Problems solved by technology

[0004] Pepper planting in my country is mainly faced with many problems such as single variety structure, increasing pest damage, low benefit, poor storability of products, and short shelf life. The cultivation of new varieties with multi-resistance, high yield and high quality suitable for cultivation under different ecological conditions is the current domestic Main Objectives of Pepper Breeding

Embodiment 1

[0031] A kind of capsicum breeding method, comprises the steps:

[0032] (1) Select a pepper variety with strong stress resistance (Zhejiao No. 1) as the female parent, and a pepper variety with high yield (Jijiao No. 8) as the male parent;

[0033] (2) In the afternoon before flowering, the female parent (Zhejiao No. 1 pepper) was artificially detasseled, and the viability of the pollen during the flowering period and the pollination of the stigma were measured;

[0034] The pollen viability of artificially emasculated flowers is measured, stained with TTC solution, and samples are taken from the field every 3 hours starting from 8:00 in the morning, and the pollen of 3 flowers is taken each time and mixed, stained at room temperature for 1 hour, and then examined under the microscope , was dyed deep red and considered to have vitality, counted 5 visual fields, and calculated the average value. The percentage of viability of pollen was expressed by staining rate.

Embodiment 2

[0055] A kind of capsicum breeding method, comprises the steps:

[0056] (1) A pepper variety with strong stress resistance (Jijiao 126) was selected as the female parent, and a pepper variety with high yield (Chifeng Niujiao pepper) was selected as the male parent;

[0057] (2) In the afternoon before flowering, the female parent (Jijiao 126 pepper) was artificially castrated, and the viability of the pollen during the flowering period and the pollination of the stigma were measured;

[0058] The pollen viability of artificially emasculated flowers is measured, stained with TTC solution, and samples are taken from the field every 3 hours starting from 8:00 in the morning, and the pollen of 3 flowers is taken each time and mixed, stained at room temperature for 1 hour, and then examined under the microscope , was dyed deep red and considered to have vitality, counted 5 visual fields, and calculated the average value. The percentage of viability of pollen was expressed by stai...

Abstract

The invention discloses a breeding method of pepper. According to the method, artificial pollination is performed after artificial emasculation of the pepper, a first-filial generation is obtained firstly and then three generations are back-crossed, and then the breeding of the pepper is quickened through a tissue culture technology; a drought-resistant strain is induced through stress treatment of polyethylene glycol. The obtained pepper new product has good stress resistance, can resist the diseases such as diseases, virus diseases and anthracnose of the pepper, is low-temperature-resistant, has high weak light capacity, and organically combines the advantages of different pepper resources. The method has the advantages of superior agronomic characters, good plant growth, increased plant height, difficulty in lodging and high yield.

Description

technical field [0001] The invention belongs to the field of plant breeding, and in particular relates to a pepper breeding method. Background technique [0002] In capsicum breeding, uniform yield is the ultimate goal pursued by breeders. However, with the expansion of planting areas, its adaptability is also a factor that needs to be considered. Breeders must breed peppers with good texture, good flavor, and high nutritional content to meet the needs of consumers. varieties. However, in the past, breeders did not pay enough attention to breeding to improve the nutritional value of peppers, and compared with the goals of disease resistance and high yield, there was a big gap. [0003] In recent years, the application of conventional breeding in pepper is not the main means. Because it often takes more than six or seven generations to breed a variety, the progress is slow, and the effect is not very satisfactory. With the rapid development of production, conventional bree...
