Problems solved by technology

[0003] The powder shake method is greatly affected by the weather, the effect is poor in cloudy days, and it cannot be carried out in rainy days; it is greatly affected by the flowering period, and it can be used when the pollen is sufficient in the full flowering period; due to the short flowering period of wheat, this method limits the number of hybrids
It causes waste to detasselled parchment paper bags, which cannot be reused after being cut and destroyed

Embodiment 1

[0038] The present embodiment provides the hybrid pollination method of wheat, and this pollination method comprises the following steps:

[0039] 1.1 Take a centrifuge tube with a volume of 40mL and fill it with water;

[0040] 1.2 Fix the centrifuge tube filled with water to one end of a fixed pole with a height of 100cm by using a rubber band;

[0041] 1.3 Insert the end of the centrifuge tube fixed on the fixed pole to the side of the wheat parent material (within 2-5cm next to the wheat parent);

[0042] 1.4 Detassell the female ear of the female parent material, fold the two corners of the suture end of the paper bag and fix it with a pin, and use the paper bag to cover the ear of the female parent;

[0043] 1.5 Take 2 wheat male parent materials (cut off from the bottom of the male stalk as much as possible), and remove the wheat awn to obtain the male parent material;

[0044] 1.6 Place the clipped parent material in a centrifuge tube;

[0045] 1.7 Adjust the height...

Abstract

The invention belongs to the technical fields of biology and genetic breeding, and provides a cross pollination method for wheat. The method is characterized in that paternal plants are obtained through cutting, awns are removed from the paternal plants, the paternal plants are placed in a water-filled centrifugal tube and bound with a maternal plant, and a maternal ear and paternal ears are covered in a same kraft paper bag; and when the paternal plants bloom, the paper bag is gently patted to complete pollination. The method has the advantages that weather effects can be effectively avoidedthrough the bagging method; and the wheat pollination rate is improved.

Description

technical field [0001] The invention relates to the technical field of biology and genetic breeding, in particular to a cross-pollination method for wheat. Background technique [0002] At present, most of the wheat hybridization methods in the agricultural field are powder-shaking methods; that is, take 2-3 ears of male parent material, cut off the awns and place them in a windless / sheltered and sunny environment. After the glumes open, cut them and put them on the female parent. Open the top of the parchment bag, put the male ear upside down in the cut parchment bag, twist the stalk repeatedly with your fingers, so that the male powder falls on the stigma of the female parent, after the shaking is completed, Take out the male ear, fold the cut top and seal it with a paper clip or pin, and the pollination is complete. [0003] The powder shaking method is greatly affected by the weather, the effect is poor in cloudy days, and it cannot be carried out in rainy days; it is g...
