Abstract
The present invention relates to a method for breeding a kenaf cytoplasm sterile line. The method takes the kenaf wild species UG93 or the filial generation of the UG93 as the female parent and the kenaf cultivar as the male parent to carry out saturated backcross. The wild-abortive cytoplasmic male sterile line represents male sterility and has the characters which are similar to those of the male parent and are neatly conformed. The backcrossing male parent is the male sterile maintainer line. The male sterile line which is bred in such a way naturally hybridizes with other kenaf cultivars so as to breed the cross combination with strong advantages.
Description
Technical field:
The present invention relates to breeding method, specifically is a kind of selection of bluish dogbane cytoplasmic male sterile line.
Background technology:
Bluish dogbane claims " mestha " again, is the annual phloem fiber crop of Malvaceae Hibiscus.Because of bluish dogbane serves as the cultivation purpose with results phloem fiber or stem stalk, heterosis rate is up to 35%～40%, and the bluish dogbane heterosis utilization is the main goal of attack of domestic and international bluish dogbane breeding for a long time.Hemp Inst., China Academy of Agricultural Sciences has invented bluish dogbane chemical emasculation cross breeding method, and has used in the bluish dogbane breeding through research for many years.But because of bluish dogbane is an indefinite inflorescence, needs repeatedly dispenser, and influenced insect pollination after the dispenser, need artificial pollination.For saving cost, have to promote aborning F2 generation (second filial generation).But F2 is irregular for plant, and heterosis rate obviously reduces, so the hybridization bluish dogbane area of promoting in bluish dogbane produces is very limited so far.Therefore, seed selection bluish dogbane cytoplasmic male sterile line is to utilize heterotic key problem in technology on bluish dogbane produces.
Summary of the invention:
The objective of the invention is to overcome the defective that prior art exists, a kind of method of seed selection bluish dogbane cytoplasmic male sterile line is provided.
The present invention is that the filial generation with bluish dogbane wild species UG93 or bluish dogbane wild species UG93 is a female parent, with the bluish dogbane cultivar is that male parent is carried out saturated backcrossing, it is similar to male parent therefrom to select proterties, neat and consistent, and show male sterile Yebai cytoplasmic male sterile line, its used male parent of backcrossing is male sterility maintainer line.
The present invention measures coordinate force with a plurality of cultivars when backcrossing, each selects coordinate force height, proterties similar to male parent from generation to generation, and the indehiscent male sterile plant of flower pesticide continues to backcross, while male parent bagging selfing, and backcrossing was not less than for 5～6 generations.
The present invention adopts and does maternal bluish dogbane wild species UG93 or the filial generation of bluish dogbane wild species UG93, all heredity has the cytoplasm of bluish dogbane wild species UG93, with this cytoplasm is donor, is the cell nucleus donor with common bluish dogbane cultivar (being) again, and consequent nucleo-cytoplasmic interaction causes male sterile.
Practicality of the present invention is: bluish dogbane wild species UG93 cytoplasmic male sterile line and other bluish dogbane cultivar natural crossing combining go out strong advantage hybrid combination, and breeding cost is low, make in the bluish dogbane production to utilize F1 to become possibility for hybrid vigour.Because of bluish dogbane is the raise crop in " south plant north transfer ", the Yangtze river basin and to the north of the area can not reserve seed for planting naturally, annually need from south China (mainly being Guangxi) to transfer kind, be easy to control hybrid seed production.The bluish dogbane hybrid seed not only can be promoted to the whole nation, and can utilize the foundation of WTO rule and China-free trade area, Southeast Asia, and to state's outer vent, economic benefit is very remarkable.

Embodiment 2:
With the stingless first familiar generation of male sterile bluish dogbane wild species UG93 * golden light is female parent, with isolated full blade profile strain in the purple of bluish dogbane cultivated species Java is that L23 is a male parent, adopt saturated method of backcrossing, select UG93 cytoplasmic male sterile line L23A and maintenance line L23B thereof.
Embodiment 3:
With the stingless first familiar generation of male sterile bluish dogbane wild species UG93 * golden light is female parent, and rich No. 1 is male parent with bluish dogbane cultivated species Guangdong, adopts saturated method of backcrossing, and selects rich No. 1 A in UG93 cytoplasmic male sterile line Guangdong and rich No. 1 B in maintenance line Guangdong thereof.
Embodiment 4:
With bluish dogbane wild species UG93 * bluish dogbane cultivated species Laiyang bluish dogbane first familiar generation is female parent, and red No. 3 is male parent with bluish dogbane cultivated species good fortune, adopts saturated method of backcrossing, and selects red No. 3 A of UG93 cytoplasmic male sterile line good fortune and red No. 3 B of maintenance line good fortune.
Embodiment 5:
With rich No. 1 first familiar generation in bluish dogbane wild species UG93 * bluish dogbane cultivated species Guangdong is female parent, is for No. 917 male parent with the bluish dogbane cultivated species, adopts saturated method of backcrossing, and selects UG93 cytoplasmic male sterile line 917A and maintenance line 917B.
Claims (2)
1. the selection of a bluish dogbane Yebai cytoplasmic male sterile line, it is characterized in that with bluish dogbane wild species UG93 or heredity the cytoplasmic filial generation of bluish dogbane wild species UG93 being arranged is female parent, with the bluish dogbane cultivar is male parent, carry out saturated backcrossing, it is similar to male parent therefrom to select proterties, neat and consistent, and show male sterile Yebai cytoplasmic male sterile line, its used male parent of backcrossing is male sterility maintainer line.
2. according to the selection of the described bluish dogbane Yebai cytoplasmic male sterile line of claim 1, when it is characterized in that carrying out saturated backcrossing, be to measure coordinate force with a plurality of cultivars simultaneously, each selects coordinate force height, proterties similar to male parent from generation to generation, and the indehiscent male sterile plant of flower pesticide continues to backcross, male parent bagging selfing simultaneously, backcrossing was not less than for 5～6 generations.
