MORPHOLOGICAL CHARACTERIZATION FOR PHENOTYPIC DIVERSITY IN CAPSICUM ANUM GERMPLASM
Nadra Khan
Abstract
The present study was designed to characterize the phenotypic diversity among Capsicum anum germplasm along with standard check variety P6. Evaluation of fruit yield on the bases of morphological parameters especially yield related components were studied. Significant variability was observed between all the traits including plant height (32.4 to 69.3), leaf width and length, number of locules, single fruit weight (0.89 to 100.0), fruit wall thickness (0.5 to 4.8), fruit width and length. The yield was also significant and ranged from 148-1809g plant-1. Clustering exposed a grouping pattern of genotypes based on similarity indices regardless of geographical origin. The average mean performance of cluster for all traits showed that cluster V was a rich cluster with high yield plant-1 (1771.80±7.94 g). The correlation coefficient of yield at (P < 0.01) probability level presented a complex pattern of association. Single fruit weight showed a strong and positive correlation with fruit wall thickness and mature fruit width (r=0.85). Similarly, positive correlation between yield plant-1 and single fruit weight was also observed (r=0.78). The positive association and divergence of these yield contributing components can be utilized for the development of an optimal reliable selection for the crop improvement. Both quantitative and qualitative traits were significant contributors to elucidating the variability among genotypes that will further help the breeders to use these line in crop improvement program for variety of traits especially yield related parameters.
