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 relates to a high-yield hybrid seed production method for sweet pepper, and relates to the technical field of hybrid seed production. A technical solution comprises the steps of firstly finishing maternal plants; removing all blossomed flowers from the plants; pruning to removal all branches below door pepper and branches that are weak and hypogenetic; selecting flower buds to be blossomed in the next day from a second layer flower to a forth layer flower; emasculating after 5 o'clock in the afternoon; harvesting mature but non-cracked anther in the morning a day before fertilization or at 7-10 o'clock in the morning; drying the harvested anther in a drier for use in fertilization; dipping pollen with a writing brush or eraser head at 7-10 o'clock in the morning; coating emasculated stigma with the pollen; and harvesting in 50-70 days after the fertilization when the fruits are fully mature. The method increases purity, yield and seed plumpness for the seed production of the sweet pepper.

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.
