An Early Identification Method of Excellent Maize Varieties

Abstract

The invention provides an early identification method for excellent maize varieties. The method comprises the following steps of: S1, obtaining a classification standard and classification indexes according to variety data of excellent maize varieties; S2, obtaining diffusion models of the excellent maize varieties according to the classification standard and the classification indexes; S3, obtaining key classification indexes of the excellent maize varieties on the basis of the diffusion models of the excellent maize varieties; and S4, identifying the excellent maize varieties on the basis ofthe key classification indexes so as to obtain identification results, and classifying the identification results on the basis of the classification standard so as to obtain a classification result.According to the early identification method for excellent maize varieties, the diffusion models and key classification indexes of the excellent maize varieties are explored from different spatial scales, so that the problem that the time and spatial differences in the diffusion processes of different traditional maize varieties cannot be sufficiently considered as the traditional maize varietiesare different in the aspect of suitability.

Description

technical field [0001] The invention relates to the technical field of planting information technology, and more specifically, relates to an early identification method for excellent corn varieties. Background technique [0002] The core competitiveness of the seed industry is the cultivation and search of excellent varieties. Since the final performance of varieties is affected by genes, environment, and gene-environment interaction effects, among them, excellent varieties can be divided into two categories: large-scale promotion areas nationwide for a long time, promotion in most provinces, and large-scale varieties with universal suitability. Varieties: regionally characteristic varieties with special suitability that have been promoted in a large area at the provincial level for a long time, and are only promoted in a limited number of provinces. [0003] Variety promotion has time and space attributes. Existing research methods still lack the exploration of the diffus...

AI Technical Summary

Problems solved by technology

[0004] However, the existing excellent variety identification methods do not fully consider the field performance of excellent varieties in actual promotion. Some of the varieties that have passed the provincial examination have not passed the national examination and been promoted, and most of the varieties that have passed the national examination and performed well have not achieved large scale. Area, long-term promotion, outstanding varieties have obvious cognitive problems
