The invention discloses a kind of method using the perennial feeding Job's tears of wild Job's tears seed selection.The step of this method includes " to being selected in the sexual growth of individual plant and the specific trait in asexual growth stage in 1 year; select and identify twice ", i.e. in Jinghong City, during annual short-day, in the sexual growth phase of wild Job's tears, first time selection is carried out to specific trait, harvest after seed, in the long-day, quick asexual propagation amplifies colony, then second of selection is carried out to specific trait.The present invention opens wild Job's tears utilization of resources new way；Make full use of wild Job's tears can generative propagation can invent two stage selection method for specific individual plant the characteristics of vegetative propagation again；With reference to the climatic characteristic and short day crop growth-development law of Jinghong City, the back-and-forth method for vegetative growth phase and generative growth phase different target character has been invented.The selection of objective trait twice is carried out in 1 year to same individual plant, selection pressure and efficiency of selection is improved, accelerates breeding process. |
