Problems solved by technology

[0005] At present, in the production of fresh sheep's horn peppers and ox horn peppers in my country, the pepper varieties used have better nutritional quality and flavor quality, but the commodity quality is poorer, mainly manifested in the fruit with large head and small tail, relatively curved, and wrinkled fruit surface. The fruit is flat, which seriously affects the commercial value of pepper

Embodiment 1

[0024] (1) Luojiao No. 2 pepper with poor commodity quality (large fruit head and tail, relatively curved, wrinkled fruit surface, flat fruit, etc.) F 1 generation, and then the F 1 Backcross 2 times to obtain the BC2 generation, and then the size of the head and tail of the fruit is uniform (the specific index is: when 1 / 2 the fruit length, the fruit thickness is 100% of the fruit top thickness, and when 4 / 5 the fruit length, the fruit thickness is 100% of the fruit thickness. 100% of top thickness), fruit straight, smooth fruit surface, thin cylindrical fruit, etc., select its offspring, select 18 plants that meet the target and carry out single plant retention; plant these seeds respectively, and continue to use The fruit head and tail are uniform in size, the fruit is straight, the fruit surface is smooth, and the fruit is thin and cylindrical. In this way, after three generations of systematic breeding, a high-quality parental inbred line was selected and named as self-c...

Embodiment 2

[0028] (1) American Big Jim with poor product quality (large fruit head and tail, relatively curved, wrinkled fruit surface, flat fruit, etc.) Hunan Guangpijiao with smooth surface, cylindrical fruit, etc.) was used as the male parent to obtain F 1 generation, and then the F 1Backcross once to obtain the BC1 generation, and then the size of the head and tail of the fruit is uniform (the specific indicators are: the fruit thickness is 95% to 100% of the fruit top thickness at 1 / 2 fruit length, and the fruit thickness at 4 / 5 fruit length 88~95% of the thickness of the top of the fruit), straight fruit, smooth fruit surface, thick and long cylindrical fruit and other high-quality goals, select its offspring, select 8 plants that meet the target, and carry out single-plant reserved seed; These seeds were planted separately, and the selection was continued with the goals of uniform fruit head and tail size, straight fruit, smooth fruit surface, thick and long cylindrical fruit, et...

Abstract

The invention relates to a method for planting hot pepper, which comprises that using pepper as mother and father to be crossed; using selection method to plant a better parental generation self-cross system; using pepper as mother and using pimento as father to be crossed; using selection method to plant another better parental generation self-cross system; using said two self-cross systems as parents, using hybrid technique to plant the hot pepper. The inventive hot pepper has uniform size and beautiful appearance, while the price is 0.2-0.3yuan higher than other kinds and each unit field can generate 1500kg.

Description

technical field [0001] The invention belongs to the technical field of crop breeding, in particular to a method for breeding high-quality pepper varieties. Background technique [0002] Capsicum is one of the main vegetable crops in my country and plays an important role in the vegetable industry. Pepper production has become an important part of the three-high agriculture in many provinces and cities in my country, and has become one of the pillar industries in many cities and counties. [0003] In my country's production, peppers have long been divided into sheep horn peppers, ox horn peppers, Chaotian peppers, thread peppers, and sweet peppers according to their fruit properties; according to their uses, peppers can be divided into two types: fresh food and processed. [0004] Pepper quality includes commodity quality, nutritional quality and flavor quality. Commodity quality mainly includes the appearance of the fruit, which determines the commercial value of peppers; ...
