Author(s): Aradhna Suman, SS Surin and Ekhlaque Ahmad
Abstract: Finger millet is an important crop in the developing world especially in Africa and Asia. The aim of this study was to characterize 55 finger millet genotypes using multivariate analysis which is an important statistical tool through which we can easily assesses important polygenic characters which are of great importance in a plant breeding programme. The principal component analysis revealed that the first 4 components with Eigen value of greater than 1.33 contributed about 66.54% of total variability. The proportions of the total variance attributable to the first 4 principal components were 33.61, 12.91, 12.14 and 7.87% respectively. The characters including grain yield per plant, 1000-grain weight, productive tillers per plant, days to flowering, days to maturity, finger number per panicle, finger length and finger width were the most important traits contributing for the overall variability. This implied that these traits should be given emphasis in finger millet improvement programme.
