Breeding method of precocious waist-shaped loofah

Abstract

The invention discloses a breeding method for an early-maturing girdle-shaped loofah and belongs to the technical field of loofah breeding. In this method, Zhu Luffa No. 2 was used as the original resource, and the breeding objectives were girdle-shaped fruit, tender flesh, early and many female flowers, and strong continuous fruit-setting ability. After 10 generations, a high-generation inbred line Zhu A-01 was bred; Taking Zaoza 1 as the original resource, with the breeding goals of extremely early fruit maturity, strong disease resistance and low temperature tolerance, the high-generation inbred line Zhu B‑01 was bred after 12 generations; the high-generation inbred line Zhu A ‑01 was the female parent, and the advanced inbred line Zhu B‑01 was used as the male parent for cross breeding, and the first-generation hybrid Zhu Luffa No. 10 was obtained. This hybrid variety has a well-developed root system and strong growth potential. Both the main and side vines can produce melons. It matures very early and has a long continuous harvest period. In the early stage, each plant has 8 to 10 melons. The fruit is waist-shaped, with fine skin color and stress resistance. Strong, wide adaptability.

Description

technical field [0001] The invention relates to a breeding method for an early-maturing girdle-shaped loofah and belongs to the technical field of loofah breeding. Background technique [0002] Loofah is an annual climbing herb of Cucurbitaceae Luffa. There are 8 species. In my country, there are 2 species of common loofah and ribbed loofah. Among them, common loofah is distributed all over the country, and ribbed loofah is only planted in some places in the south. Loofah has a good health function. As people pay more and more attention to dietary health care, loofah, as a vegetable and health care dish with both medicinal and dietary needs, is constantly increasing, and the planting area is also expanding. [0003] In my country, loofah breeding started relatively late, and the breeding of new varieties of loofah has only been carried out in recent years. At present, there are few basic theoretical research and technical research on loofah genetics and breeding, and fewer ...

Problems solved by technology

However, it is not allowed to blindly introduce or try planting, it will cause the adaptability of loofah varieties to deteriorate, the pests and diseases will intensify, and the yield will decrease.

[0004] At present, most of the loofah varieties planted in northern my country have problems such as easy aging, low yield, late maturity, low female flower rate, no disease resistance, stress resistance, and poor quality. The favorability of the attribute is higher than that of the loofah with green skin, waist-shaped melon strips, well-proportioned, early maturity, and moderate length, so plant this variety of loofah
