Abstract
The invention discloses a hybrid seed production method for stevia rebaudiana. The method comprises the steps that firstly, cutting propagation is conducted on parent plants of the stevia rebaudiana, colonies which are consistent in genotype and reproduction characteristic are formed, the colonies serve as parent strains of hybrid seed production, two of the parent strains are planted in the same field in a lined and spaced mode, natural hybridization between the parent strains is conducted, and stevia rebaudiana hybrid seeds can be obtained. By means of the method, defects that judicious hybrid cannot be conducted on seedling colonies of stevia rebaudiana seeds, the colony segregation is large, and characters are not stable are overcome, and the excellent stevia rebaudiana hybrid seed combination which is comparatively stable in character can be provided.
Description
Technical field
a method for stevia hybrid seeding, relates to the seeding technique of stevia crossbreed, is a kind of method of stevia hybrid seeding in particular.
Background technology
the kind that current stevia uses is all the conventional variety adopting systematic breeding or filial generation isolation and selection to go out, and the technical merit of breed breeding is lower, seriously limits the development that stevia is produced.According to the genetic development of crops, adopt cross-breeding technology, utilize the hybrid vigour of a F1 generation can the advantage of comprehensive different stevia parent, increase substantially economic flow rate and the quality of stevia, bring new growth engines to seed industry simultaneously.
according to the method for general crops cross breeding seed, be by the seed sowing of Parent or seedling raising and transplanting in one piece of farmland, carry out mutual hybrid seeding, the hybrid seed producing F1 generation for the production of.If but the stevia seed seedling of Liang Ge colony carries out natural hybrization in field, not only have the phase mutual cross between two colonies, also have the selfing between the inner plant of colony, the population characteristics of its offspring is by disorderly and unsystematic, predictable stable character cannot be formed, also cannot be applied to production.
Summary of the invention
the object of the invention is to produce Problems existing for above-mentioned stevia crossbreed, propose a kind of solution of new stevia hybrid seeding.
the present invention is achieved in that
(1) set up parent's strain: in field, cottage propagation is carried out to the individual plant of stevia, form parent's strain that genotype is consistent with reproductive characteristic;
(2) hybrid seeding: by 2 different parent's strains by row alternate field planting in same field, carry out mutual natural hybrization, obtain stevia crossbreed.
beneficial effect of the present invention:
this case proposes with parent's strain of the mode crossbreeding of individual plant cuttage, plant all in a colony is all from a plant, not only hereditary capacity height is consistent, and, as a vegetative colony from same plant, each plant in colony is attending to anything else of former maternal plant, and reproductive characteristic can be considered an individual plant.Because stevia has the acarpous characteristic of selfing, so not only intragroup individual selfing can not be solid, between each individuality can not mating solid.Be planted in together by two different production of hybrid seeds parent strains, can not carry out mating solid between the flower of each colony inside, the plant between colony then can cross-fertile freely mutually, defines directed hybridization.The crossbreed of producing like this can keep the relatively stable of kind of property, the excellent proterties that different parent has can be combined by such hybridization, improves the output of F1 generation, quality and resistance, realizes high yield, stable yields and quality product matter.
Embodiment
a method for stevia hybrid seeding, comprises the steps:
(1) set up parent's strain: in field, cottage propagation is carried out to the individual plant of stevia, form parent's strain that genotype is consistent with reproductive characteristic;
(2) hybrid seeding: by 2 different parent's strains by row alternate field planting in same field, carry out mutual natural hybrization, obtain stevia crossbreed.
Claims (1)
1. a method for stevia hybrid seeding, is characterized in that, it comprises the steps:
(1) set up parent's strain: in field, cottage propagation is carried out to the individual plant of stevia, form parent's strain that genotype is consistent with reproductive characteristic;
(2) hybrid seeding: by 2 different parent's strains by row alternate field planting in same field, carry out mutual natural hybrization, obtain stevia crossbreed.
