Wheat breeding hybridization pollinator

Abstract

The invention discloses a wheat breeding hybridization pollinator which comprises a first ventilation pipe, a pollen container and an air bag, wherein the pollen container is arranged at the top of the first ventilation pipe in a communicating mode, the tail of the first ventilation pipe is connected with the air bag, and a second ventilation pipe sliding in the length direction of the first ventilation pipe is arranged in the first ventilation pipe, a plurality of pollen outlets are evenly formed in the bottom pipe wall of the second ventilation pipe at intervals, an unfolding mechanism is arranged on the outer wall of the first ventilation pipe, a connecting rod is arranged on the unfolding mechanism, and a pollen brush is arranged at the movable end of the connecting rod. The wheat breeding hybridization pollinator can solve the technical problem that the pollination of an existing pollinator is not uniform enough.

Description

technical field [0001] The invention belongs to the technical field of hybrid seed production of crops, and in particular relates to a hybrid pollinator for wheat breeding. Background technique [0002] Wheat breeding has been carried out in our country for decades, and many excellent varieties have been selected and bred through the hard work of wheat breeders. With the continuous changes of climate, physiological races of pathogenic bacteria and consumer requirements, wheat breeders must continue to Only by working hard can we breed new wheat varieties that are disease-resistant, high-quality, high-yield, widely applicable, and favored by consumers. The first step in wheat breeding is the combination of parents, that is, cross-pollination. The traditional method is to extend the pollen-scattered paternal tassels from the upper end into the emasculated hybrid bag and turn them back and forth, so that the pollen of the paternal parents can be freely scattered to the ground. ...

Problems solved by technology

The first step in wheat breeding is the combination of parents, that is, cross-pollination. The traditional method is to extend the pollen-scattered paternal tassels from the upper end into the emasculated hybrid bag and turn them back and forth, so that the pollen of the paternal parents can be freely scattered to the ground. On the stigma of the female parent, this method has a low seed setting rate, which limits the space for breeders to select excellent offspring

[0003] The utility model patent of the patent application publication number CN 205124621 U discloses a wheat hybrid pollinator, which includes a nozzle, an air flow hose, a pollen container and an air bag, and the pollen in the pollen container can be sprayed onto the wheat stigma through the nozzle by squeezing the air bag Pollination has technical effects such as good pollination effect and pollen saving, but because the pollinator sprays pollen through the nozzle, there is a situation of uneven pollen spraying, which affects the pollination effect, and then affects the wheat seed setting rate. Therefore, it is necessary to Design a hybrid pollinator for wheat breeding that can realize uniform pollination, improve pollination effect and wheat seed setting rate
