A kind of breeding method of hybrid bitter gourd

Abstract

The invention relates to a breeding method of hybrid bitter gourd, which adopts 812 as the female parent and 948 as the male parent, through isolation, reasonably determines the sowing time difference, plant number ratio and planting density of the parental parents, and prepares hybrids. The invention has the characteristics of outstanding early maturity, high and concentrated early yield, good high yield, etc., and the cultivated melons have beautiful shape and good commercial properties. Field experiments have proved that this hybrid has the characteristics of early maturity, high yield, good fruit commodity traits, and wide adaptability.

Description

technical field [0001] The invention relates to the technical field of biological heterosis utilization, in particular to a breeding method for hybrid bitter melon. Background technique [0002] Bitter gourd belongs to the cultivated species in the genus Bitter gourd of 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 litchi, 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 ...

AI Technical Summary

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
