Abstract

The ear weight, grain yield and tiller number in pearl millet exhibited higher degree of heterosis. Inbreeding depression was higher for grain yield in BxB series than in RxR series. Heterosis for grain yield was retained to a great extent in the F₂ of cross L 111 B x J 126 D2B. A few three-way crosses combining superior attributes were identified. Superiority of three-way crosses over single crosses were observed for important yield attributes indicating the possibility of deriving superior recombinants.

Keywords: Pearl millet, Heterosis, Recombination.
