Studies on Heterosis in Sesame (Sesamum indicum L.)

Abstract

Eight parents of different geographical ongln viz., C01, VRI1, TMV3, S13216, YLM123, SI42, SVPR1, and AHT123 of sesame (Sesamum indicum L.) genotypes were crossed in a half diallel fashion during kharif, 2000 to obtain 28 hybrid combinations. These 28 F1 hybrids along with their eight parents were sown in randomized block design with three replications during Rabi, 2000. Each entry was raised in a row of 3m length and spaced 30 cm apart. Plant to plant distance within row was 30 cm. Ten plants in each replication at the middle of the row were selected at random in each genotype and observations were recorded on yield and other yield related characters. The extent of heterosis over mid-parent, better parent and standard parent (C01) were estimated.
