Abstract
The invention discloses a rice hybridizing and detasseling method and belongs to the technical field of rice breeding.The method comprises the following steps: a, selecting single ears of rice to be hybridized; b, pruning the single ears of rice, keeping those that will bloom on the same day, cutting off surplus leaves, and cutting to break pollen sacs; c, soaking the cut single ears of rice in clear water for 4-6 min; d, taking out the soaked single ears of rice, and slightly flipping the single ears of rice with fingers so that pollen and the pollen sacs are flipped out; e, bagging the single ears of rice with the pollen ad pollen sacs flipped out so as to wait for pollination.The method has good detasseling effect, the purity of hybrids is up to 99.99%, fake hybrids are effectively decreased, and work efficiency is improved.
Description
Technical field
The present invention relates to a kind of method of paddy rice cross breeding emasculation stamen, belong to paddy rice breeding technology field.
Background technology
Breeding of hybridized rice needs two rice varieties to carry out sexual hybridization, a rice varieties as female parent is removed stamen, it pollinated with another rice varieties during hybridization. General emasculating method is a lot, such as water spray method, spray vinegar method, cuts Ying's method etc. But in currently available technology, emasculation effect is poor, and hybrid purity is low.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of method of paddy rice cross breeding emasculation stamen, and its emasculation effect is very good, and the purity of hybrid can reach 99.99%, effectively reduces pseudo-hybrid strain, it is to increase working efficiency.
Technical problem to be solved by this invention takes following technical scheme to realize:
A method for paddy rice cross breeding emasculation stamen, it comprises the following steps:
The single fringe of the paddy rice hybridized is done in a, selection;
B, the single fringe of pruning paddy rice, stay the spike of rice that can bloom the same day, cut unnecessary blade, and break pollen sac;
C, by single for the paddy rice after shearing fringe, it is placed in clear water and soaks 4-6 minute;
D, single fringe of taking out soaked paddy rice, with finger flick the single fringe of paddy rice several under, namely pollen and pollen sac are ejected;
E, the single fringe bagging of paddy rice that will eject pollen and pollen sac, wait pollination.
The single fringe of paddy rice after shearing in described step c, is placed in clear water and soaks 5 minutes.
The invention has the beneficial effects as follows: emasculation effect of the present invention is very good, and the purity of hybrid can reach 99.99%, effectively reduce pseudo-hybrid strain, it is to increase working efficiency.
Embodiment
In order to the technique means to the present invention, creation characteristic, reach object and effect is easy to understand, below in conjunction with specific embodiment, set forth the present invention further.
Embodiment 1
A method for paddy rice cross breeding emasculation stamen, it comprises the following steps:
The single fringe of the paddy rice hybridized is done in a, selection;
B, the single fringe of pruning paddy rice, stay the spike of rice that can bloom the same day, cut unnecessary blade, and break pollen sac;
C, by single for the paddy rice after shearing fringe, it is placed in clear water and soaks 4-6 minute;
D, single fringe of taking out soaked paddy rice, with finger flick the single fringe of paddy rice several under, namely pollen and pollen sac are ejected;
E, the single fringe bagging of paddy rice that will eject pollen and pollen sac, wait pollination.
As preferential scheme, the single fringe of the paddy rice after shearing in described step c, is placed in clear water and soaks 5 minutes.
Emasculation effect of the present invention is very good, and the purity of hybrid can reach 99.99%, effectively reduces pseudo-hybrid strain, it is to increase working efficiency.
More than show and describe the ultimate principle of the present invention and the advantage of main characteristic sum the present invention. The technician of the industry is not it should be understood that the present invention is restricted to the described embodiments, and without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention. The claimed scope of the present invention is defined by appending claims and equivalent thereof.
