Abstract
The invention discloses a breeding method for a new variety of Scilly paddy. The breeding method comprises the following steps of: (1) arranging an original paddy nursery; (2) arranging a paddy breeding nursery; (3) arranging a paddy identifying nursery; (4) carrying out variety tests so as to obtain an excellent strain from the paddy identifying nursery. Paddy and the original paddy are comprehensively identified, compared and analytically researched from a larger area, so that the new variety with remarkably higher yield and remarkably better quality and the other economic characters compared with the existing popularized variety can be selected from the high-quality varieties selected from the paddy identifying nursery. After the method disclosed by the method is used, the new variety of the new Scilly paddy can be continuously bred, and the quality and the yield of the Scilly paddy can be improved.
Description
Technical field
The present invention relates to the sharp new rice variety selection of a kind of tin, belong to agricultural production.
Background technology
Xi Ligongmi is an oily non-glutinous rice in this locality of loyal town, Rongjiang County tin profit, the period of Ming and Qing, because of rice perfume (or spice), oil is high, delicious respects tribute as tribute rice to royal court, Xi Ligongmi is rich in the various trace elements of needed by human, belongs to rich selenium, zinc product, by the eater is liked.Do the special-purpose rice of high-quality in Qiandongnan Prefecture of Guizhou Province, 140 days breeding times, 97 centimetres of plant heights, 22.83 centimetres of spike lengths, several 98.6～181.8 of every total grain panicle, ripening rate 80%, thousand kernel weight 24.5 grams.This kind plant type compactness, well developed root system, tillering ability is strong, leaf look viridescent, rice is of fine quality, the food flavor mouthfeel is good, and in recent years, the sharp paddy rice of tin is adopted original kind always, degradation trend appears in the sharp paddy rice of tin.
Summary of the invention
The present invention aims to provide the sharp new rice variety selection of a kind of tin, guarantees to improve the yield and quality of the sharp paddy rice of tin.
The technical solution used in the present invention: the sharp new rice variety selection of a kind of tin comprises following operating procedure:
(1) original paddy rice garden is set
Original paddy rice is observed and preserves, and the evaluation value is selected good individual plant, as breeding material, every part of original single paddy rice is originally planted into a residential quarter, about 50-55 strains in every residential quarter, arrange in order the residential quarter, and 4-7 residential quarters that are separated by can arrange a check variety, as standard regions;
2. the paddy rice selective nursery is set
Separating rice is systematically observed all sidedly, identified and selects, therefrom select good and stable strain, in growing process, the performance of tackling each plant compares evaluation, show not enough neat and consistent and have the strain system of fine individual plant, can proceed individual plant and select; To the elite plant strain of performance neat and consistent, first this species test of sampling, all the other plant mix to be received, and prepare following generation to rise up into and identify the garden;
3. paddy rice is set identifies the garden
The material that derives from selective nursery, observe, identify the economic characters of each excellent strain and yield per unit area, stability and the uniformity of each excellent strain, the strain proterties of identifying the garden is better and stable, general 1 year of the test time limit in this garden, plantation residential quarter area is bigger, be generally 10～30 square metres, cultivation condition is near working condition, require to repeat 2～3 times, employing is arranged in proper order, every 4 residential quarters the check plot is set, according to the result of field and indoor evaluation, the good strain of performance is selected, for participation of following generation variety comparative test;
4. varietal yield test
From paddy rice identify the garden select excellent strain, than large tracts of land above good paddy rice being carried out comprehensive evaluation, comparison and analysis and research with the sharp original paddy rice of tin, therefrom select the kind that output, quality trait significantly are better than having now popularization.
Adopt said method, constantly the sharp new rice variety of tin that makes new advances of seed selection improves the quality and yield of tin profit paddy rice.
Embodiment
The sharp paddy rice of state-run breeding tin plantation, Rongjiang County.
(1) original paddy rice garden is set
Original paddy rice is observed and preserves, the evaluation value, select good individual plant, as breeding material, every part of original single paddy rice is originally planted into a residential quarter, about 50 strains in every residential quarter, arrange in order the residential quarter, 5 residential quarters that are separated by can arrange a check variety, as standard regions, provide foundation for selecting good parent;
2. the paddy rice selective nursery is set
Separating rice is systematically observed all sidedly, identified and selects, therefrom select good and stable strain, in growing process, the performance of tackling each plant compares evaluation, show not enough neat and consistent and have the strain system of fine individual plant, can proceed individual plant and select; To the elite plant strain of performance neat and consistent, first this species test of sampling, all the other plant mix to be received, and prepare following generation to rise up into and identify the garden;
3. paddy rice is set identifies the garden
The material that derives from selective nursery, observe, identify the economic characters of each excellent strain and yield per unit area, stability and the uniformity of each excellent strain, the strain proterties of identifying the garden is better and stable, general 1 year of the test time limit in this garden, plantation residential quarter area is bigger, be generally 30 square metres, cultivation condition is near working condition, require to repeat 3 times, employing is arranged in proper order, every 5 residential quarters the check plot is set, according to the result of field and indoor evaluation, the good strain of performance is selected, for participation of following generation variety comparative test;
4. varietal yield test
From paddy rice identify the garden select excellent strain, than large tracts of land above good paddy rice being carried out comprehensive evaluation, comparison and analysis and research with the sharp original paddy rice of tin, therefrom select the kind that output, quality or other economic characters significantly are better than having now popularization.
