Seed breeding method for high-yield and high-quality downward cluster pepper

Abstract

The invention discloses a seed breeding method for high-yield and high-quality downward cluster pepper. The seed breeding method comprises the following steps of selection and breeding of a female parent: selecting a capsicum frutescens female parent of an upward cluster pepper variety and a Weiyuan seven star pepper male parent of upward cluster pepper variety to hybridize, planting, selfing, reserving seeds, selfing next generations, and repeating, wherein a variety which has optimum matching ability and of which the spicy degree meets the seed breeding requirement is selected, and is named as the capsicum frutescens female parent; selection and breeding of a male parent: selecting a xanthoxylum piperitum female parent of a downward cluster pepper variety and an IIN cluster downward pepper male parent to hybridize, planting, selfing, reserving seeds, selfing next generations, and repeating, wherein a variety which has optimum matching ability and of which the quality meets the seed breeding requirement is selected, and is named as the xanthoxylum piperitum male parent; hybridizing and grouping: hybridizing the capsicum frutescens female parent and the xanthoxylum piperitum male parent, planting, selfing, reserving seeds, and selfing next generations, wherein a variety which has optimum matching ability and of which the spicy degree, quality and oil content meet the requirements is selected, and is determined as downward cluster pepper; spraying a humic acid active liquid fertilizer to leaves of the downward cluster pepper, and planting, so as to obtain the high-yield and high-quality downward cluster pepper.

Description

technical field [0001] The invention belongs to the technical field of agricultural breeding, and in particular relates to a breeding method for downward clustered capsicum with high yield and high quality. Background technique [0002] Capsicum is a kind of flavor vegetable that people like, and it is favored by consumers because of its unique spicy property. The pungent taste in chili mainly comes from capsaicinoids. Capsaicin is one of the important indicators to evaluate the quality of pepper fruit. At the same time, as a secondary metabolite, capsaicin is widely used in many fields such as food additives, biological pesticides, antibacterial and analgesic drugs, and tear gas bombs. Capsicum is a species under the genus Capsicum in the family Solanaceae, and can be divided into cherry peppers, cone peppers, clustered peppers, long-horned peppers and sweet bell peppers, among which clustered peppers are the hottest.

Problems solved by technology

[0003] The spiciness of Chaotian clustered peppers is high. The traditional clustered peppers are in the shape of the sky. The fruit is exposed on the leaves. When encountering high temperature, sun exposure, sunburn is more serious, and it will cause other diseases, which seriously affects the yield of Chaotian clustered peppers. and quality, the output per mu is only 1000-1500 kg, so it is particularly important to improve the yield and quality of clustered peppers

[0004] However, there are also some reports on the research on the breeding of clustered peppers

Chinese patent CN 104160944A discloses a method for breeding small peppers clustered with hanging handles. The male sterile source is tested with Weiyuan Qixing pepper and Qin pepper respectively to obtain the female parent and male parent, and then the female parent and male parent are crossed. In this cross hybridization, clustered small peppers with hanging stalks are obtained. The clustered small peppers with hanging handles are downward clustered peppers. Handled pepper is used as the basic material for breeding. The prepared clustered pepper solves the problem of sunburn and maintains the spiciness, but the stress resistance and stability of the clustered pepper need to be improved
