Title: Genetic variability and field performance of some sweet gourd (Cucurbita moschata Duch) accessions
Abstract: The experiment was conducted at the field and laboratory of “Collection, Evaluation, Conservation and Utilization of Landraces and Wild relatives of Some Important Vegetables and Fruits in Bangladesh (CVFB)” project, Department of Horticulture, Bangladesh Agricultural University, Mymensingh. Studies on field performance and genetic variability of sweet gourd accessions were carried out using morphological traits. Analysis of variance for different characters showed high degree of variation among the 43 accessions. The accession CM152 showed the best performance in respect of yield per plant (57.8 kg). The highest average fruit weight (10.43 kg) was recorded in CM154. Regarding the number of fruits per plant, CM145 produced the maximum number of fruits per plant (10.0). In all the traits genotypic coefficient of variation was smaller than phenotypic coefficient of variation. High heritability with genotypic and phenotypic coefficient of variation was observed for vine length at final harvest, number of male flowers per plant, node for first male flowers, average fruit weight, fruit cavity length and breadth, dry weight of 100 g flesh and number of seeds per fruit indicating additive gene effects of these traits.
Key Words: Genotypes, Genetic divergence and Sweet gourd
