Problems solved by technology

[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.
Traditional tomato pollination methods have limited tomato 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 tomato is a common cross-pollinated crop, and the possibility of pollen spreading by wind is small, tomato flowers are very attractive to insects, which can easily cause biological confusion and affect seed quality. Therefore, the isolation distance between tomato farming fields and other tomato varieties is required to be more than 500 meters.

[0016] 2. Sowing at the right time: The optimum temperature for tomato pollen germination 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 November, and the late-maturin...

Abstract

The invention relates to the technical field of hybrid seed production, in particular to a high-yield hybrid seed production method of tomatoes. The high-yield hybrid seed production method includes: finishing maternal plants to remove all flowers which bloom already on the plants, pruning branches, and removing all branches and inner weak shoots poorly developed below each first fruit; selecting buds which are about to bloom the next day starting from flowers on 2-4 layers, and performing emasculation after 5 P.M. on the very day; collecting mature anther which does not crack at the time from 7-10 A.M. of a previous day or the same day of pollination, and putting the anther into a dryer for drying for standby use during pollination; using a hairbrush or a rubber head to dip pollen to slightly coat emasculated stigma at the time of 7-10 A.M.; harvesting when fruit is fully mature 50-70 days after pollination. By the method, purity, yield and seed plumpness of tomato seed production 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...
