Embodiment

[0022] Embodiment: the first step, the F1 generation obtains

[0023] Select the offspring SJ08-91-2-1 of the three camphor peppers collected in Hengdong County, Hunan Province as the female parent, and select the excellent red pepper parent material LS20 bred by Hunan Vegetable Research Institute (not limited to LS20, other excellent red pepper materials can also be used instead) as the male parent, and the F1 generation is obtained by crossing.

[0024] In the second step, the BC1 generation obtains

[0025] Plant 10 plants of the F1 generation obtained by crossing SJ08-91-2-1 and LS20 in a gauze shed, harvest the seeds of the F1 plants, and obtain the F2 generation; plant 50 F2 plants in the field, and select the F2 generation to synthesize The traits closest to the red pepper material LS20, the single plant with yellow mature fruit color and strong spicy taste was the female parent and LS20 was backcrossed to obtain the BC1 generation.

[0026] In the third step, the inb...

Abstract

A method of selecting an excellent yellow capsicum annuum resource material is provided. The method includes a first step of selecting an excellent capsicum chinense single plant and an excellent red pepper single plant and hybridizing to obtain an F1 generation, a second step of selfing to obtain an F2 generation, selecting a single plant comprehensive characters of which are approximate to those of the original red pepper material and fruit mature color of which is yellow and pungency of which is strong from the F2 generation, and backcrossing with the excellent red pepper material to obtain a BC1 generation, and a third step of selfing the BC1 generation to obtain an F2 generation of the BC1, selecting excellent yellow capsicum annuum single plants from the F2 generation of the BC1 and performing four-generation single plant selection to obtain a stable excellent yellow capsicum annuum inbred line. Compared with materials selected from common methods, the yellow capsicum annuum resource material selected by the method has obvious improvements in yields, quality, disease resistance, stress resistance, and the like, and has comprehensive characters reaching the red pepper level.

Description

technical field [0001] The invention relates to a method for breeding high-quality yellow pepper resource materials, belonging to the technical field of plant breeding. Background technique [0002] Pepper (Capsicum annum L.), a plant of the genus Capsicum in the family Solanaceae, is the vegetable that is second only to Chinese cabbage in planting area in my country. From the end of the 1970s to the beginning of the 1980s, pepper F1 seeds were widely planted in my country, and many local varieties of farm resources were gradually eliminated and disappeared. In particular, the area planted with yellow peppers was almost completely replaced by red peppers. In recent years, with the development of the pepper processing industry, the demand for yellow peppers has increased year by year. However, the remaining resources of yellow peppers are scarce, and the comprehensive characteristics of the resources are difficult to compare with the currently grown red peppers. The main perf...
