A kind of breeding method of fruit type yellow bell pepper

Abstract

The invention relates to the technical field of plant breeding and in particular relates to a breeding method of fruit type yellow pimentos. According to the breeding method provided by the invention,a pimento nucleus male sterile breeding technology is utilized, and a pimento nucleus male sterile line AB91 and resources with a yellow color, a sweet and crispy fruit taste and good quality are subjected to hybridization, selfing, test crossing and sister crossing; in a breeding process, nutritional quality (mainly comprising soluble sugar content and Vc content) and commodity quality of different resources are identified and screened through a method combining sensory quality evaluation and physicochemical analysis, so that a sterile line and a selfing line, which are yellow and have highsoluble sugar content and Vc content, are bred; the sterile line is hybridized to breed the fruit type yellow pimentos which have high soluble sugar content and Vc content, are yellow and can be eatendirectly.
