Rice variety comprehensive excellent index evaluation method

Abstract

The invention relates to the technical field of crop genetic breeding, particularly relates to a rice variety comprehensive excellent index evaluation method. An entropy weight and efficacy combined analysis method is adopted to screen and evaluate the variety excellence, and the problems of subjectivity, one-sidedness and reliability of a rice variety evaluation method are solved, and the difficulties in comprehensively and objectively analyzing and judging the variety as good, good taste and good processing to meet the requirements of yield, quality, stress resistance and other multi-dimensional characters are overcome. The implementation of the scheme mainly comprises the following steps: (1) establishing an evaluation system; (2) acquiring index data; (3) determining index weights; (4)calculating a comprehensive index; and (5) evaluating excellent varieties.

Description

technical field [0001] The invention relates to the technical field of crop genetics and breeding, in particular to a method for evaluating comprehensive good index of rice varieties. Background technique [0002] With the continuous and in-depth development of the rice industry, the output of the rice market exceeds the demand, and the demands of various economic entities such as rice planting, processing, and consumption on the maximization of market returns have been greatly enhanced, resulting in new and higher requirements for the excellent characteristics of varieties. In recent years, the number of rice variety approvals has increased year by year. How to select "good seed", "delicious" and "good processing" excellent varieties that meet the needs of various economic entities from a large number of approved varieties or emerging strains, and whether they are suitable as varieties It is a new research topic in the process of breeding parent utilization and large-scale ...

AI Technical Summary

Problems solved by technology

[0004] There are still few literatures on the application of rice variety comprehensive good index evaluation methods. Some literatures focus on the evaluation of rice variety tolerance to low fertilizer, low nitrogen tolerance, cold tolerance, quality traits, yield traits, etc., ignoring the multi-dimensional comprehensiveness of variety traits There is a possibility of over-evaluation or errors. Some literatures use analysis methods such as principal components, clustering, weight projection model, quaternary connection number multi-factor situation ranking, fuzzy comprehensive evaluation, DTOPSIS and gray correlation to evaluate rice varieties. , but there are problems of one-sidedness and instability of a single evaluation method and the effectiveness of combined evaluation methods, which affect the accuracy of evaluation results and make it difficult to ensure the efficient exploration and utilization of excellent varieties
