Abstract
The invention discloses a breeding method for a long grain type high temperature resistance conventional japonica rice variety. The breeding method for the long grain type high temperature resistance conventional japonica rice variety comprises the specific steps that 1, zhendao 99 is adopted as a female parent and hybridized with a high temperature resistance japonica rice material 09-22, and a high temperature resistance variety G-125 is bred through three years and six generations; 2, the long grain type japonica rice variety jiahe 212 is adopted as a female parent and hybridized with the high temperature resistance variety G-125, and 82 long grain type japonica rice strains are bred through three years and six generations; 3, the 82 strains are sown at different stages, and seven strains with the fruiting rate being 90% are selected on the condition of lasting high-temperature weather condition in the rice flowering stage; 4, the seven strains are subjected to a yield comparison experiment, and one strain with 5% higher yield control variety is reserved. According to the breeding method for the long grain type high temperature resistance conventional japonica rice variety, the bred japonica rice variety is bred, the yield is high, the high temperature resistance is good, and the rice can be sown ahead of time when it is hotter, and the planting time is ahead of the schedule.
Description
Technical field
The present invention relates to Oryza sativa L. breeding technique field, particularly relate to the selection of a kind of long grain type high temperature resistant conventional japonica rice kind.
Background technology
Oryza sativa L., is annual gramineae plant, high about 1.2 meters, leaf length and flat, panicle is made up of many small ears.Institute's i.e. Oryza glutinosa of knot reality, claims rice or rice after shelling.Nearly half population in the world, Oryza sativa L. can be divided into long-grained nonglutinous rice and japonica rice, early rice and middle late rice, Oryza sativa L. var. glutinosa Matsum. and non-Oryza sativa L. var. glutinosa Matsum..The tied grain of rice of Oryza sativa L. claims rice or rice after shelling.Oryza sativa L. is in addition to edible, it is also possible to making wine, refine sugar and make the raw material of industry, rice husk, rice straw also have a lot of use.Oryza sativa L. belongs to grass family Oryza, is a crop the most ancient.According to archaeological discovery, Oryza sativa L. is in the plantation history at least about 7000 of China.
Current domestic long grain type japonica rice variety mostly is late japonica rice, non-refractory, needs late sowing to avoid hot weather, it is impossible to early sowing.The present invention japonica rice variety that the heat-resisting ability of long grain type japonica rice variety Yu self-fertile is strong hybridizes, and selects the long high temperature resistant japonica rice variety of grain type.
Summary of the invention
The invention aims to solve shortcoming present in prior art, and the selection of a kind of long grain type high temperature resistant conventional japonica rice kind proposed.
To achieve these goals, present invention employs following technical scheme:
The selection of a kind of long grain type high temperature resistant conventional japonica rice kind, the selection of this long grain type high temperature resistant conventional japonica rice kind specifically comprises the following steps that
S1: it is maternal for using town rice 99, hybridizes with high temperature resistant japonica rice material 09-22, selected high temperature resistant kind G-125 through 3 years 6 generations；
S2: be maternal with long grain type japonica rice variety Jiahe 212, hybridizes with high temperature resistant kind G-125, selected long grain type japonica rice strain 82 through 3 years 6 generations；
S3: 82 strain interval sowings, select the strain 7 of setting percentage 90% under rice anthesis continuous high temperature weather conditions；
S4: 7 strains are done Yield compari@test, retains the strain 1 of yield increased kind high 5%.
Preferably, the rice growing place in described step S3 is Luzhou, Sichuan city.
Preferably, in described step S3, altithermal hot conditions is temperature 39 degrees centigrade.
The selection of a kind of long grain type high temperature resistant conventional japonica rice kind that the present invention provides, the japonica rice variety of selection-breeding, yield is high, and resistance to elevated temperatures is good, can shift to an earlier date and sow at higher temperature weather, implantation time in advance.
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with specific embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Embodiment 1
The selection of a kind of long grain type high temperature resistant conventional japonica rice kind, the selection of this long grain type high temperature resistant conventional japonica rice kind specifically comprises the following steps that
S1: it is maternal for using town rice 99, hybridizes with high temperature resistant japonica rice material 09-22, selected high temperature resistant kind G-125 through 3 years 6 generations；
S2: be maternal with long grain type japonica rice variety Jiahe 212, hybridizes with high temperature resistant kind G-125, selected long grain type japonica rice strain 82 through 3 years 6 generations；
S3: 82 strain interval sowings, select the strain 7 of setting percentage 90% under rice anthesis continuous high temperature weather conditions；
S4: 7 strains are done Yield compari@test, retains the strain 1 of yield increased kind high 5%.
Rice growing place in described step S3 is Luzhou, Sichuan city.In described step S3, altithermal hot conditions is temperature 39 degrees centigrade.
The selection of a kind of long grain type high temperature resistant conventional japonica rice kind that the present invention provides, the japonica rice variety of selection-breeding, yield is high, and resistance to elevated temperatures is good, can shift to an earlier date and sow at higher temperature weather, implantation time in advance.
The above; it is only the present invention preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; any those familiar with the art is in the technical scope that the invention discloses; according to technical scheme and inventive concept equivalent or change in addition thereof, all should contain within protection scope of the present invention.
Claims (3)
1. the selection of one kind long grain type high temperature resistant conventional japonica rice kind, it is characterised in that: the selection of this long grain type high temperature resistant conventional japonica rice kind specifically comprises the following steps that
