Soybean cultivation by distant grafing and vegetative hybridization

Abstract

A method for culturing the new variety of soybean by distant grafting and asexual hybridization includes such steps as providing strong yam stem (or castor stem) stock, providing soybean sprout as scion, grafting the scion onto said stock, culturing, natural blossoming and fruiting, collecting the seeds, natural sowing, choosing the plants with obvious character variation, collecting their seeds, sowing, and repeating the steps until the chosen characters have stable inheritance. Its advantages are high yield and high resistance to diseases.

Description

technical field [0001] The present invention relates to obtaining hybrids by asexual hybridization of Dioscoreaceae yam, Euphorbiaceae castor and leguminous common soybean, cultivating, selecting and creating new soybean varieties. Distant grafting variation is the resistance variation induced by grafting growth stress. Its main significance is that it can break the restriction of intraspecific genes and provide new materials for artificial selection. Every part of a plant organism has the ability to restore and transmit its parental heredity, and asexual hybridization is to change the heredity of its offspring in time through the interaction between living substances. Background technique [0002] Soybeans originated in my country. Its ancestor, the wild soybean Glycinesoja Sied.et Zucc, is widely distributed in my country and has a history of about 3000 years ago. Many ancient books in our country once called soybeans as bean. In the "Book of Songs", there is a record: "...
