High-yield hybrid seed production method for tomatoes

Abstract

The invention discloses a high-yield hybrid seed production method for tomatoes, and relates to the technical field of hybrid seed production. According to the technical scheme adopted by the invention, the high-yield hybrid seed production method comprises the following steps: firstly, trimming maternal plants to remove all flowers in blossom on the plant, and simultaneously pruning to remove all branches and internal branches which are thin and weak, and hypoplastic under the first fruit; starting to select flower buds to be in blossom next day from the second layer to the fourth layer of flowers, and carrying out castration after 5 o'clock in that afternoon; in the morning a day before pollination or at 7 o'clock to 10 o'clock in that morning, collecting mature and non-crack anthers, and drying the collected mature and non-crack anthers in a dryer for later pollination use; staining a writing brush or an eraser head with pollen preferably from 7 o'clock to 10 o'clock in the morning in general, and lightly coating the pollen on flower stigmas subjected to castration; and harvesting the fully-matured fruits about 50-70 days after pollinating. According to the high-yield hybrid seed production method for tomatoes, the purity and the yield for tomato seed production and the plumpness of the seeds are improved.

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 tomato. Background technique [0002] The current tomato seed production mainly uses the method of detasseling and pollination at the same time in flower selection. If the pollen is produced, 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 sit on the fruit. Traditional tomato pollination methods have limited tomato seed production. Contents of the invention [0003] The purpose of the present invention is to provide a high-yield hybrid seed production method of tomato, which selects the flowers that will open the next day, the flowers are moderately selected, and the flower stigma grows and develops overnight, and the m...

[0002] The current tomato seed production mainly uses the method of detasseling and pollination at the same time in flower selection. If the pollination is already produced, 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 sit on the fruit.
