A kind of Lagerstroemia indica plant avoids male compartment isolation bagging hybrid breeding method

Abstract

The invention relates to a hybrid breeding method for plants of the genus Lagerstroemia without male compartment isolation and bagging, and belongs to the technical field of plant cultivation. The method comprises the following steps: 1. making a crape myrtle androgyne compartment isolator; 2. bagging; 3. pollination; 4. dismantling. The present invention has the following advantages: 1. Directly buckle on the flower buds with the "crape myrtle stamen and stamen compartment isolator", without peeling and emasculating the buds, and the operation is simple, which overcomes the defect that the emasculation isolation bagging method requires skilled operation skills; 2. Eliminate the manual operation of bud peeling and detasseling, which can reduce costs and overcome the defects of manual detasseling and higher cost; 3. It can avoid damage to flower organs in various parts, can ensure its normal growth and development, and overcomes the disadvantages of detasseling. Male isolation bagging method is easy to damage the defects of floral organs.

Description

technical field [0001] The invention relates to a hybrid breeding method for plants of the genus Lagerstroemia without male compartment isolation and bagging, and belongs to the technical field of plant cultivation. Background technique [0002] "Hubei Agricultural Sciences", Volume 49, No. 11, November 2010, recorded a research report by Wang Ruiwen, Yang Yanling, etc. on "Research on the Viability Changes of Lagerstroemia in Pollen and Receptivity of Stigma". Around 4:30, the flower buds are loose, the stigma is protruding, and the top is green without mucus; 5:30-6:00, the petals begin to unfold and reveal the anther; At 9:30, a large amount of mucus began to be produced, and the stigma was observed to be covered with pollen; at 16:00 in the afternoon, the calyx closed, and the stigma was still upright outside. On the second day of flowering, the calyx is completely closed, the curved top of the stigma is covered with yellow pollen, the color of the petals becomes lighte...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, the hybrid breeding of Lagerstroemia plants adopts the above-mentioned emasculation isolation bagging method, which has the following defects: 1, when carrying out hybrid emasculation, generally adopts the artificial emasculation method, which needs to be mastered to carry out; The operation is time-consuming and labor-intensive, and the production cost is high; 3. The work progress is slow and the efficiency is low; 4. It is difficult to operate the plants with small flowers, and it is easy to peel and damage the ovary
