Abstract
The invention discloses a method for accelerating the rice breeding progress, and belongs to the technical field of plant breeding. The method includes the following steps that 1, F1-generation seeds are planted in an inland province in the first year, and F2-segregative-generation seeds are harvested; 2, about 2000 F2-segregative-generation seeds are planted in Hainan in the same year, and normal sowing, transplanting and field management are carried out; thirdly, two seeds at the tip of one main stem ear of each plant are picked in Hainan at the beginning of April in the next year after F2-segregative-generation seeds mature; fourthly, the 4000 picked seeds are mixed; fifthly, the mixed seeds are taken back to the inland province and subjected to germination accelerating, sowing, transplanting and field management; sixthly, rice planted in the fifth step is subjected to target single plant selecting and harvesting from the heading period to the maturing period. The method has the advantages that the rice breeding progress is accelerated, the F2-segregative-generation seeds can be planted in Hainan, and it can also be guaranteed that the characters of selected good single plants are not lost after the F2-segregative-generation seeds are taken back to the inland province.
Description
Technical field
The present invention relates to field of plant variety breeding technology, be specially a kind of method accelerating rice breeding process.
Background technology
Because of the reason of weather conditions, interior ground rice breeding is generally that a generation is planted in province interiorly, then arrive Hainan and plant a generation again, can plant for two generations in such 1 year, compared with planting with single province interiorly, the breeding time that generation can shorten half is added in Hainan, but be in F2 segregative generation at rice breeding, if be placed on Hainan plantation to carry out selection individual plant, Yin Hainanwen light resources and province, interior ground different, Hainan select have the individual plant of objective trait to get back to province, interior ground after, the Characters differs greatly, objective trait changes, excellent target proterties individual plant easily lost, if and do not carry out F2 segregative generation in Hainan, then delay again to postpone rice breeding process.
The present invention mainly solves problem described above.
Summary of the invention
The object of the present invention is to provide a kind of method accelerating rice breeding process, it both can plant F2 segregative generation in Hainan, and accelerate breeding process, the fine individual plant proterties selected after ensureing again to get back to province, interior ground is not lost.
Technical solution problem of the present invention adopts following technical scheme:
Accelerate a method for rice breeding process, it is characterized in that it comprises the steps:
(1) First Year, province plantation F1 generation seed, gathers in the crops to obtain F2 segregative generation seed interiorly;
(2) same year, about 2000 strains are planted F2 segregative generation seed in Hainan, normally sows, transplants and field management;
(3), at the beginning of 4 months Hainan next years, after F2 segregative generation seed maturity, 2 seeds of top tip part on a stem fringe are taked in every strain;
(4) above-mentioned 4000 seeds taked are mixed;
(5) seed of mixing is taken back province, interior ground and carry out vernalization, sowing, transplanting and field management;
(6) paddy rice that previous step is planted is carried out target Single-plant selection and harvesting in heading stage to the maturing stage.
Compared with prior art, its beneficial effect is in the present invention: accelerate rice breeding process, both can plant F2 segregative generation in Hainan, and the fine individual plant proterties selected after ensureing again to get back to province, interior ground is not lost.
Embodiment
Below the present invention is specifically described.
Accelerate a method for rice breeding process, it comprises the steps:
(1) First Year, province plantation F1 generation seed, gathers in the crops to obtain F2 segregative generation seed interiorly;
(2) same year, about 2000 strains are planted F2 segregative generation seed in Hainan, normally sows, transplants and field management;
(3), at the beginning of 4 months Hainan next years, after F2 segregative generation seed maturity, 2 seeds of top tip part on a stem fringe are taked in every strain;
(4) above-mentioned 4000 seeds taked are mixed;
(5) seed of mixing is taken back province, interior ground and carry out vernalization, sowing, transplanting and field management;
(6) paddy rice that previous step is planted is carried out target Single-plant selection and harvesting in heading stage to the maturing stage.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
