Pyrus ussuriensis, also known as the Ussurian pear, Harbin pear, and Manchurian pear, is a species of flowering plant in the family Rosaceae. It is native to Korea, Japan, and the Ussuri River area of far eastern Russia. It has flowers in spring that are slightly pink when budding and then turn white. Buds are dark brown and have an alternating arrangement. The tree grows to a height of about 15 meters (49 ft) and prefers well-drained loam-type soils. It is considered the hardiest of all pears. When planted in milder climates, the trees have been known to be killed by freezes after they begin budding. Many species of birds and mammals feed upon the fruit of this species. Deer, mice, and rabbits are known to damage the trees. Leaves are dark green in spring and summer and turn dark red and gold in autumn. Products made from the fruits may prove more effective than commercial insecticides in killing ticks and mites. The fruits are not the tastiest of pears to humans, but the taste is better after a freeze and the juice tastes better. Crosses of this species with other pears produces tasty pears that grow in climates too cold for most pears.

Intelligent system for correlation analysis of whole genome of pyrus ussuriensis on basis of deep learning
The invention discloses an intelligent autumn pear whole genome association analysis system based on deep learning, and relates to the technical field of gene deep learning, which comprises the following steps: collecting genotype data and phenotype data of autumn pears, obtaining a standardized data set through preprocessing, converting the standardized data set into a matrix form by adopting an image coding method, and carrying out correlation analysis on the whole genome of the autumn pears; extracting spatial features, and generating image data; analyzing the interaction among the multiple-effect gene identification data by adopting a graph convolutional network, obtaining gene interaction characteristics, identifying gene clusters participating in the same biological process, and generating a gene interaction network; and combining the gene interaction network with a deep convolutional neural network, analyzing the relationship between the genotype data and the phenotype data, obtaining deep feature data, identifying the gene locus of the pyrus ussuriensis, and generating a key gene locus analysis scheme. According to the method, the accuracy of genome correlation analysis is effectively improved, and important support is provided for gene research and accurate breeding of pyrus ussuriensis.

Method for establishing a high-efficiency regeneration system of autumn pear leaf
This invention discloses a method for establishing a high-efficiency regeneration system for *Pyrus pyrifolia* leaves, belonging to the field of plant tissue culture technology. The method includes: spreading a layer of sorbitol solution on the surface of a culture medium; inoculating *Pyrus pyrifolia* seedlings into the medium and placing them in a dark environment for etiolation treatment; taking etiolated leaves from the *Pyrus pyrifolia* seedlings and inoculating them in a regeneration medium for dark culture, then transferring them to light for further culture to produce adventitious buds; after the adventitious buds reach the target length, cutting off their lateral buds and placing them on a subculture medium to obtain regenerated seedlings. This invention, by adding sorbitol solution before dark treatment, can significantly shorten the time to obtain etiolated material to 7 days, and the etiolated plants are in better condition after three weeks; furthermore, by placing *Pyrus pyrifolia* tissue culture seedlings in a dark environment for dark culture, the physiological state of the tissue culture seedlings is altered, and the obtained etiolated leaves are inoculated into the regeneration medium, improving the regeneration efficiency, and the material acquisition is not affected by the season.
