Abstract

In this study, different characteristics of 38 Rosa damascena accessions were evaluated based on FLOWER YIELD, yield components and certain other traits. The experiment was conducted during 2006-2008 using a randomized complete block design with three replicates in Dezful, Iran. CORRELATION analysis showed significant relations between the traits. FLOWER YIELD correlated positively with flower number, flower fresh weight, flower dry weight and petal weight. Essential OIL CONTENT showed a significant positive CORRELATION with flowering duration but a negative CORRELATION with flower number. Also, the CORRELATION between plant canopy diameter and plant height was positively significant. Based on factor analysis results, for the first factor, flower dry matter percentage, flower fresh weight, flower dry weight, petal fresh weight and petal weight/flower weight were considered as the key selection factors and the most important traits. In the second factor, FLOWER YIELD, plant canopy diameter and OIL CONTENT had the most variation while, in the third factor, flower number and flowering duration had the highest values. In the fourth and fifth factors, plant height and petal number also showed the highest variation, respectively. Results of stepwise regression analysis showed a significant association between FLOWER YIELD and flower number, flower weight, flower dry matter percentage, plant canopy diameter, and a good fit was obtained for this association by linear regression model. According to the PATH ANALYSIS, the greatest direct positive effect on FLOWER YIELD was related to flower number and flower weight. Also, the effect of flower dry matter percentage shown on FLOWER YIELD was direct and positive. Plant canopy diameter via flower number showed a positive indirect effect on FLOWER YIELD. It could be concluded from this study that FLOWER YIELD and flower number are appropriate criteria for selecting superior Rosa damascena cultivars for Khuzistan and similar ecological conditions.
