"Phenotypic correlation, path coefficient and multivariate analysis for yield and yield-associated traits in groundnut accessions"^^ . "Yield is a complex quantitative trait largely influenced by the environment.\r\nDirect selection for grain yield is less efficient in improving groundnut productivity.\r\nThe selection efficiency can be enhanced by exploiting the relationship\r\nbetween yield and its related traits. Moreover, the use of genetically diverse parents\r\nis essential to generate genetic variation for successful selection of genotypes in\r\na breeding program. Therefore, the study aimed at analysing the relationship\r\nbetween grain yield and its related traits and determining the morphological\r\ndiversity among selected groundnut genotypes under natural rosette disease (GRD)\r\ninfestation. The genotypes were evaluated in a 7 × 4 alpha lattice design with three\r\nreplications. Data were collected on yield and yield-related traits. Correlation, path\r\ncoefficient and multivariate analyses were done. The results revealed that yield was\r\ndirectly associated with plant height, number of pods per plant, hundred seed\r\nweight, GRD incidence and number of secondary branches. Therefore, these traits\r\nshould be considered in selection when improving groundnut for yield. Cluster\r\nanalysis revealed existence of diversity among the evaluated groundnut genotypes with no influence of geographical origin to the clustering pattern. The Principal\r\nComponents Analysis (PCA) biplot was effective in showing the genetic distance\r\namong the genotypes and the results were comparable with those of the cluster\r\nanalysis. Moreover, Shannon-Weaver diversity indices revealed existence of high\r\ndiversity among the genotypes, an implication that groundnut improvement for\r\nyield is possible through selection in breeding."^^ .
