Method for measuring and analyzing phenotypic fruit point data of pear germplasm resources

Abstract

The invention provides a method for measuring and analyzing phenotypic fruit point data of pear germplasm resources, which comprises the following steps of: acquiring a pear surface image, preprocessing the image to remove noise in the image, counting the fruit point data in the image, and analyzing the data to obtain the fruit point density. According to the invention, pear germplasm resource fruit point data is measured based on machine vision, the statistical efficiency of fruit point data in pear germplasm research is greatly improved; statistical data types are increased, manual detectionis replaced by a machine, the cost can be reduced, statistical errors caused by manual measurement errors can be reduced, the number, the size and other information of pear surface fruit points can be counted, the fruit point density can be calculated, and the method has far-reaching significance in pear germplasm research.

Description

technical field [0001] The invention belongs to the technical field of pear germplasm resources, in particular to a method for measuring and analyzing phenotypic fruit point data of pear germplasm resources. Background technique [0002] Pear is the third largest fruit in my country, with an existing planting area of ​​about 1,040,600 hectares and an annual output of about 15,231,900 tons, accounting for 68.2% of the world's total pear tree harvest area and 67.3% of the world's total pear tree output. my country is the world's largest pear resource production and consumption countries. [0003] Phenotypic diversity mainly studies the phenotypic variation of populations in various environments in their distribution area, which is an important research content of biodiversity. Research and analysis of phenotypic diversity of pear germplasm resources is helpful to understand the traits of pear germplasm resources The genetic development mechanism is conducive to the evaluation ...
