Fuzzy comprehensive evaluation for selecting mini watermelon cultivars.
BACKGROUND
The traditional method for selecting suitable mini watermelon cultivars has been shown to be flawed. The aim of the present study was to assess 11 mini watermelon cultivars using a new method, two-level fuzzy comprehensive evaluation (FCE). Three different characteristics for selecting the best cultivars were chosen to establish the evaluation index system, namely commercial trait, early maturity and high yield quality. Fifteen specific factors were used to reflect these three characteristics.


RESULTS
According to the final results of FCE, Linglongwang was selected as the best of the 11 cultivars overall. Autocopulation F1 of Hai 024 x Hai 011 was ranked second overall, while Heimeiren x Yun 05-2-1-1 was ranked lowest overall. Hai 051 x Hai 011 was the best cultivar in early maturity but worse in commercial trait and high yield quality than some other cultivars.


CONCLUSIONS
FCE can reflect the multiple characteristics of a cultivar objectively and precisely. This method has huge potential in selecting mini watermelon cultivars.
