Embodiment 1

[0032] The breeding method of the capsicum stable genetic inbred line with high red pigment content and not easy to fade in the present invention specifically comprises the following steps:

[0033] 1. The visual inspection primary selection method includes the following steps:

[0034] (1) In the field breeding field, select the basic material capsicum fruit with high yield potential and disease resistance, make it dehydrated and in a semi-dry state, and the water content of the fruit is less than 25%;

[0035] (2) According to Figure 1-Figure 5 According to the color standard, the red-black red pepper material of the exocarp is selected; meanwhile, the red-black red pepper material of the endocarp is selected.

[0036] 2. Pepper Skin Thickness Screening Method

[0037] According to step 1 visually inspecting the chili material selected by primary selection, carry out the following steps:

[0038] (1) Peppers are dried until the moisture content is <8%;

[0039] (2) Take...

Abstract

The invention provides a method for breeding a hot pepper stable inheritance selfing line with high haematochrome content and difficult to fade. The method mainly comprises the steps of (1) primarily selecting through visual observation; (2) screening the thickness of hot pepper peels; (3) finely selecting through spectrophotometer; (4) finally selecting materials difficult to fade; (5) performing circulating polymerization selection. The selfing line bred by adopting the breeding method has high level and excellent target character on fading difficulty, and the bred selfing line can be directly used for combination breeding of hybrid combination.

Description

technical field [0001] The invention belongs to the technical field of breeding of new plant varieties, and in particular relates to a method for breeding a stable hereditary capsicum inbred line with high content of red pigment and not easy to fade. Background technique [0002] The red pigment extracted from capsicum can be widely used in food, medicine, health care, cosmetics and other fields, and can be eaten in unlimited quantities. Pepper has ranked first in the planting area of ​​vegetables in China, and plays an important role in agriculture and even the entire national economy. However, since most of the germplasm resources with high capsanthin content come from abroad, and capsanthin is formed from compound pigments such as capsanthin, capsanthin and zeaxanthin, it is a comprehensive trait of polygenic inheritance. Although breeders try to breed the first generation of capsicum hybrids with high red pigment content, it is difficult to effectively select their gene...
