Abstract:
To establish a comprehensive evaluation system of potted Curcuma alismatifolia varieties, and to provide a basis for screening the excellent varieties suitable for large-scale facility cultivation. The main quality characteristics of 20 Curcuma alismatifolia germplasm were observed and analyzed through pot experiment from 2019 to 2021. The comprehensive evaluation system of pot Curcuma alismatifolia germplasm was established from ornamental value, resource value and adaptability by using analytic hierarchy process and fuzzy analysis method. The index values of 18 evaluation factors were determined, among which the rarity of germplasm, flower viewing period, bract color, bract and leaf position were the most important, with weights of
0.1820,
0.1467,
0.1178 and
0.0893, respectively. According to the comprehensive evaluation score, the germplasm could be divided into four grades: excellent, good, average and poor, and the varieties with excellent grade could be recommended as pot varieties for industrial application. The comprehensive evaluation results were consistent with the actual production, which indicated that the evaluation system could screen and grade the varieties of potted Curcuma alismatifolia well. Six potted Curcuma alismatifolia varieties were screened out for industrial production, which provided reference for further development and utilization of Curcuma alismatifolia germplasm.
