Abstract
The invention relates to a high-production low-danger propagation technology of a photo thermo sensitive genic male sterile rice, in which the propagation cost and the danger of the photo thermo sensitive genic male sterile rice are lowered by utilization of the natural low-temperature condition at high altitudes, the difficulties in propagating the dual-purpose genic male sterile rice are avoided and the development of a two-line hybrid rice is promoted. The method comprises the following steps: selecting a propagation base at appropriate altitudes that the latitude is 24 degree to 26 degree and the altitude is 1500 m to 1650 m; arranging a sowing season that the heading and flowering stage can be on about August 10th and the seeding time is generally on April 1st to April 16th at the altitudes of 1500 m to 1650 m; implementing the cultivation management technology that transplant is carried out when the sterile line leaf age is 4-5 leaves, compact planting is conducted moderately, the planting space is generally 15cm*20cm or 13cm*15cm for single-plant interposition; and arranging temperature reduction facilities in abnormal temperature in areas with favorable irrigation conditions, so that the temperature can be lowered by cold water in a mountain spring once the external temperature becomes abnormal and can not meet the temperature requirement of the sterile line in the sensitive stage.
Description
Technical field:
The present invention relates to the low-risk high yield propagation technique of the high height above sea level of photo-thermo sensitive male nuclear sterile rice line.The proposition of this programme is to utilize high altitude localities natural low temperature condition, has reduced the reproductive-cost and the risk of photo-thermo sensitive male nuclear sterile rice line, with the development that promotes double-linear hybrid rice to a certain extent.
Background technology:
Combo freedom, numerous kind are simple and easy, to recover spectrum extremely wide and do not have superiority such as sterile cell's matter negative effect because of showing for double-linear hybrid rice, receive numerous experts of rice breeding circle and scholar's great attention.Double-hybrid rice strains is compared with three line method has huge high yield potentiality, sees from the dual purpose genic male sterile line that selects at present, cultivate a kind of can the safe production of hybrid seeds, again can numerous kind successful photo-thermo-sensitive genic male sterile line be only the basic outlet of two-line hybrid rice.The present photo-thermo-sensitive genic male sterile line sterility origin temp that selects of China is generally at 23 ℃～24 ℃; Such dual purpose genic male sterile line; Even when carrying out hybrid seeding in full summer, still possibly fertility fluctuateed because of receiving the influence of abnormal low temperature; Cause hybridization seed production purity to descend, or even production of hybrid seeds failure.Therefore, the effective ways of raising two line method production of hybrid seeds safety are the photo-thermo-sensitive genic male sterile lines of cultivating critical temperature of sterility low (21 ℃～23 ℃).Yet receive the restriction of the critical low temperature of physiology, the educated temperature range of the dual purpose genic male sterile line fertility-sensitive period of this low critical temperature of sterility very narrow (19 ℃～21 ℃) just makes under the natural conditions on the spot numerous kind of very difficulty.Yet the numerous utilization with the cold water string irrigating propagation method of Hainan spring, the interim numerous kind of problem of soluble dual purpose genic male sterile line to a certain extent will cause (the numerous kind of success rate in Hainan are less than 40%) such as numerous kind of failures but increased numerous kind of cost and careless slightly.Therefore, the safety in production problem of numerous kind of dual purpose genic male sterile line and two-line hybrid rice seed becomes the main bottleneck of restriction double-hybrid rice strains development.Given this, the research of carrying out numerous kind of problem of dual purpose genic male sterile line has very important meaning.
Summary of the invention:
The objective of the invention is in order to overcome numerous kind of difficulty of paddy rice dual-purpose caryon sterile line.According to the requirement of the dual purpose genic male sterile line fertility-sensitive period of different critical temperature of sterility and heading flowering period to temperature; Utilize the special three-dimensional weather conditions in Yunnan Province and combine analysis more than 20 year meteorological data of each meteorological site of this province; Can know in some low latitudes high altitude localitiess such as the Baoshan, Yunnan Province, Yuxi; The paddy rice dual-purpose caryon sterile line that the breeding critical temperature of sterility is 21 ℃～23 ℃, the probability of its reproductive success can reach about 95%.Be a kind of stable and high yields and breeding technique efficiently, can increase numerous kind output and benefit, can improve the purity of seed again.
Paddy rice dual-purpose caryon sterile line breeding technique provided by the invention comprises: the cooling installation the when selection in suitable numerous kind of base of height above sea level, the arrangement of sowing season, cultivation management technology and thermic anomaly.
Wherein said numerous kind of base; Requirement is some low latitudes high altitude localitiess (24 °～26 ° in latitudes; Height above sea level 1500m～1650m scope); The isolation condition: its peripheral 500m can not plant other paddy rice with interior, and perhaps fringe phase beginning of fringe phase beginning of other paddy rice and breeding male sterile lines differed more than 30 days in the multiplication plot.Require illumination and temperature can satisfy the area of conventional rice normal growth, growth simultaneously.
Arrange wherein said sowing season; Length breeding time according to male sterile line is arranged sowing time; Arranging suitable fertility-sensitive period is the key of paddy rice dual-purpose caryon sterile line reproductive success; Require heading flowering period should be about August 10 could safety, generally be arranged in 1～April 16 April its sowing time in the area of height above sea level 1500m～1650m scope.
Wherein said cultivation management technology is transplanted when requiring male sterile line leaf age 4～5 leaves, and the seeding row spacing of 15cm * 20cm or 13cm * 15cm is adopted in appropriate dense planting usually, single this transplanting.Its rich water quality management is undertaken by usual manner, the omnidistance attention extermination of disease and insect pest.
Cooling installation during wherein said thermic anomaly; Promptly breed the base and can be chosen in area with good irrigation conditions; In case male sterile line fertility-sensitive period temperature requirement takes place can not satisfy unusually in outside air temperature; Can reduce temperature through mountain spring cold water; Thereby guarantee the low temperature requirement of male sterile line fertility-sensitive period, improve the safety coefficient (, can know that the temperature during the July～August of some low latitudes high altitude localitiess such as Yunnan Province's Golconda, Yuxi does not almost have above 23 ℃) of breeding through analysis to more than 20 year meteorological data of each meteorological site of this province.
Embodiment:
