Disease-resistant seedling growing method for indoor identification of single plant at seedling stage of wheat pot transplantation

Abstract

The invention discloses a disease-resistant seedling growing method for indoor identification of a single plant at the seedling stage of wheat pot transplantation. The disease-resistant seedling growing method comprises the following steps: seed selection and pot preparation; pot body sowing; intelligent greenhouse control; indoor pathogenic bacteria inoculation of the single plant at the seedlingstage; indoor identification of the single plant at the seedling stage; pot body transplantation; conventional seedling growing. With the adoption of pot body planting, intelligent greenhouse control, indoor pathogenic bacteria inoculation of the single plant at the seedling stage, uniform and consistent conditions are provided for the occurrence of wheat diseases, namely, uniform and consistentselection pressure is provided for selection on the disease-resistant single plant, so that the phenomenon of inconsistent disease onset conditions, non-uniform disease perception and the like cannotoccur, therefore, the selection on the disease-resistant single plant is more facilitated, the consistency of selected pressure for disease resistance is easily controlled, and the wheat disease resistance identification is not limited by time or identified wheat disease type; the disease-resistant seedling growing method is simple, easy to learn and use, accurate in identification and short in identification cycle; after identification, the disease-resistant single plant is transplanted into a test field through a pot body, so that the test area is greatly reduced, the workload is reduced, the survival rate is ensured, and no slow seedling phenomenon exists.

Description

technical field [0001] The invention relates to the technical field of wheat breeding, in particular to a method for indoor identification and disease-resistant breeding of a single plant at the seedling stage of wheat pot transplanting. Background technique [0002] The current method used in wheat disease resistance breeding is F in the field 2 , F 3 , F 4 …For field selection of new strains for disease resistance, that is, to select disease-resistant individual plants, it requires a large test area and field individual plant groups, which requires a large amount of labor, and the selection pressure consistency of field disease resistance selection is difficult to control . Contents of the invention [0003] The purpose of the present invention is to provide a method for indoor identification and disease-resistant breeding of single wheat plants at the seedling stage of transplanting wheat pots to address the above-mentioned deficiencies in the prior art. [0004] Te...
