Morphological Characterization of Peanut (Arachis Hypogaea L.) Genotypes
Abstract
The current study was done on peanut genotypes including one check. The aim of this study was to characterize the morphological variance of genotypes using Shannon-Weaver diversity index. The experiment was laid out in a simple lattice design. Among the genotypes about (46.94%) had erect growth habits, followed by (34.69%) decumbent-3, while decumbent-2 (12.24%), procumbent-1 (4.02%) and decumbent-1 was the least (2.04%). The genotypes revealed three different branching patterns such as alternate, sequential, and irregular with flowers on the main stem accounted (14.29%), (53.06%), and (32.65%) respectively. The majority genotypes had red (46.96%) seed coat color followed by purple-red (22.45%). Purple, pink, and tan seed colors accounted for (12.24%), (10.20%), and (6.12%) respectively. The white seed coat color was observed for check. Among the studied trait the seed coat color (H'=1.44) had the highest diversity index, followed by leaf color (H'=1.29), pod beak (H'=1.20) and growth habit (H'=1.19), indicating that the presence of high diversity among genotypes for these traits. The diversity in qualitative traits might be good for varietal preference and its marketability. This genetic variability can be useful for improvement programs.
