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 the technical field of hybrid seed production, in particular to a high-yield hybrid seed production method for sweet peppers. According to the technical scheme, the method includes the steps that a maternal plant is trimmed, all flowers, opening already, on the plant are picked off, pruning is carried out at the same time, and all branches below peppers grown out first and inner thin, weak and stunted branches are picked off; starting from flowers on the 2-4 layers, flower buds to open on the second day are selected and castrated after 5 pm in the afternoon of the same day; in the morning of the day before or at 7-10 am in the morning of the same day, matured and non-cracked anther is collected and dried in a dryer for pollination; generally at 7-10 am in the morning, and a writing brush or rubber head can be used for being stained with pollen and slightly coating the pollen onto castrated stigmas; about 50-70 days after pollination, fruit can be harvested when fully matured. Purity of sweet pepper seed production and seed plumpness are improved, and the yield is increased.
