 3) gained hybrid F
2in generation, 2000-3000 strain is selected by its colony.
The naked body rice that the present invention adopts can be light 158, light 159, and Characters of Giant Embryo Rice can be MhgeR, TgeB, and red rice rice can be Nan Hongbao, Gui Hongzhan, and glutinous rice variety can be good glutinous extensive No. 1, good glutinous extensive No. 2, good glutinous extensive No. 3.
Beneficial effect of the present invention:
Effect of the present invention is controlling respectively naked body, giant embryo, Red Indian race skin with together with waxy gene pyramiding, and through the too much selection of generation to objective trait, agronomy and yield traits, be bred as and there is naked body, giant embryo, Red Indian race skin and waxy proterties simultaneously, it has advantages of that naked body rice, Characters of Giant Embryo Rice, red rice rice and glutinous rice have simultaneously, compared with Resistant be easy to mechanized harvest, be rich in various nutrient components and functional components, there is good health care.Breeding method of the present invention is simple, breeding efficiency is high, profitable.
