Paddy rice hybridizing method

Abstract

The present invention discloses a submerged rice hybridization method. It includes the steps of emasculation, pollination and returning into field. Said invention adopts CO2 gas to treat rice ear, and utilizes vacuum pump to such and remove pesticide, and makes them be organically combined together, so that it can raise technical content of submerged rice hybridization method, reduce its hybridization work difficulty and raise its working effect.

Description

Technical field:

[0001] The invention relates to a rice hybridization method. Background technique:

[0002] Rice hybridization is one of the indispensable and important ways to create a source of variation in rice breeding, and plays an important role in breeding. At present, the commonly used method is to adopt the operating procedure of "detasseling with warm soup on the female ear - clipping glumes and emasculation - bagging and isolation - clipping glumes on the male parent to promote flowering - cross-pollination". Among them, the detasseling technology in warm soup is relatively high, and if there is a slight negligence, either the detasseling effect will not be achieved, or the entire tassels will be killed. However, glume clipping and emasculation will take a lot of work and take a lot of time, which will affect the speed of hybridization and the number of combinations. , The pollination link is also relatively troublesome. If some rice breeding materials encounter...
