Embodiment 1

[0023] Embodiment 1, a kind of hybridization method of wheat

[0024] 1. Hybrid bag

[0025] 1. Hybrid bag

[0026] The hybridization bag of the present invention is to be raw material with kraft paper, and the inside of the kraft paper bag made of kraft paper is black, and the outside is yellow, and the specification is: 18cm*8cm (length*width). The top port is sealed and the bottom port is open.

[0027] 2. How to use the hybridization bag

[0028] In the process of wheat hybridization, after clipping glumes and emasculation, put on the kraft paper bag described in step 1, fold the lower opening in half, fix it, and nail it firmly with a stapler; when pollinating, cut the upper opening, Carry out pollination, after finishing, the mouth is folded lightly, nails firmly with stapler.

[0029] 2. Hybridization

[0030] Use Jimai 22 as the female parent, carry out the whole ear, use the kraft paper bag and the white sulfuric acid paper bag described in step 1, respectively, ...

Abstract

The invention discloses a wheat hybridization bag and application thereof. The hybridization bag disclosed by the invention is a kraft paper bag prepared from kraft paper; the kraft paper has double layers, and the colour of at least one layer of the kraft paper in the double layers is lightproof; the kraft paper bag is provided with two openings, one opening of the kraft paper bag is sealed, and the other opening of the kraft paper bag is open. Experiments prove that seeds obtained after carrying out bagging treatment by using the kraft paper bag disclosed by the invention are remarkably improved in the aspects of sizes and vitality indexes; moreover, the hybridization bag disclosed by the invention is low in cost, and great in popularization and application values in a wheat hybridization technology and even other plant hybridizations.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a wheat hybrid bag and its application. Background technique [0002] Wheat is a conventional species. In the process of cultivating new varieties, the hybridization technology has to go through multiple processes such as ear selection, ear whole, emasculation, bagging, and pollination. However, at present, wheat hybridization techniques are mostly carried out by heavy clipping, emasculation, and ear-twisting pollination methods, but after pollination, white sulfuric acid paper bags or more transparent cellophane bags are often used. After using clipped glume and heavy clipped glume, the obtained hybrid grains were obviously smaller and less plump, and the heavier the clipped glume, the smaller and shrunken the grain. In turn, the grain vigor of the F1 generation decreased, and the group vigor performance was poor, which led to deviations in the selection of offspring. ...
