Abstract
An optional combination method utilizing Xieqing Zao A to perform test cross on a plurality of male parents relates to the agricultural technology field. The optional combination method comprises the following methods of a first season: (1), introducing male parents with the best quality to achieve test cross with the Xieqing Zao A respectively, and arranging separation devices among cells to prevent pollen from being spread among the cells; (2), knowing about a period of duration and a head spreading period of each of the male parents in details, enabling the male parents and the Xieqing Zao A to achieve matching test cross according to phase difference; (3) observing the outcrossing maturing rate of each matching cell to reserving seeds with the outcrossing maturing rate higher than 85% and weed out seeds with the outcrossing maturing rate lower than 85%, observing other expression characters specified by seed production to weed out seeds with poor expression, independently harvesting, threshing and storing the seeds by the cells, and performing marks; a second season: separately planting seeds meeting the specifications of each cell in different cells, observing cultivated characters and biological characters of the seeds, observing and measuring the seeds subjected to plant diseases and insect pests, taking samples to perform rice quality appraisal, and reserving seeds meeting the standards in the cells to perform approval; a third season: fixing up test places, performing hybrid indica joint identification, and performing approval and promotion. The optional combination method is simple and practical, and the cultivated seeds are high in quality. Therefore, the optional combination method has high practical application significance and can increase grain yield.
Description
Technical field
The present invention relates to agricultural technology field, be specifically related to a kind ofly select combined method with a plurality of male parents of Xieqingzao A test cross.
Background technology
Xieqingzao A is that our province Guangde County institute of agricultural sciences breeds, the applicant bought should female parent kind power.A plurality of kinds such as up to now,, association excellent 63 with the combination of this female parent combo existing association is excellent 57, association is excellent 58, association is excellent 10, association excellent 78039, the male parent of a lot of high-qualitys is not also carried out effective combo.Present market preferably male parent and Xieqingzao A carry out the test cross combo and will breed better series of three-series hybrid rice and newly make up, its meaning is very big.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of method simple, and what be convenient to implement selects combined method with a plurality of male parents of Xieqingzao A test cross.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind ofly select combined method with a plurality of male parents of Xieqingzao A test cross, comprise the following methods step,
The first season:
1, introduce optimum male parent and Xieqingzao A test cross respectively, use spacer assembly between each residential quarter, guarantee mutually not go here and there between pollen powder;
2, understand in detail breeding time and the heading flowering period of each male parent, press poor phase combo test cross with Xieqingzao A respectively;
3, each combo residential quarter observation outcrossing seed-setting rate, outcrossing seed-setting rate reaches more than 85% and stays, and lower than eliminating, observes simultaneously other phene of production of hybrid seeds defined, and proterties is bad also eliminates, and each residential quarter is single receives, single threshing, list is stored, and performs mark;
The second season:
A district seed up to specification minute residential quarter is planted separately, observe cultivated character and biological character, arrange simultaneously the damage by disease and insect Observe and measure, sampling is carried out meter matter and is identified, standard compliant district seed is stayed submit to a higher level for approval or revision;
The third quarter:
Arrange the test site, participate in simultaneously assorted Xian and unite evaluation, authorization is promoted.
The invention has the beneficial effects as follows: the inventive method is simple, and the seed quality of cultivating is high, has very high practice meaning, increases grain yield.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with specific embodiment, further set forth the present invention.
Embodiment 1
A kind ofly select combined method with a plurality of male parents of Xieqingzao A test cross, comprise the following methods step,
The first season:
1, will be inside and outside the province top quality male parent introduce and Xieqingzao A test cross respectively, use spacer assembly between each residential quarter, guarantee mutually not go here and there between pollen powder;
2, understand in detail breeding time and the heading flowering period of each male parent, press poor phase combo test cross with Xieqingzao A respectively;
3, each combo residential quarter observation outcrossing seed-setting rate, outcrossing seed-setting rate reaches more than 85% and stays, and lower than eliminating, observes simultaneously other phene of production of hybrid seeds defined, and proterties is bad also eliminates, and each residential quarter is single receives, single threshing, list is stored, and performs mark;
The second season:
A district seed up to specification minute residential quarter is planted separately, observe cultivated character and biological character, arrange simultaneously the damage by disease and insect Observe and measure, sampling is carried out meter matter and is identified, the district seed that will meet province's comparison and review of bid standard stays submits to a higher level for approval or revision.
The third quarter:
Arrange the whole province's five experimental tests, participate in simultaneously the assorted Xian of the whole province and unite evaluation, authorization is promoted.
Above demonstration and described basic principle of the present invention and 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; that describes 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.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
