Problems solved by technology

[0008] As a conventional variety, loofah has wide adaptability, but its disease resistance is extremely poor. The output in the year when the disease is prevalent is only a few hundred catties, and it is difficult to apply it in production in many areas.

Embodiment Construction

[0023] Observation found that the variety Yamei green loofah has good early maturity, 57 days from sowing to first harvest, medium seedling potential, good fruit setting, high yield, good heat resistance, and well-proportioned commercial melon strips. After screening, it was selected as the female parent, and at the same time, the Wanbao loofah, which was cultivated by Shandong Shouguang Ousheng Seed Company, was selected as the male parent for hybridization with it. Due to its high yield, strong resistance and excellent quality, it is suitable for greenhouse planting. Excellent economic benefits. The hybrid progeny was backcrossed with Wanbao loofah for 2 generations and selfed for 4 generations to produce intermediate self-crossed B1. B1 has the characteristics of high yield and disease resistance, but poor combining ability. The high-generation inbred line Wanbao loofah with good economic traits and strong combining ability was crossed with B1 as the female parent, and ...

Abstract

The invention provides a breeding method of a towel gourd with strong resistance. The breeding method is characterized by comprising the following steps: (1) breeding a midbody selfing line B1; (2) breeding a high-generation selfing line B2J; (3) breeding a novel species of towel gourd; (4) processing the seeds; (5) inoculating pathogen; (6) screening the excellent seedlings. The obtained novel species of towel gourd has the advantages of good fruit bearing performance, high yield, and heat resistance. Through the hybridization among different species, the towel gourd has the characteristics of strong resistance, excellent quality, and high comprehensive profit. The economic profit of greenhouse plating is very good, and the towel gourd has a wide market prospect. The provided breeding method has the advantages of rapidness, stable effect, and strong operability.

Description

technical field [0001] The invention belongs to the technical field of agricultural seed breeding, and in particular relates to a high-efficiency breeding method for loofah with strong resistance. Background technique [0002] Loofah belongs to the cucurbitaceae plant of dicotyledonous plants, and is used as medicine with ripe fruit, fruit network, leaves, vines, roots and seeds. Loofah has high medicinal value and can be used all over the body. All kinds of nutrients contained in luffa are higher in melon food, and the materials such as contained saponins, luffein, lymphatic temperament, wood glue, citrulling, xylan and interferon have certain special effects. It originated in tropical Asia and is native to Indonesia (otherwise, it is native to India). It was introduced into China around the Song Dynasty and became a vegetable that people often eat. At present, there are mainly two kinds of loofahs for vegetables, namely ordinary loofahs and ribbed loofahs. The former i...
