Abstract
The invention provides a method for breeding indica rice restorer line with wide capability and bacterial leaf blight resistance, which comprises the following steps: constructing female parent, hybridizing indica rice restorer and japonica specie with wide capability, and obtaining a female parent; breeding by hybridization: hybridizing the female parent and an excellent restorer line, obtaining the indica rice restorer line with wide capability and bacterial leaf blight resistance. The indica rice restorer line with wide capability and bacterial leaf blight resistance Zhenhui98 bred by the method has the advantages of strong combining ability, disease resistance, wide capability and comprehensive agronomic characters.
Description
Technical field
The invention belongs to field of crop genetic breeding, particularly a kind of breeding method of Indica Rice restorer of extensively affine, bacterial blight-resisting.
Background technology
The incubation of China's indica Hybrid Rice and popularization, bring once leap to agricultural production, the growth of grain yield has been made to huge contribution, after particularly being bred as the eighties in last century bright extensive 63, with the combination of this restorer preparation once high with output, yield stability good, adapt to the good characteristic such as strong obtains large scale application in south China rice district, China's grain-production has been pushed to a new step, still had so far larger application area.Bright extensive 63 become the good Indica Rice restorer of applying up to now the area maximum.
After bright extensive 63 are bred as, although over more than 20 year, China various places breeding units also has been bred as many restorers, but the raising to hybrid rice yield potentiality, quality, resistance is very limited, rice breeding has entered a what is called of making slow progress " plateau (the Plateau) " stage.Therefore, take the efficient breeding approach, it is the key that realizes China's hybrid rice breeding new breakthrough that seed selection becomes good restorer to make strong excellent combination.
Summary of the invention
Goal of the invention: the breeding method that the purpose of this invention is to provide a kind of Indica Rice restorer of extensively affine, bacterial blight-resisting.
Technical scheme: the breeding method of the Indica Rice restorer of a kind of extensively affine, bacterial blight-resisting provided by the invention comprises the following steps:
(1) the maternal structure: with indica restorer line and the wide affine inter breed crossing of round-grained rice type, obtain maternal.
(2) crossbreeding: maternal and superior restorer line hybridization are cultivated to obtain to the wide Indica Rice restorer of affine, bacterial blight-resisting.
Preferably, described breeding method specifically comprises the following steps:
(1) the maternal structure: wide affine kind 02428 hybridization of indica restorer line bright extensive 86 and round-grained rice type obtains (bright extensive 86 * 02428) F
1;
(2) crossbreeding: with (bright extensive 86 * 02428) F
1for female parent, take Indica Rice restorer 084 as paternal hybrid, obtain the extensively Indica Rice restorer town extensive 98 of affine, bacterial blight-resisting.
The present invention also provides a kind of the utilization above-mentionedly to educate to such an extent that Indica Rice restorer hybridization obtains the breeding method of hybrid rice, and comprise the following steps: with Indica Rice, recovering is male parent, with sterile be maternal, be mixed with hybrid rice.
Wherein, the recovery of described rice indica hybrid parent round-grained rice is rice indica hybrid parent's round-grained rice restorer town extensive 98.
Wherein, described sterile be the safe A in Zhenshan 97a, Xieqingzao A, II-32A or Guangdong.
Beneficial effect: breeding method provided by the invention obtain extensively extensive 98 coordinate force in Indica Rice restorer town affine, bacterial blight-resisting are strong, disease resistance is strong, compatibility is wide, the comprehensive agronomy proterties is outstanding.
Particularly, the extensively Indica Rice restorer town extensive 98 affine, bacterial blight-resisting of acquisition has following outstanding advantage with respect to prior art:
1. coordinate force is strong.The genetic background and the wide affinity characteristic that there are the round-grained rice subspecies due to town extensive 98, with indica type three be after male sterile line Zhenshan 97a, Xieqingzao A, II-32A etc. are mixed with Hybrid Rice Combination, its hybrid vigour will obviously be better than by the correspondences of bright extensive 86 preparations and combine.
Compare with bright extensive 86 coordinate force in table 1 town extensive 98
2. disease resistance is strong.The Shan of extensive 98 preparations in extensive 98 high resistance to hoja blanca ，Yong towns, town is excellent 98, it is excellent 98 to assist, II excellent 98 etc. also shows as high resistance to hoja blanca; Bright extensive 86 high sense bacterial leaf-blights, excellent 86 with the Shans of bright extensive 63 preparations, assist excellent 86, II excellent 86 etc. also to show as the high bacterial leaf-blight of feeling.
3. compatibility is wide.The restorer bran point purple that the present invention is bred as, with this restorer and corresponding japonica rice material hybridization, hybrid F
1ripening rate is normal, and bright extensive 86 with the hybridization of these japonica rice materials, hybrid F
1ripening rate very low.
4. the comprehensive agronomy proterties is outstanding.The tillering ability in town extensive 98 is strong, and plant is short strong, and the leaf colour cast is dark, and sword-like leave is shorter, and canopy leaves is tall and straight, and functional period is long, and improving activity of root system is strong, and lodging resistance is good.Bright extensive 86 stem stalks are partially soft, and Ye Selve is light, and sword-like leave is partially long, and canopy leaves is hung down loosely, and lodging resistance is general.
The accompanying drawing explanation
Fig. 1 is the extensively breeding pedigree schematic diagram of the Indica Rice restorer of affine, bacterial blight-resisting of the present invention.
