Abstract
Two cycles of recurrent selection were applied on a pearl millet (Pennisetum typhoideum Rich.) population sown in late summer. The procedure increased not only the selected characters, grain weight and panicle numbers, but also non-selected characters such as plant height, top weight, harvest index and panicle length. Heritability estimated by the genetic gain of S2 population was 0.47 for number of panicles per plant, 0.67 for pancile weight, 0.47 for grain weight per panicle and 0.90 for grain yield per plant, showing that the further selection for grain yield might be possible. Genetic correlation between grain yield and yield-related traits was high, showing the effectiveness of indirect selection through these yield-related for high grain yield.
