Rice hybridization and castration method

Abstract

The invention provides a rice hybridization and castration method, belongs to the technical field of crop breeding, and particularly relates to a novel rice hybridization and emasculation-water spraying-castration method. The rice hybridization and castration method comprises the following steps: 1, selection of a reasonable sowing date; 2, selection of rice plants; 3, pruning of rice ears; 4, emasculation, water spraying and castration; 5, timely and efficient pollination. Through the adoption of the rice hybridization and castration method, the problem that the conventional rice hybridization work fails due to high labor intensity, incomplete castration and damage to pistil is solved; the rice hybridization and castration method has the advantages that the labor consumption and the cost are reduced, the operation is simple and convenient, the hybridization success rate is high, and the economical and environment-friendly effect is achieved, is deeply welcomed by scientific research breeding workers, and has a broad application prospect.

Description

technical field

[0001] The invention relates to a rice hybrid detasseling method, which belongs to the technical field of crop breeding, and specifically relates to a new method of rice hybrid clipping and water spraying detasseling. Background technique

[0002] Rice hybridization is an indispensable and important way to improve the traits of rice varieties and create sources of variation in rice breeding. The existing rice hybridization methods have their own advantages and disadvantages: 1. The method of manually cutting glumes and emasculation is more labor-intensive, and the damage to the glumes is relatively large, and if you are not careful, it will damage the flower organ and reduce the seed setting rate; 2. Warm soup to kill males This method can avoid self-fertilization, and the seed setting rate is higher, but it is required to master the suitable temperature and time required for killing males of different rice varieties. Also accomplish both that stamen...
