Problems solved by technology

[0002] The current sweet pepper seed production mainly uses the method of emasculation and pollination at the same time. This method is widely used, mainly because it is convenient to save time, but it has obvious defects, mainly reflected in the difficulty in flower selection. If it is too large, the pollination will be produced, and the purity of seed production will be reduced. If the selected flowers are too small, the growth of the flower room will not be good, especially the stigma, the pollination and fertilization effect will be poor, and it will be difficult to set the fruit. Even if the fruit is set, the number of seeds is often small and the yield is very low
Traditional sweet pepper pollination methods have limited sweet pepper seed production

Embodiment Construction

[0014] The present invention is mainly aimed at the flower selection and pollination link, and the detailed process of main hybrid seed production is as follows:

[0015] 1. Strict isolation: Although sweet peppers are often cross-pollinated crops, and the possibility of pollen spreading by wind is small, sweet pepper flowers are very attractive to insects, which can easily cause biological confusion and affect seed quality. Therefore, the isolation distance between sweet pepper farming fields and other sweet pepper varieties is required to be more than 500 meters.

[0016] 2. Sowing at the right time: The optimum temperature for the germination of sweet pepper pollen is 20-25°C, so seedlings of the right age should be cultivated by adjusting the sowing time and controlling the temperature. In order to make the parents reach the full flowering stage at the right time for hybridization, seedlings can be raised in cold beds. The early and mid-maturing varieties are sown in early...

Abstract

The invention provides a high-yield hybrid seed production method for pimento and relates to the technical field of hybrid seed production. According to the technical scheme, the method comprises the following steps of: settling the maternal plant, removing all the blooming flowers on the plant and meanwhile pruning, removing all the branches under pimento and internal weak hypogenetic branches; selecting the flower buds which will bloom in the next day from 2-4 layer flowers and performing castration after 5 p.m. on the same day; gathering mature non-dehiscent anthers in a dryer for drying at 7 a.m. to 10 a.m. in the previous day or same day of pollination, standing by for pollination; generally, at 7 a.m. to 10 a.m., using a writing brush or eraser head for taking pollen and slightly coating on the stigma of castration; and harvesting when the fruit is fully mature after being pollinated for about 50-70 days. According to the method provided by the invention, the purity of the pimento seed, yield and seed plumpness are increased.

Description

technical field [0001] The invention relates to the technical field of hybrid seed production, in particular to a method for high-yield hybrid seed production of sweet peppers. Background technique [0002] The current sweet pepper seed production mainly uses the method of emasculation and pollination at the same time. This method is widely used, mainly because it is convenient to save time, but it has obvious defects, mainly reflected in the difficulty in flower selection. If it is too large, the pollen will be produced, the purity of seed production will be reduced, if the selected flowers are too small, the flower room will not develop well, especially the stigma, the pollination and fertilization effect will be poor, and it will be difficult to set the fruit. Even if the fruit is set, the number of seeds is often small and the yield is very low. Traditional sweet pepper pollination methods have limited sweet pepper seed production.
