Abstract
The present invention relates to a method for producing the seeds of hybrid rice by using seed color marker characters. In the method, the seed color marker characters are transferred into the existing sterile lines or restoring lines and bred so that the marker character sterile lines or the restoring lines with different mature periods are bred; the marker character sterile lines and no marker character restoring lines, which have close sowing and earing periods, are mixed according to the ratio of 5 to 1 and sowed, or no marker character sterile lines and marker character restoring lines, which have close sowing and earing periods, are mixed according to the ratio of 6 to 1 and sowed; based on the color of the harvested seeds, the seeds with marker characters and the seeds without the marker characters are separately selected by a photoelectric separator so that the seeds of hybrid rice are obtained. The seed production method of the present invention has the characteristics of simple and easy operation, stable yield and high yield.
Description
The invention belongs to the rice heterosis utilization technical field, be specifically related to a kind of golden shell male sterile line or recover the seed selection of system and the production method of crossbreed thereof.
Hybrid rice can produce utilization on a large scale in China, mainly is by labor-intensive hybrid rice seed production technology.But there are a lot of problems in this technology, can't adapt to the mechanization production of hybrid seeds, along with The development in society and economy, rural laborer's transfer, the process of seed engineering industrialization is accelerated, and realizes that the mechanization seeding technique is to reduce production costs and the inexorable trend of seed engineering industrialization.
The concrete technological deficiency of existing hybrid rice seed production is that male-sterile seed and recovery are that seed color is careless look (faint yellow), and the two can't be distinguished.Therefore, when producing, can't realize in seed mechanization mixed seeding, the mixed receipts; Crossbreed and parent's (recovering system) can't be separated.
The purpose of this invention is to provide one can make hybrid rice seed production simple and easy to do; And can use existing agricultural tool to sow, gather in the crops and effectively hybrid rice seed and parent's (recovering system) are separated, produce the commercialization hybrid seed that meets country's kind substandard.
Content of the present invention is achieved in that
A kind of method of utilizing the seed color mark property to produce hybrid rice seed among existing male sterile line or recovery system, is bred the transformation of seed color mark property the seed color mark property male sterile line of different maturation period or is recovered system; With broadcast close seed color mark property male sterile line of the phase of taking out and unmarked proterties recover system or unmarked proterties male sterile line and the recovery of seed color mark property be seed in 5: 1-6: 1 ratio mixed seeding, the seed of results, electronic colour separator with the polished rice processing machine carries out sorting according to seed color, and the seed that will have mark property does not obtain hybrid rice seed with there being the seed separation of mark property.
The seed color mark property is golden shell.
The seed color mark property is sterile to be golden GA.
It is gold 422 that the seed color mark property recovers.
The seed mixed seeding is live with planting with sowing machine or artificial field.
The seed results are for mixing harvesting with harvesting facility field or adopting and manually gather in separately by seed color in the field.
Seed separation obtains to meet the hybrid rice seed of country's kind substandard for the seed that will mix receive in the seed farm carries out sorting with the electronic colour separator of polished rice processing machine.
Below further narration content of the present invention:
The present invention mainly comprises golden shell male sterile line or recovers the seed selection and the hybrid rice production of hybrid seeds two aspects of system.
1, the seed selection of golden shell male sterile line or recovery system: paddy rice husk color generally is divided into careless look (faint yellow), golden (buff), purple, black.And existing production gone up used male sterile line, recovery system and F
1Seed is careless look.Therefore with among existing male sterile line of golden shell character gene input or the recovery system, breed the golden shell male sterile line of different maturation period or recover system.Male sterile line gold GA, the recovery of golden shell of now having bred golden shell are gold 422 etc.
2, seeding technique: will broadcasting close golden shell male sterile line of the phase of taking out and careless look shell, to recover that system or careless look shell male sterile line recover with golden shell be to prepare, concrete measure is as follows: 1. the sowing: male sterile line and recovery be seed in 5: 1-6: 1 ratio is carried out mixed seeding, both can adopt planting with sowing machine, also manually the field is live; 2. gather in the crops: can use harvesting facility field to mix harvesting, also can adopt manually and gather in separately by seed color in the field; 3. sorting: adopt the electronic colour separator of existing polished rice processing machine that the seed that seed farm mixes results is carried out sorting, because of the electronic colour separator (ESM) of polished rice processing machine is to be the sorting standard with the seed color, be easy to golden shell seed and careless look shell seed are separated, the present patent application people's result of the test is a sorting index 99%, is higher than country and plants substandard.
Advantage of the present invention and good effect are as follows:
1, simple: the present invention can adopt existing farm machinery to realize field machinery sowing, results, the labor savings of seeding technique, reduce production costs.
2, high and stable yields: at first be because the present invention adopts the parent's production of hybrid seeds with the ripe phase, needn't carry out the florescence and regulate, thereby reduce the probability that causes the flowering asynchronism underproduction because of factors such as weathers widely; It two is even because of recovering to tie up in the seed farm random distribution, and pollen scatters rationally, is easy to obtain high yield.
Narrate specific implementation method of the present invention below:
1, golden shell character gene is changed over to the male sterile line of different maturation period or recover in the system, obtains stable, available golden shell male sterile line or recovers be.This gold shell is sterile to be golden GA, and it is gold 422 that this gold shell recovers.
2, golden shell male sterile line and careless look shell are recovered system or careless look shell male sterile line and golden shell recovery system in 5: 1-6: 1 ratio is carried out mixed seeding, can adopt planting with sowing machine, and also manually the field is live.Results: can use harvesting facility field to mix harvesting, also can adopt manually and gather in separately by seed color in the field.Other field management measure (as apply fertilizer, water, insect protected, diseases prevention etc.) with field rice produce identical.
3, will mix and receive seed and carry out sorting, and obtain hybrid rice seeds with the electronic colour separator of polished rice processing machine.
Claims (1)
1, a kind of method of utilizing the seed color mark property to produce hybrid rice seed is characterized in that: the transformation of golden shell character gene among male sterile line or recovery system, is bred band seed color mark property male sterile line gold GA and recovery system gold 422; With broadcast the phase of taking out close seed color mark property male sterile line gold GA and unmarked proterties recover system or unmarked proterties male sterile line and the recovery of seed color mark property be golden 422 seeds in 5: 1-6: 1 ratio mixed seeding, the results seed, electronic colour separator with the polished rice processing machine carries out sorting according to seed color, and the seed that will have mark property does not obtain hybrid rice seed with there being the seed separation of mark property.
