Description

Tomato breeding is with small-size pollen preservation pipe

Technical Field

The utility model belongs to the technical field of tomato breeding, and particularly relates to a small pollen storage tube for tomato breeding.

Background

The tomato cross breeding is a technology for obtaining first-generation excellent hybrid seeds by utilizing male parents and female parents with different excellent characters to carry out cross pollination, namely pollen is obtained from male parent plants in advance, and the pollen is temporarily stored and then is pollinated and hybridized on female parent plants. The storage condition of the pollen is preferably low temperature and dry, and the pollen can keep activity for 2-3 days under the condition of normal temperature. In the actual crossbreeding process, most pollen is stored in a large-capacity glass tube, and the method is suitable for large-scale field seed production. In the early stage of tomato breeding, breeding personnel need to perform cross pollination and hybridization on hundreds of male parents and female parents, so that the production efficiency is greatly reduced and the labor time is consumed if a seed production mode is adopted for pollination, and the correctness of pollen numbering cannot be ensured under the condition of numerous numbers. The existing common preservation tube has poor sealing performance and inconvenient later use of pollen.
