Abstract
The invention belongs to the field of heterosis application and in particular relates to a method for producing rice hybrid Guangliangyou 206. According to the invention, a new combination of three-line early rice is produced by hybridizing three-line male sterile line Guang 8S with restorer line D208, wherein the female parent Guang 8S is quoted from high-yield, high-quality and high-resistance three-line male sterile line selected and bred by teacher Yang Zhenyu; male parent restorer line D208 is introduced. The hybrid has the characteristics of high and stable yield, strong disease resistance and high biological yield.
Description
Technical field
The present invention relates in the production method of hybrid rice seed wide two excellent 206, is to utilize three line method to produce the method for the new combination of hybrid rice.
Background technology
China is paddy rice big country, and rice breeding technology maintains the leading position in the world always.But because the growth of Chinese population, the food problem that reply increases population remains the problem that China's agricultural needs most solution.Though it is hybrid rice seed production that the cost of three lines paddy seed is higher than two, because two be the production of hybrid seeds, have a big risk, be subjected to the uncontrollability of weather effect.Plant industry company in order to reduce the risk of production, produce hybrid rice seed, be still the maximum method of present kind industry company's employing with three line method.The shortening of the alternative time limit of kind at present reaches in order to enlarge with planting the needs that industry company competes abroad, and the three lines paddy crossbreed of seed selection safety is a most important task in present China rice breeding circle.
Summary of the invention:
The objective of the invention is to utilize the hybrid vigour theory, select high-combining ability, economical character is good, genotype is isozygotied, parents' affiliation is far away hybridization between selfed lines for use, produce high yield, disease-resistant hybrid rice seed.
The invention provides the production method of hybrid rice seed wide two excellent 206, comprise the use inbred line, safety is isolated, and regulates date of seeding, suitable row ratio, and roguing, results utilize three to be that wide 8S of male sterile line and recovery are that D208 produces hybrid rice kind wide two excellent 206 in good time.
Wherein said three is that the wide 8S of male sterile line is to be male sterile line by the high yield of Yang Zhenyu teacher seed selection, high-quality, high anti-three.
Wherein said recovery is D208, draws the paddy rice research institute from Agricultural University Of Nanjing, has applied for Ministry of Agriculture's new variety of plant protection at present.
The wide 8S of the biomaterial that the present invention relates to, D208 are all open in non-patent literature.
Wide 8S is open in total (the 58th phase) kind power application on March 1st, 2009 bulletin.
D208 is open in 1 day the 4th phase of July in 2006 Ministry of Agriculture's new variety of plant protection bulletin.
Advantage of the present invention and good effect are:
This combination output height, plant type is loose moderate,, sword-like leave is straight and upright, and cane is sturdy, and tillering ability is strong, big panicle many grains per panicle, it is close grain, the ripening rate height,, breeding time is short, and ripe phase annesl is good.Resistance is better, and rice is of fine quality, 122.0 centimetres of plant heights, and mu is fringe 16.5 ten thousand effectively, several 190.8 of every total grain panicle, ripening rate 84.5%, thousand kernel weight 29.2 grams.
Embodiment
Following examples are used to illustrate the present invention, but are not used for limiting the scope of the invention.
Embodiment 1: the concrete production process of crossbreed of the present invention wide two excellent 206
Wide two excellent 206 is to be that wide 8S of male sterile line and recovery are that D208 hybridization produces by three.
Wide 8S is that the wide 8S of male sterile line is to be male sterile line by the high yield of Yang Zhenyu teacher seed selection, high-quality, high anti-three.
Recovery is D208, and wherein said recovery is D208, draws the paddy rice research institute from Agricultural University Of Nanjing.
Embodiment 2: the production technology of crossbreed of the present invention wide two excellent 206
(1) safety is isolated: space length＞500 meter, or other rice varieties of heading flowering period of being separated by more than 15 days carries out the production of hybrid seeds and isolates.
(2) begin sowing in good time: first phase male parent is than maternal Zao inserting 25～30 days, or leaf order difference 6.5-7.5 leaf, or the effective accumulated temperature father and mother originally differ from, and (area is maternal in the Soviet Union sows 20-25 day in May about 205 ℃, sowing about the April 24 male parent first phase), the second phase, the third phase are separated by about 7 days with preceding first phase respectively, or are separated by 12 days with two phase male parents.
(3) rational close planting, suitable row ratio: 16.7 * 10 centimetres of seeding row spacing female parents, plant foot 15～180,000 basic seedlings for every mu, the male parent spacing in the rows is 16.7 centimetres, and the aisle was 33.3 centimetres when duplicate rows was planted, and father and mother's one's own profession ratio is 2: 20 or 1: 12.Row is to vertical with locality predominant wind at heading stage.
(4) use " 920 " technology and artificial supplementary pollination; Spray 920 during 10% female parent heading, every a spray 20 grams, the 4th spray 5 grams.Catch up with pollen to carry out artificial supplementary pollination whole flowering stage every day at florescence from fringe phase beginning to neat fringe.
(5) prevent and treat the kernel smut technology: black spirit (producer's medicine) prevents and treats kernel smut 2-3 time continuously at cut phase, fringe phase beginning and full heading time with going out.
(6) roguing technology: whole growing is pulled out the high temperature sensitive variant of removing the loose powder phenomenon among this outside proterties such as variant of form, fertility and father and mother and the maternal wide 8S, contains spend back about 23 days timely results hybrid seed.
Embodiment 3: the cultivation application technology of wide two excellent 206 crossbreed
1, begins sowing in good time, cultivate strong seedling.Semilate rice sowing, 18～22 days length of time rice seedlings grow are done in Hubei.
2, rational close planting.13 centimetres of transplanting specification 23 (or 26) cm x, 2 paddy seedlings of every root and stem of certain plants or mu are thrown 1.8～2.2 ten thousand root and stem of certain plants.
3, rich water quality management: N, P, the fertile compounding application of K use sufficient base manure, early execute fetilizer for tillering, and the later stage is seen the seedling fertilising; Shallow water is turned green, thin moisture tiller, and enough seedling dry fields, fringe phase water conservation, the later stage alternation of wetting and drying is avoided and is cut off the water supply too early to ripe.
4, prevention and elimination of disease and pests in time.
