Hybrid breeding method for low-browning towel gourd

Abstract

The invention discloses a hybrid breeding method for a low-browning towel gourd. A high-generation inbred line LWB-02 with genetic stability is obtained as a female parent through six-generation single-plant inbred breeding of a Baiyushuang towel gourd, a high-generation inbred line LJ-01 with genetic stability is obtained as a male parent through six-generation single-plant inbred breeding of a Yulu towel gourd, and a hybrid variety Yulong is obtained through hybridization. The new hybrid variety obtained through the hybrid breeding method disclosed by the invention is white and shiny in towel gourd skin, compact in towel gourd flesh, and heavy in single towel gourd weight; the problem that the towel gourd flesh of a common towel gourd is generally easy to brown in the processes of transportation, cooking and processing is solved; the internal quality of the towel gourd is improved, and the high-quality requirements of consumers on the towel gourd are met. Meanwhile, after the screened non-browning inbred line LJ-01 is hybridized with other materials as the male parent, the browning degree of hybrid progeny can be significantly reduced, so that the inbred line LJ-01 can be utilized as a core material for breeding low-browning varieties.

Description

technical field [0001] The invention belongs to the technical field of loofah hybrid breeding, in particular to a hybrid breeding method of a low-browning common loofah variety. Background technique [0002] Loofah is an annual climbing herb of Cucurbitaceae, and it is divided into two types: ordinary loofah and ribbed loofah. Loofah not only contains a variety of nutrients needed by the human body, but also contains a variety of medicinal chemical components, which have the functions of anti-emergency, enhanced immunity, sedative and anti-inflammatory, antioxidant and anti-virus. The demand for loofah is increasing, and the cultivation area is expanding. [0003] The breeding work of loofah started late, and most of the local varieties with excellent performance were cultivated in production. Due to long-term selfing, the uniformity of these varieties decreased and their excellent characters gradually deteriorated. In recent years, breeders from all over the world have cu...

AI Technical Summary

Problems solved by technology

[0004] During the transportation and cooking process of loofah, due to mechanical damage to the tissue, its pulp is prone to browning, resulting in a decrease in the sensory, taste and intrinsic nutritional value of the product, making it difficult to meet consumers' high-quality requirements for loofah. This has become a loofah An important issue in consumption

In recent years, my country's Taiwan region has begun to pay attention to the breeding and basic research of low-browning or non-browning ribbed loofahs, but there are few reports on the breeding of low-browning common loofahs at home and abroad.
