Development of a multicriteria decision-making model for evaluating hybrid offspring in the sweetpotato (<i>Ipomoea batatas</i> L.) breeding process

Abstract

Sweetpotato variety breeding is always a long process. Screening of hybrid offspring is dominated by empirical judgment in this process. Data analysis and decision fatigue have been troubling breeders. In recent years, the low-efficiency screening mode has been unable to meet the requirements of sweetpotato germplasm innovation. Therefore, it is necessary to construct a high-efficiency method that can screen germplasms for different usages, for mining elite genotypes, and to create dedicated sweetpotato varieties. In this article, the multicriteria decision-making (MCDM) model was constructed based on six agronomic traits, including fresh root yield, vine length, vine diameter, branch number, root number and the spatial distribution of storage roots, and five quality traits, including dry matter content, marketable root yield, uniformity of roots, starch content and the edible quality score. Among these, the edible quality score was calculated by using fuzzy comprehensive evaluation to integrate the sensory scores of color, odor, sweetness, stickiness and fibrous taste. The MCDM model was compared with the traditional screening method via an evaluation in 25 sweetpotato materials. The interference of subjective factors on the evaluation results was significantly reduced. The MCDM model is more overall, more accurate and faster than the traditional screening method in the selection of elite sweetpotato materials. It could be programmed to serve the breeders in combination with the traditional screening method.

Evaluation of Aromatic Characteristics and Potential Applications of Hemerocallis L. Based on the Analytic Hierarchy Process

“…Among them, the most common one is principal component analysis (PCA), which serves as a multivariate tool to detect correlations between all the breeding lines and VOCs [ 13 ]. In addition, grey relational analysis [ 14 ] and fuzzy comprehensive evaluation [ 15 ] are also utilized to assess the overall quality of varieties based on their traits, aiming to select specific varieties. The analytic hierarchy process (AHP) is one of the most widely used multicriteria decision-making methods [ 16 ], as it can determine the most interesting types according to certain criteria.…”

A Multi-Criteria Decision-Making Model for Pontoon Bridge Selection: An Application of the DIBR II-NWBM-FF MAIRCA Approach

“…The application of MCDM methodologies across diverse sectors has been documented extensively in previous research, as elucidated in Table 1. [52][53][54][55][56] In this paper, the DIBR II-NWBM-FF MAIRCA MCDM model (Figure 1) is presented for the selection of the optimal set of pontoon bridge for the needs of the military.…”
