Abstract

The invention relates to agriculture and can be used in the breeding of alfalfa. The purpose of the invention is to increase productivity. During hybridization of alfalfa, the upper part of the sail of a blossoming flower is removed from the mother plants, artificially tripping is pressed by pressing the calyx or the bottom of the boat, the spores are differentially destroyed by immersing the flowers for 1 to 2 hours in a hypotoxic water solution and then drying on the stigma is applied paternal pollen. 1 tab.

LU. ib of the invention - increased productivity of labor.

The method is carried out as follows.

In maternal plants, the upper part of the sail of a blossoming flower is removed, which, when tripping, hits the stigma, causes artificial tripping by pressing (tweezers or other object) on the base or bottom of the boat (while due to the shortened sail, the stigma of pesgik does not hit it). and the pellicle film, covering the stigma, is not damaged), produces a differential disintegration of osteal shock by shaving the flowers for 1-2 h into hypotonic pac iBop water (distilled, water-) bottom, rain, etc. .), and then cessation of exposure to water and drying of the stigma (after 15-30 minutes, depending on humidity and temperature of the surrounding air), apply Ogcowa pollen with a spatula and hang a label with HOMepo.vi.

Example. During the hybridization, varietal (Aledicago varia mart) varieties of Vega are used as mother plants.

The use of these operations on plants of this variety has significantly increased the efficiency of hybridization and labor productivity (see table).

The advantage of the proposed method is the reduction in the number of operations during castration, the addition of simple techniques, the preservation of high reliability of castration and the elimination of the closeness of the O1 seeds of self-pollination.
