Breeding method of powdery-mildew-resisting cannonball-shaped white bitter gourd variety

Abstract

The invention discloses a breeding method of a powdery-mildew-resisting cannonball-shaped white bitter gourd variety and belongs to the technical field of bitter gourd breeding. According to the breeding method, a powdery-mildew-resisting variety, a heat-resisting variety, a white pericarp variety, a short conical variety, a short-rod-shaped variety and an early maturing variety are used as parents, are subjected to cross breeding, composite cross polymerization and multi-generation back-cross, and are subjected to multi-generation powdery-mildew-resisting identification, heat resistance detection and agricultural and yield property screening to culture the bitter gourd variety with powdery-mildew-resisting performance, good heat resistance, a white cannonball shape, alternated rounded grain bulges and short longitudinal bulges and early maturing performance; the variety has good peel color and luster, fruit pulp is thick, crispy and tender and juicy and the bitter taste is relativelylight; when the variety is planted, the utilization of pesticide can be reduced and the income of farmers is increased.

Description

technical field [0001] The invention belongs to the field of bitter gourd breeding, in particular to a breeding method for powdery mildew-resistant cannonball-shaped white bitter gourd varieties. Background technique [0002] Momordica charantia( Momordica charantia L.) is a vine herb belonging to the family Cucurbitae (Cucurbitaeae). It originated in the center of India-Myanmar. It is widely distributed in subtropical, tropical and temperate regions. It has been cultivated in my country for more than 500 years since the Southern Song Dynasty. Now Guangdong, Guangxi, Fujian , Sichuan and other places have extensive cultivation. In recent years, due to people's continuous understanding of the edible value of bitter gourd and the development of its medicinal functions, the bitter gourd industry in my country has developed rapidly, and the cultivated species and planting area are also increasing, and it has become a promising melon vegetable. . [0003] The summer temperature ...

AI Technical Summary

Problems solved by technology

At present, there are few studies on the breeding of powdery mildew resistance in bitter gourd breeding. Therefore, the powdery mildew resistance traits are better applied to the field of bitter gourd breeding, and a new variety of bitter gourd that is resistant to powdery mildew and has good heat resistance can be reduced. The use of pesticides can increase the output of bitter gourd, increase farmers' income, and bring huge economic benefits to farmers
