Description
The invention belongs to the rice heterosis utilization technical field, be specifically related to a kind of method with perennial root method breeding male sterile lines, recovery system and production perennial root hybrid rice seed and hybrid rice.
The rice of the world today is all produced with annual rice.Planted annual rice approximately existing 10,000 years.Population heightens and the rice field minimizing now.The rice high yield breeding fluctuates over nearly 30 years.It is almost hopeless to desire to increase per unit area yield 20% again by prior art.If or else volume increase has the danger that grain shortage takes place again.
Existing annual rice technological deficiency is:
1, necessary every year of the annual rice of plantation or per season are ploughed rice field of rake; Must every year or per season buy and sow one time seed; China is based on transplanting rice, also must every year or per season seedling and plant.These measures must expend a large amount of manpower financial capacities.
2, not only cost is high but also lure that footy decades ago secondary disease insect pest nearly two more than ten years rise to serious sick worm rapidly into to carry out intensive culture for high yield, as the virus disease of brown plant-hopper and propagation thereof.The fungal disease that brings out for pest control and intensive culture is little pesticide grown again, serious environment pollution.
3, No. 5158879 patents of U.S.'s approval on October 27th, 1992: the perennial root male sterile line is produced hybrid rice seed, and inventor Li Qin repaiies.This patent is produced annual hybrid rice seed with the perennial root male sterile line, but these perennial root male sterile lines root-like stock proterties in the seed selection process disappears and can not transplant rejuvenation automatically.So the perennial root male sterile line must artificial be transplanted rejuvenation, otherwise can be degenerated to little grass and do not have value.Make the utilization of can not going into operation so far of this patent.In addition, inventor Li Qin repaiies and stops providing technical application to American side, makes American side have most Patent right this patent to scrap in the U.S..
The purpose of this invention is to provide and a kind ofly produce the method for hybrid rice, broadcast once and perennial root is constantly produced perennial perennial root hybrid rice seed for many years with the perennial root male sterile line with the perennial root method.This perennial root F
1The rice strain that grows after hybrid seed is broadcast can perennial root vegetative propagation fixed rendition hybrid vigour.
The present invention is achieved in that
A kind of method with perennial root method production hybrid rice comprises male sterile line, recovers system's selection, hybrid F
1Production with hybrid rice; It is maternal selecting perennial root sterile, and selecting perennial root to recover is male parent, and preparation perennial root crossbreed produces the perennial root hybrid rice with the perennial root crossbreed again.
The perennial root of selecting is sterile to be GP8A or male sterile line CP8A.
Select sterile be not sensitization perennial root male sterile line fully.
It is G4362 or the P1839 that measures from existing conventional variety that the perennial root of selecting recovers system; Also available existing recovery system and perennial root are that selection cross recovers system.
Hybrid F
1Be not sensitization perennial root F fully
1, this perennial root F
1Can vegetative propagation reappear hybrid vigour for many years; And the maturation of successively earing, gather in once every month, and annual the harvesting repeatedly is until just dormancy early winter.
Hybrid F with the production of perennial root method
1, mix the receipts back and sub-elect hybrid seed with mesh screen according to this grain of father and mother width difference.
Advantage of the present invention and good effect are as follows:
1, output height.Not sensitization perennial root hybrid rice does not have independent vegetative growth phase and forms rice yield with the light hot water conditions fully effectively fully, spike of rice of perennial root rice field harvesting in every month, and year receipts repeatedly make year mu gross output than now increasing by 20% at least with annual hybrid rice.Perennial root rice yellow maturity fringe is than the high 30-40cm of not earing, and is convenient to artificial or mechanical harvesting does not injure the new fringe of next group again.
2, the seed production cost is low.Perennial root male sterile line vegetative propagation purity height needn't impurity elimination.When not sensitization perennial root male sterile line and precocious perennial root recover to be assembly fully, repeatedly gather in the crops hybrid seed every year.The perennial root male sterile line has long stigma, thin fringe etc. to help the crucial proterties of different friendship, and outcrossing can reach 70%.In a word, the seed production cost is than now hanging down 40% with annual hybrid rice.
3, utilize perennial root F
1Cost is low.The perennial root hybrid rice is that rice stub is done kind to utilize again, and sowing was once received 5 years, the not dispenser Chinese caterpillar fungus of curing the disease.But some area Shaoshi or nitrogen fertilizer application not.No-tillage for a long time.In a word, can save a large sum of producing cost.
4, the annual tight topped permanent no-tillage hillside fields, nonirrigated farmland of green manure such as perennial root hybridization upland rice and perennial root clover can prevent erosion.
Specific embodiments of the invention are as follows:
Embodiment 1:
The present invention comprises that mainly perennial root male sterile line and recovery are seed selection, and the perennial root method is produced F
1Seed and perennial root utilize F
1Three aspects realized by following each step.
1, seed selection perennial root male sterile line and recovery system.The wild rice O.rufipogon in long medicine wild rice O.longistaminata and Liuzhou is the desirable wild parent of perennial root.Japonica rice G4362, P1839 etc. are high yield high-quality and perennial root donor.Breed perennial root caryon sterile line GP8A respectively and male sterile line CP8A is lost in the perennial root open country with them, two class male sterile lines all can sexual and vegetative propagation.It is G4362 that perennial root recovers, and P1839 directly measures from the japonica rice conventional variety, and also available existing recovery system and the hybridization of perennial root system bring out, and perennial root recovers system and carries out vegetative propagation and seminal propagation.
