Purification and rejuvenation method of long horn pepper variety

Abstract

The invention relates to a method for purifying and rejuvenating a long-horned pepper variety, comprising the following steps: A. selfing a single plant of long-horned pepper to select two varieties with hairy stems and hairless stems; B. crossing the two varieties to obtain F1 Generation seeds; C, selfing the F1 generation single plant, and selecting the twisted-handled pepper as the F2 generation seed; D, selfing the F2 generation individual plant, and selecting the capsicum with the leaf size above the branch of the plant similar to the leaf below the branch Make F3 generation seeds; E. Self-cross the F3 generation single plant, select the chili peppers that are branched at 30-60 degrees as the F4 generation seeds; F, self-seed the F4 generation single plants, and select the peppers with the remaining peppers and no wrinkled peppers Make F5 generation seeds; G. Self-cross the F5 generation single plant, and select the highly lignified peppers with branches above the branches as F6 seeds; H. Continuously self-seed the F6 generation single plant for 3 to 4 generations, and purify the long-horned pepper parent Inbred seeds. The invention adopts self-crossing observation of a single plant, and purifies a long-horned pepper variety with strong stress resistance, high yield and stable properties according to the advantages of different characteristics of the pepper.

Description

technical field

[0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a method for purifying and rejuvenating pepper varieties. Background technique

[0002] Longhorn peppers contain more than a dozen kinds of amino acids and multivitamins. The amino acid content of dried peppers is 11.27%, vitamin C is 71mg / kg, total sugar is 13.8%, protein is 13.56%, capsaicin is moderate, and the main indicators are better than similar products. It is well-known both at home and abroad for its thin flesh, bright red color, moderate spicy taste, spicy and sweet, strong fragrance and rich nutrition. The whole growth period of Longhorn Pepper is about 175 days. The natural plant height in the field is about 80 cm. The plant height of early sowing and early planting with soil fertilizer can reach 130 cm, and the plant height of late sowing and late planting is only 30 cm. It is usually sown at the end of February to early March, transplanted in...

[0020] The method for purifying and rejuvenating the long-horned capsicum variety comprises the following steps:

[0021] A. Collect some long-horned peppers for self-breeding observation, and select two pure varieties of long-horned peppers with hairy stems and hairless ones. Among them, the hairless peppers have darker leaves and darker fruits. Red, the fruit surface is bright, but the disease resistance is poor. The leaf color of the hairy pepper is light, the fruit color is medium red, and the brightness is not as good as that of the hairless species, but the disease resistance is strong. After the two varieties are crossed, the disease resistance is strong. Glossy hybrid capsicum seeds.

[0022] B. Hybridize the long-horned pepper seeds with hairy and hairless stems on a single plant to obtain F1 generation hybrid seeds. The F1 generation hybrid seeds inherit the strong disease resistance of hairy peppers and inherit the fruit of hairless peppers The advantages of deep r...
