IDENTIFICATION OF HETEROTIC CROSSES IN SESAME (SESAMUM INDICUM)

C.R. Ananda Kumar

Open publisher page 2 citations

Abstract

Nine genotypes, consisting of six cultures (lines) and three varieties (testers) were crossed in line x tester fashion. The 18 hybrids and their parents were used to estimate three types of heterosis for 12 traits, including seed yield. Based on standard heterosis and per se performance, the superior crosses were identified for each trait. The cross TNAU 12 x TMV 3, which showed superior performance in yield and seven yield contributing traits, can be considered as the best combination among the 18 crosses evaluated.
