Cultivar evaluation and selection in Paeonia × suffruticosa Zhongyuan Group for specialized purpose to use
摘要
Abstract
Based on the investigation on morphological and ornamental characteristics of 196 cultivars in Paeonia × suffruticosa Zhongyuan Group,an analysis on the correlation degree with the standard cultivar (SC) by grey system theory was carried out to evaluate and select cultivars for three different specialized purposes,landscaping,potted-plant and cut-flower production.The results showed that,the cultivars had a correlation degree over 0.7 to SC can be selected to propagate for landscaping,and ones had a correlation degree over 0.8 to SC can be selected for potted-plants and cut-flower cultivation.According to the conclusion above,45 cultivars out of 196 investigated ones were recommended for production application,including 42 for landscaping,20 for potted-plants and 12 for cut-flowers.Among all the recommended ones,7 cultivars had the priority in production because they can meet all the requirements of landscaping,potted-plant and cut-flower production simultaneously.Fifteen cultivars were suited for landscaping as well as for potted-plant or cut-flower production.Three and 20 cultivars were only suited for potted-plant and landscaping respectively.Only a quarter of the total cultivars were selected,and the rest 151 were not well suited for mass production due to their unsatisfactory evaluation results.关键词
