Breeding technology of improved varieties of plum and apricot seedlings

Abstract

The invention relates to a breeding technology of improved varieties, in particular to a breeding technology of improved varieties of plum and apricot seedlings. The improved varieties of seedlings are cultivated by the following steps: breeding field selection, pre-sowing treatment and germination cultivation, scion grafting, post-grafting treatment and seedling outplanting. The pre-sowing treatment is sand storage lamination. The breeding technology of improved varieties of plum and apricot seedlings provided by the invention has the advantages of disinfecting through pre-sowing treatment, preserving the good and rouging and preventing and controlling diseases and insect pests in germination cultivation and post-scion treatment, and ensuring no virus in seedling production; by raising seedlings in nutrition pockets, the root systems of young seedlings are all in the nutrition pockets, and the whole pockets with soil are transplanted while transplanting, so that the survival rate is improved, and the average survival rate is 96% or more; the main root number of the root systems of the seedlings obtained by breeding is at least five, the average length of main root and lateral root is at least 5cm greater than that of the conventional seedling breeding, the stem width is 0.8 to 1.2cm, and the full bud number of a training belt is more than 10. The plum and apricot seedlings bred by the invention have developed root systems, are robust and non-toxic, and have high survival rate and early production period.

Description

technical field [0001] The invention relates to the technical field of seedling breeding, in particular to a method for breeding plum and apricot seedlings. Background technique [0002] The breeding of improved seedlings is the continuation of the work of species selection and an important link in the application of improved seeds to production, which has very important significance and far-reaching influence. If good varieties are not frequently selected, and reasonable breeding techniques and breeding systems are not adopted, it will result in mixed varieties and degraded species, which will not only fail to meet the production requirements, but even bring serious adverse consequences to production. [0003] Plum and apricot are both stone fruit seedling varieties native to China, and their propagation is mainly through grafting. In recent years, the regional development of these two seedlings has been rapid, and the demand for seedlings has increased significantly. How...
