Example Embodiment
[0028] Example 1
[0029] Pepper variety: Yanjiao No. 1
[0030] A method for improving the efficiency and yield of pepper hybrid seed production, including the following steps:
[0031] (1) Adjusting the sowing period: seed production in a greenhouse in early spring facilities in Yancheng, Jiangsu Province, sowing on December 20, male parent sown 7 days earlier than female parent, and seedlings raised on a heated wire bed;
[0032] (2) Reasonable dense planting: On March 15th of the next year, plant in the facility greenhouse. The planting ratio of male and female parents is 1:4. The facility greenhouse is covered with nylon mesh with two arches, and the parents are planted in nylon mesh. Inside the yarn, the nets around the yarn are sealed to isolate the foreign pollen, and the seeds are isolated and propagated. The purity of the parents is 99.9%. According to the plant height and plant width of the male and female parents, determine the cultivation density of the father and the fem...

[0041] Pepper variety: Yanjiao No. 2
[0042] A method for improving the efficiency and yield of pepper hybrid seed production, including the following steps:
[0043] (1) Adjusting the sowing period: seed production in a greenhouse in early spring facilities in Yancheng, Jiangsu Province, and sowing on December 20, with male parents sown 10 days earlier than female parents, and seedlings raised on a heated wire bed;
[0044] (2) Reasonable dense planting: On March 10th of the following year, planting in the facility greenhouse, the planting ratio of male and female parents is 1:4, the facility greenhouse is covered with nylon mesh with two arches, and the parents are planted in nylon mesh. Inside the yarn, the net around the yarn is tightly sealed to isolate foreign pollen, and the parents are tested for purity of 99.9%. According to the plant height and plant width of the male parent and the female parent, determine the cultivation density of the parent and the fe...

Abstract
The invention provides a method for improving the hybrid seed production efficiency and increasing the yield of hot pepper. The method comprises the following steps: adjusting the sowing time, reasonably performing dense planting in a facility, adjusting plants, collecting pollen, emasculating and pollinating, performing plant management after pollination, harvesting seeds and the like. Through covering with nylon gauze in the facility for isolated breeding, the purities of parents are guaranteed to meet original seed requirements; through adjustment of the sowing time, the most suitable climatic condition is provided for flower synchronization of the male and female parents and the pollination; through reasonable dense planting in the facility, a suitable microclimate environment can be created for hot pepper seed production, and the planting density and the planting ratio of the male and female parents are determined according to the parental plant height and pollen collecting requirements; through improvement on a method for collecting pollen of the male parents, the pollen amount and the pollen quality are guaranteed; emasculation, pollination and labeling are completed in onetime, so that repeated pollination is not needed, the labor is reduced, and the seed production efficiency is improved; through plant management after the pollination, the seed setting rate is also improved; the problems that in the prior art, the efficiency is low, the yield is not high and the purity is unstable in the hybrid seed production process of the hot pepper are solved.
Description
technical field [0001] The invention provides a high-efficiency and high-yield capsicum hybrid seed production method, which belongs to the technical field of plant cultivation and breeding. Background technique [0002] Capsicum (Capsicum.annum L.) originates in Central and South America, belongs to Solanaceae Capsicum, is an important vegetable and condiment, and is also one of the vegetables with the largest planting area in China, with an annual planting area of 1,300,000hm 2 Above, second only to Chinese cabbage, occupying the second place, is the vegetable crop with the largest output value in China, and plays an important role in ensuring the annual supply of vegetables in China (Zou School. "Pepper Genetics and Breeding". Beijing: Science Press, 2009). [0003] Capsicum is a bisexual flower, and hermaphrodite. The heterosis of pepper is obvious, and the hybrid varieties have been widely used in production. Since the 1980s, my country has started the breeding of p...
