- Abstract
Spiny bitter gourd is a highly nutritious plant as its aril contains high contents of phytochemicals, especially - lycopene and beta carotene. The information on genetic variation in germplasm is important for development of new varieties. The objective of this study was to evaluate the genetic diversity of spiny bitter gourd based on agricultural traits and phytochemical contents. Twenty-six accessions of spiny bitter gourd collected from different parts of Thailand and Vietnam were evaluated in a randomized complete block design with 3 replications at the Fruit Orchard Research Farm, Department of Plant Science and Agricultural Resources, Faculty of Agriculture, Khon Kaen University, Thailand during July to October 2010. Genetic diversity of 26 accessions of spiny bitter gourd was identified based on horticultural traits (fruit fresh weight, aril weight, days to fruit maturity and number of seeds) and phytochemical contents (total carotenoids, lycopene, beta-carotene and lycopene per fruit). High variations were observed in these accessions for all agricultural traits and phytochemical contents. Cluster analysis showed that the 26 accessions of spiny bitter gourd could be grouped into 6 distinct clusters. The results are useful for germplasm conservation, utilization and management for breeding of spiny bitter gourd in the future.
