“…Highest average inter-nodal length (13.15 cm), beta carotene content (154.36 μg/100g of fresh fruit) and second highest ascorbic acid content (19.33 mg/100 g of fresh fruit) were recorded in Cluster VIII. Similar trends were also explained by Debata et al (2017) in pointed gourd. The contribution of each trait to total divergence is presented in Table 4.…”

“…There appears to be more genetic variation among the genotypes between clusters as the average inter-cluster distances were greater than the average intra-cluster distances. The presence of genetic variation among the genotypes and their independent identity was inferred by larger intercluster distances than intra-cluster distances (Debata et al 2017). There was a remarkable deviation in the mean performance of eight clusters with respect to different attributes (Table 4).…”

Thirty one indigenous pointed gourd genotypes were studied in Terai region of West Bengal, India to observe variation of fruit morphology and genetic divergence using Mahalanobis D2 statistics and principal component analysis. The field experiment was designed in RBD with three replications at Uttar Banga Krishi Viswavidyalaya, West Bengal, India during the year 2018-19and 2019-20. All the genotypes were arranged into eight divergent clusters in which cluster I included maximum number followed by cluster II. The highest contribution towards genetic diversity was shown for node at the first female flower (37.85%) followed bychlorophyll a content of leaf (16.77%) and seeds per fruit (12.04%). Principal component-1 had maximum variability (43.83%) with positive loading for the characters like node at the first female flower (0.298), appearance of first female flower (0.265), days to fruit maturity (0.194) and internodal length (0.137). Based on the inter and intra cluster distance cross combinations in between lines PCP-17 and PCP-19, PCP-17 and PCP-9, PCP-17 and PCP-28, PCP-19 and PCP-11, PCP-14 and PCP-9 and PCP-23 and PCP-10 may be utilized in future improvement programme of pointed gourd.
