Ultralow temperature preservation method for capsicum pollens

Abstract

The invention provides a preservation method for paternal pollens in the capsicum hybrid production. In the capsicum hybrid production, male parents and female parents are planted in a time staggering and allopatry mode, and the pollens of the male parents, which are concentratedly stored in liquid nitrogen, are transported to female parent planting sites for the usage during pollination. According to the invention, the flowering asynchronism of the male parents and the female parents in the capsicum hybrid production is thoroughly solved, so the simultaneous and sympatric appearance of capsicum at the seed production male parents and the seed production female parents is avoided, and the loss of the parent of the male parents can be effectively prevented; and superfluous pollens in the seed production can be stored, so the stored pollens can be used to cover the shortage when the amount of the pollens of the male parents is not enough.

Description

Technical field [0001] The invention relates to a method for preserving pepper pollen, which relates to commercial seed production of pepper, in particular to an ultra-low temperature preservation method for pepper pollen and its application in commercial seed production. Background technique [0002] During the seed production process of pepper hybrids, it often occurs that the parents do not meet at the flowering period, and the excessive pollen of the male parent causes unnecessary waste, and is easily affected by natural factors, which leads to the lack of pollen and affects the yield of seeds. The varieties carefully selected for many years are in the When producing seeds, the parents are planted together and are easy to be stolen. These problems have been plaguing breeders and seed companies all over the world. If the male parents are stored in the form of pollen for a long time and safely, they can be provided to the seed producers at any time, which can completely so...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome a series of problems such as parental flowering failure, excessive or lack of pollen, and easy loss of parents in the process of pepper hybrid seed production, the present invention provides a set of safe pepper flower preservation methods, and the preserved pollen can be used at any time , which can completely solve the problem of missing flowering in the production of pepper hybrids. The male parent can be planted in a more secluded place half a year in advance or earlier, so that the male parent of the new variety is not easy to lose, and the new variety can be protected.
