Abstract

The invention relates to a selective breeding and propagating method of a plant, particularly relates to a selective breeding and propagating method of a capsicum, belonging to the technical field of plant breeding. Compared with the existing selective breeding technology of a male sterile line of a capsicum, the method has the advantages that the breeding procedure is simple and convenient, the breeding target character and procedure are controllable, the sterile plant rate and the sterile degree are high, and the breeding efficiency is enhanced. A new approach is developed for capsicum heterosis utilization, selective breeding of a leaf color marked sterile line, rapid purity identification of hybrid F1-generation seeds, and the like.

Description

technical field

[0001] The invention relates to a plant selection and breeding method, in particular to a pepper selection and breeding method, and belongs to the technical field of plant breeding. Background technique

[0002] Studies have shown that there is obvious heterosis in hybrids among pepper varieties. The ways to utilize heterosis in pepper include artificial emasculation interspecific hybridization, double-cross, three-cross and male sterile line (male sterile dual-purpose line hybrid seed production, cytoplasmic male sterile line seed production) seed production, chemical detasseling Androgen seed production. Among them, there are disadvantages such as environmental pollution and low purity of hybrids in chemical castration seed production. Therefore, artificial castration and male sterile line seed production are mainly used in the world. The disadvantages of artificial detasseling are: the stamens of the female flower buds must be removed during seed product...
