Hybrid bitter gourd breeding process

Abstract

The hybrid biter gourd breeding process with No. 812 as female parent and No. 948 as male parent includes isolation, reasonably determining the seeding period difference between the female parent andthe male parent, determining the plant ratio between the female parent and the male parent, and determining the planting density. The hybrid biter gourd has the features of prematurity, high yield, good commodity character of fruit, wide applicability, etc.

Description

(1) Technical field [0001] The invention relates to the technical field of biological heterosis utilization, in particular to a breeding method for hybrid bitter melon. (2) Background technology [0002] Bitter melon is a cultivated species in the genus Momordica cucurbitaceae (Cucurbitaceae), and is an annual climbing herb. The formal name used at school is Momordica charantia L, another name is bitter gourd, and ancient name brocade lychee, leprosy grape. It is native to tropical Asia and is now widely distributed in tropical, subtropical and temperate regions. Bitter gourd has a long history of cultivation in my country and a vast area. It is mainly distributed in Guangdong, Guangxi, Hainan, Fujian, Taiwan, Hunan, Sichuan and other provinces (regions). It is rich in nutrition, unique in flavor, and has high medical and health care value. Consumers love it, and in recent years, it has been favored by consumers even more. The market demand, especially the demand in large a...

Problems solved by technology

However, in production in various places, bitter gourd is still dominated by mid-maturing and mid-late-maturing farm varieties and conventional varieties, which generally have shortcomings such as late maturity, low yield, poor commerciality, poor disease resistance, and poor stress resistance. The lack of a standardized production technology system and quality inspection system results in low seed yield and unstable quality, which affects the interests of producers and consumers

At present, some scientific research units have begun to pay attention to the selection and breeding of early-maturing varieties, and have successively bred a batch of early-maturing new varieties, but the application effect in production is not ideal. The contradiction between (reverse) properties, and the inability to solve large-scale hybrid seed production technology, it is difficult to provide sufficient hybrid commercial seeds for production
