Method for breeding good white chili breeding material

Abstract

The invention discloses a method for breeding high-quality white pepper breeding materials. The method includes the following steps: the first step is to select a single plant of green pepper and cross the single plant of white pepper to obtain the F1 generation; the second step is to use the obtained The F1 generation is self-crossed to obtain the F2 generation. Select an excellent individual plant in the F2 generation with white fruit and comprehensive traits close to the green pepper, and then backcross with the white pepper to obtain the BC1 generation; the third step is to self-cross the BC1 generation to obtain the BC1 F2 From these generations, select excellent white pepper plants, and carry out seven generations of self-purification to obtain stable and excellent white pepper inbred lines. In the present invention, the excellent genes of the white pepper and the green pepper are aggregated together by crossing, separating, and backcrossing the green pepper and the white pepper, and the selected white pepper material not only has the spicy taste and quality of the white pepper, but also has the characteristics of the green pepper. Fruit-setting, stress resistance and high yield. In order to meet the needs of the market, an effective breeding method is provided for the breeding of fine white pepper varieties.

Description

technical field [0001] The invention relates to a method for breeding high-quality white pepper breeding materials, belonging to the technical field of plant breeding. Background technique [0002] There are many types of peppers, which can be divided into green peppers, white peppers and peppers of other colors according to the color of the fruit. White peppers have a good surface gloss, fresh taste, and spicy taste. They have specific consumer groups. In recent years, the market for white peppers Prices are often higher than ordinary green peppers, and vegetable farmers are increasingly motivated to grow white peppers. The original white peppers are mainly some local varieties, such as the white peppers in Longyou County, Zhejiang Province. Due to the late maturity, low yield and poor stress resistance of these local varieties, they cannot meet the requirements of modern facility cultivation. According to the traditional practice, the breeding materials of white pepper ar...

Problems solved by technology

The original white peppers are mainly some local varieties, such as the white peppers in Longyou County, Zhejiang, etc., because these local varieties have late maturity, low yield, and poor stress resistance, they cannot meet the requirements of modern facility cultivation.

According to the traditional practice, the breeding materials of white pepper are purified from these local varieties, and the green and white of the pepper fruit color are recessive, and the white is controlled by a recessive gene, which makes the existing white pepper resources very scarce. Therefore, the genetic background of the white pepper breeding material obtained by the traditional method is very narrow, in order to obtain excellent white pepper breeding material for selection, the research of the present invention is carried out
