Variability in selected genotypes of fluted pumpkin (Telfairia occidentalis Hook F.) in Calabar, Cross River State
Main Article Content
Abstract
Fluted pumpkin remains an important vegetable in Nigeria.Assessing genetic variability in this crop provides a basis for selection and breeding purposes. This investigation was carried out to assess genetic variability in selected genotypes of fluted pumpkin in Calabar. The field experiment was laid out in a randomized complete block design (RCBD) with three replications. A total number of seven genotypes was used for this study.The results showed that genotypes varied significantly for some traits under consideration. Among some morphological traits evaluated, significant differences were observed only in leaf area and leaf area index. The heritability values ranged from 79 – 81%. Leaf area and Leaf area index at 6 weeks after planting (WAP) had the highest heritability value of 81%. Similarly, genetic advance as percent of mean (GAM) ranged from 11.29 – 13.63. The highest GAM was recorded in leaf area at 6 WAP.The high heritability and genetic advance observed in leaf area and leaf area index at 6 WAP, suggests that these characters have additive gene effects and can be further evaluated for the improvement of this crop.
