A method for the selection and propagation of fine varieties of A. chinensis single plant-mother line selection

Abstract

The invention provides a seed breeding and expanding propagation method with combination of costustoot individual plant and mother line selection. The method comprises the steps of selecting a candidate group, performing vegetative propagation of an advantageous individual plant, carrying out isolated sexual reproduction of advantageous individual plant groups, performing mixed hybridization of advantageous individual plant groups and verifying. According to the new costustoot variety breeding method creatively provided by the invention, a new variety having stable inheritable character, high yield and high quality can be rapidly selected and bred; and the amount of the original seeds of the new variety is large and thus the method can be rapidly promoted; and according to the method, the new variety is selected and bred in combination with the evaluation on the appearance characteristic, the yield and the quality, so that the condition that the new variety can grow vigorously, and has high yield and high quality can be ensured.

Description

technical field [0001] The invention relates to a plant variety breeding method, and more specifically relates to a method for breeding and multiplying fine varieties of acacia single plant-mother line selection. technical background [0002] At present, most of the existing cultivars of Akiras in our country are mixed groups, and there are no new varieties available for production. The research on the breeding of improved varieties is still in its infancy, and there are no reports on the methods of breeding new varieties of Akiras. In the prior art, Muxiang is sexually propagated through seeds, and the excellent traits of the mother plant are prone to trait separation in offspring, but in this case, the asexual reproduction through buds can maintain the excellent traits of the mother plant, providing abundant material for the selection of parents Base. [0003] In the prior art, the selection of excellent traits of the taproot is generally firstly selected according to the...

Problems solved by technology

[0003] In the prior art, the selection of excellent traits of the taproot is generally firstly selected according to the traits of the above-ground part, and the seeds are collected in isolation during the flowering period, and then screened according to the appearance, yield and quality indicators of the taproot when harvesting. The primary selection is blind, and the workload of isolation is large, time-consuming and laborious. Expensive, and often leads to missed selection of individual plants that meet the breeding goals
