Characterization and variability analysis in pointed gourd (Thichosanthes dioica Roxb.)
Author(s): S. Islam and S. Datta
Abstract: To study the morphological characteristics and variability component of 31 genotypes of pointed gourd, an experiment was undertaken with randomized block design with three replications. Results revealed that there was a significant variation among the different genotypes for morphological as well as yield and quality characters. Highest range of deviation was found for average number of fruits per plant (56.15-219.75) followed by average fruit weight (19.12-38.04 g). Highest phenotypic coefficient of variation and genotypic coefficient of variation was observed for yield per plant (41.24 and 40.82, respectively) followed by fruits per plant (31.66 and 31.07, respectively). The high heritability was recorded for node number at which first female flower appears (99.33 %). High heritability along with high genetic advance as percentage of mean was found for different yield, quality and yield contributing attributes. However selection may be forwarded based on the yield per plant, fruits per plant and seeds per fruit.
