Sweet potato germplasm resource evaluation method based on multi-criterion decision

Abstract

The invention relates to a sweet potato germplasm resource evaluation method based on multi-criterion decision, which comprises the following steps: screening sweet potato agronomic and quality related traits through a literature method, a research method, an expert consultation method and the like, and determining core traits, namely evaluation indexes; calculating a weight value of the evaluation index through a comprehensive weighting method in combination with a subjective weighting method and an objective weighting method; and finally, calculating evaluation index data through multi-criterion decision analysis to obtain scores and rankings of the evaluated germplasm. The invention has the advantages that the method is high in reliability, deep in mathematical background and suitable for comprehensive analysis and processing of large-batch sample data, the value potential of sweet potato germplasm in different purposes can be analyzed at the same time, the situation that sweet potato breeding workers neglect and omit some excellent genotypes due to decision fatigue can be avoided, and the germplasm evaluation efficiency is greatly improved. By adopting the method disclosed by the invention, excellent germplasm screening, cross parent selection, filial generation screening and the like of the sweet potatoes can be effectively guided, and a scientific and efficient evaluation model is provided for creation of special sweet potato varieties.

Description

technical field [0001] The invention relates to the field of sweet potato breeding, in particular to a method for evaluating sweet potato germplasm resources based on multi-criteria decision-making. Background technique [0002] Sweet potato (Ipomoea batatas (L.) Lam.), also known as sweet potato, sweet potato, sweet potato or sweet potato, belongs to Convolvulaceae (Convolvulaceae). The world's seventh largest food crop of maize, potato, barley and cassava. Because of its high yield, wide adaptability and strong stress resistance, sweet potato once became an important food crop for "overcoming famine and disaster relief" in poverty-stricken areas. At the same time, sweet potatoes are also very nutritious, and the potato pieces are rich in starch, soluble sugar, dietary fiber, protein, fat, vitamins and minerals. In addition, sweet potatoes also contain functional ingredients such as polysaccharides, polyphenols, polyterpenes and glycoproteins that are beneficial to the hu...

Problems solved by technology

In summary, although mathematical methods have been introduced and applied in the evaluation of sweet potato germplasm resources, the process of index selection and weight assignment has not been studied in depth, and the model for simultaneous evaluation of sweet potato multi-purpose applications has not yet been reported.
