In the present study 70 pearl millet inbred lines were evaluated for 21 quantitative traits. Analysis of variance for 70 pearl
millet inbred lines revealed significant differences among the germplasm lines for all the 21 traits studied indicating the presence of considerable genetic variability among the lines studied. The high estimates of GCV and PCV recorded for grain yield plant-1 followed by 1000 grain weight, panicle weight, green fodder yield plant-1, dry fodder yield plant-1 and harvest index indicated the presence of high genetic variability for these characters. High heritability coupled with high genetic advance as per cent of mean was recorded for days to 50% flowering, spike length, spike girth, number of productive tillers plant-1, plant height, 1000 grain, panicle weight, green fodder yield plant-1, dry fodder yield plant-1, threshing percentage, harvest index and grain yield plant-1 indicating the preponderance of additive gene action. These characters can be further improved by following simple selection procedure.
