Establishing comprehensive evaluation system for potted Oriental lily cultivars based on analytic hierarchy process

ObjectiveA comprehensive evaluation system for potted Oriental lily cultivars was established to screen the proper cultivars for scale planting in Guangxi.MethodTwenty botanical characters for twelve potted oriental lily cultivars were observed and recorded. A comprehensive evaluation system for potted Oriental lily cultivars was established using analytic hierarchy process from three perspectives of floral traits , leaf traits and growth adaptability. ResultThrough weight determing for floral traits,leaf traits and growth adaptability weights of 20 traits factors was calculated. Among all the factors, the weights of leaf burn (0.1429),flower formation rate (0.1372),flower diameter (0.1139),leaf abscission (0.0714) and plant type compact degree(0.0677) were high compared to others. According to the scores of comprehensive evaluation,twelve cultivars were divided into four grades:excellent,good,general,and poor. Five cultivars (Entertainer, Starlight express, Souvenir, Bahamas and Pink champion) with superior comprehensive traits could be applied to small scale planting. Fortune and After eight which were with poor comprehensive traits were eliminated. ConclusionEntertainer, Starlight express, Souvenir, Bahamas and Pink champion, which enjoy good traits of large flower, bright color, long florescence, compact plant type and strong adaptability, are suitable for introduction as potted lily cultivars in Guangxi.
