High-yield hybrid seed production method for sweet peppers

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.

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.
