Efficient hybrid pollination method for pear trees

Abstract

The invention relates to an efficient hybrid pollination method for pear trees, and belongs to the field of plant hybrid pollination. The efficient hybrid pollination method for pear trees comprises the following steps: step 1, trimming a female parent tree; 2, a frame is erected after female parent trees are trimmed; 3, a shed cover is laid on the frame; 4, an observation window is formed in the shed cover; step 5, building a sunscreen net bracket, and laying a sunscreen net; step 6, collecting male parent pollen; 7, pollinating when flowers of the female parent trees bloom; 8, the frame and the shed cover are dismantled; step 9, taking out seeds of the fruits after the fruits are ripe; according to the efficient hybrid pollination method for the pear trees, insect pollination and pollen spreading along with wind can be efficiently blocked, natural pollination is effectively isolated, and meanwhile the problem that bagging is not needed after hybrid pollination is solved.

Description

technical field [0001] The invention belongs to the field of hybrid pollination of plants, and in particular relates to a method for efficient hybrid pollination of pear trees. Background technique [0002] According to specific breeding objectives, parents are selected and hybrids are obtained through hybridization, so that hybrid offspring are selected to breed new varieties that meet production and consumption requirements, which is called hybrid breeding. Cross-breeding is a breeding method that has been applied at home and abroad and is very effective. Regardless of the past, present or future, hybrid breeding is the most important way of fruit tree breeding. [0003] Pear tree is a kind of common fruit tree, its fruit is juicy and nutritious, and it is one of the fruits that people like in autumn and winter. Pears are highly self-incompatible and are generally not emasculated when crossed. The flowering period of pear trees is relatively concentrated and short, gene...

[0005] Chinese Patent Application Publication No. CN108668886A provides a non-selfing fruit tree hybrid pollination method, which belongs to the field of fruit tree hybridization technology, comprising the following steps: covering the female tree of the same species with an insect-proof device in the early flowering stage; Place the wall honeycomb in the wall honeycomb, and place the male parent target pollen in the wall honeycomb; place the wall honeycomb cocoon in the wall honeycomb, so that the wall honeycomb that hatches from the cocoon carries the target pollen to pollinate the female parent tree; Recover wasp eggs; the insect-proof net used in this patent generally has large holes, which cannot prevent pollen from spreading with the wind. When the holes of the insect-proof net are small, the wasp placed inside cannot survive for a long time. conditions, resulting in too much space in the final covered area