2, isozygoty the perennial root male sterile line with recover system hybridize perennial root F
1Vegetative propagation reappears hybrid vigour with for many years.
3, the perennial root hybrid rice is in permanent no-tillage paddy field or dry-land cultivation.Beneficial organism such as green manure, beneficial insect and beneficial microbe etc. and pest such as insect, weeds, disease etc. form natural equilibrium in the perennial root rice growth district, and pest is difficult for harm and causes disaster.So perennial root rice district is not dispenser insect pests grass basically.The main field operation of rice farming is exactly to gather in spike of rice.Stubble decomposition on the spot is fertile, and the diazotroph active region can not executed or Shaoshi nitrogenous fertilizer.Changed once new perennial root combination in about four to five years.
Perennial root male sterile line and the perennial root F that allots thereof
1Crossbreed all has underground root-like stock to transplant rejuvenation automatically, and perennial root does not wane for many years.Field density is regulated in the automatic transplanting of root-like stock voluntarily.And need not manually transplant rejuvenation and the artificial control field density of regulating.
Not sensitization perennial root male sterile line and not sensitization perennial root F fully fully thereof
1The perennial root strain be that successively heading is ripe, gather in once every month, the annual harvesting repeatedly.Until just dormancy early winter.
The perennial root male sterile line particularly can reach 100% high-purity by the male sterile line that the individual plant vegetative propagation forms.
Embodiment 2:
1, reestablish diplomatic relations seed selection perennial root male sterile line and recover system
The wild rice in light round-grained rice A/ Liuzhou // long medicine open country rice gets the perennial root open country F that tumbles
14020.From F
2And F
3Middle choosing obtains 4020-821 and the 4020-824-1 that root-like stock isozygotys.Caryon sterile line cultivated rice and 4020F
1The F of test cross
1Get the 886A that wild proterties has been eliminated with cultivated rice hybridization back selfing again.Hybridizing selfing again and brother and sister with 886A and 4020-821 hands over to isolate and meets the neat strong root-like stock of isozygotying of production needsing the not shattering perennial root caryon sterile line of drought resisting that resists cold.Educated strain in the caryon sterile line through selfing select wild abortion type perennial root maintenance line.Losing the male sterile line continuous backcross with the open country again breeds the perennial root open country and loses male sterile line.
It is that G4362, P1839 directly measure from the japonica rice conventional variety that perennial root recovers.Also available present recovery system and the hybridization of perennial root system bring out.Perennial root recovers system and carries out vegetative propagation and seminal propagation.
2, perennial root sterile line propagation and perennial root hybrid rice seed are produced
Perennial root mark caryon sterile line brother and sister friendship, self propagated, brother and sister are handed over or inbreeding population in hero can educate strain and eliminate fully and only stay sterile strain perennial root breeding and enlarge colony.The perennial root open country is lost male sterile line and is adopted backcross breeding and vegetative propagation expansion colony.
Perennial root male sterile line and perennial root recover system or the hybridization of annual recovery system.Because of root-like stock and cold-resistant perennial root all are dominance, so the perennial root male sterile line is the F that assembly goes out with recovering
1Must the tool perennial root.Be the F that annual recovery system allots
1Perennial root is variant between combination, can utilize according to qualifications.
It is that perennial root F is produced in alternate plantation that perennial root male sterile line and perennial root recover
1Hybrid seed.It is that automatic transplanting must make father and mother this staggered mixes growth that rhizomatic male sterile line or recovery are arranged.Can mix the receipts back and sub-elect hybrid seed with mesh screen according to this grain of father and mother width difference.Also can be at separative F
1The utilization of perennial root vegetative propagation is then selected by individual plant or group in the colony.
3, perennial root F
1The production utilization of hybrid rice
The field operation was identical with existing annual rice when the perennial root hybrid rice was set up primary group of hill body with grain sowing.Primary group of hill body, it is photostable fully making, and has after emerging independently then to enter reproductive stage vegetative growth phase and begin to break up young fringe.The perennial root strain that produces by rice stub of harvesting back for the first time then no longer include special nourish and grow but emerge and the fringe differentiation synchronously, ear during 4-5 sheet leaf after one month, after 30 days fringe yellow maturity.From emerging to the fringe yellow maturity about 60 days.When preceding a collection of perennial root seedling fringe was yellow, the 3rd batch of root turion of second batch of perennial root seedling booting emerged.Fringe differentiation, heading, the fringe yellow maturity three of Here it is perennial root rice are synchronous, carry out continuously.Constantly there is the fringe yellow maturity to receive the whole year in the torrid zone.In the subtropics, when monthly temperature was lower than 10 ℃, root-like stock stopped growing and changes dormancy over to, went up until temperature and sprouted the demutation new talent again after＞10 ℃.Though summer temperature is high, if the arid of chance, root-like stock also stops growing and dormancy.Meet rain after the drought, root-like stock is sprouted recovery life rapidly.The dormancy drought of going to a winter resort is that the wild rice of long medicine forms in more than one hundred million years evolve, and has entailed the perennial root hybrid rice now.So winter, the perennial root rice did not need man-made irrigation, inartificial winter protection protection.Perennial root hybrid rice of the present invention can be stood 5 ℃ of the coldest month sammings winter, extreme value-7.9 ℃.
It is comparatively extensive that the perennial root hybrid rice is compared with existing annual rice intensive culture.Under extensive relatively condition, repeatedly increase production by perennial root rice fixed rendition hybrid vigour and annual harvesting.
