However, when pollinating those pear varieties with unknown S genotypes, it is often not known which varieties should be used as pollinating trees to ensure production. There will be a certain degree of blindness and luck when pollinating. In production practice, there are some p

Embodiment 1

[0027] (1) Preparation of pollen

[0028] The pollen collection method of ‘Jinzhui pear’: pick the big bell flower of ‘Jinzhui pear’ which is ready to bloom, bring it back indoors, rub the flowers to separate the anthers from the filaments, and sieve the anthers with a fine mesh sieve. When picking flowers after rain or when the petals are stained with dew, they should be dried before rubbing the flowers. The anthers are spread evenly in a single layer in a room with a temperature of 20-25°C, a relative humidity of 70%-80%, and no direct sunlight, and the pollen can be shed after 1-2 days. The exploded pollen is wrapped in small packets with paraffin paper, placed in a color-changing silicone box, and wrapped with tin foil to achieve the purpose of drying and shading. If it is convenient for off-site demand or long-term storage of 'Jinzhui pear' pollen, it needs to be refrigerated in liquid nitrogen for storage and transportation.

Abstract

The invention belongs to the field of plant pollination biology and discloses a method for promoting complete affinity of intervarietal pear pollination. The method utilizes pollen of ''jinzhuili'' as a universal pollen to carry out artificial pollination on other pear varieties. As deprivation of a specific recognition function of a stamen of the ''jinzhuili', the pollen shows hybridization affinity when it is pollinated with any other pear variety with an S gene type. The technology solves a problem of selection of appropriate pollen for pear artificial pollination and changes complex pear pollen supply situation; long-term storage of the ''jinzhuili' pollen germ plasm can well solve a problem of flowering asynchronism during a pear breeding process or a problem of pollen supply during an allopatry pollination process; besides, the technology can be applied to industrialized production and has wide pollen germ plasm supply market and good economic benefit.

Description

technical field [0001] The invention belongs to the field of plant pollination biology and relates to a method for promoting complete compatibility of pollination among pear varieties. Background technique [0002] Pear is one of the main fruits in my country and even in the world. my country's existing cultivated area is 1,258,400 hectares, and it is the third largest fruit in my country. Pears are gametophytic self-incompatibility fruit trees, and most varieties are self-pollinating and do not bear fruit. Pollination trees must be deployed in production to obtain the expected yield and quality. However, when using artificial pollination, it should be avoided that the pollen used is the same as the S genotype of the pollinated tree, otherwise fertilization cannot be completed, fruit setting will not be possible, and the yield will be seriously affected, or even harvested. This just makes us have certain trade-offs to the selection of the pollination tree of pear variety, c...
