Heterosis and per se performance in kharif sesame (Sesamum indicum L.)

A field experiment was conducted at Agricultural Research Station, Yellamanchili during kharif 2008 on heterosis and per se performance in sesame (Sesamum indicum L.). Six parents viz., G-2, S. I. 3012, E-8, M. T. 101, Kayankulam-1 and Thilothama were crossed in diallel fashion without reciprocals and the resultant 15 F(1)s alongwith the parents were evaluated in randomized block design. It was found that the per se performance and heterosis over mid, better and standard parents were high in respect of seed yield in the cross E-8/M. T. 101 followed by G-2/M. T. 101 and S. I. 3012/M. T. 101. The cross E-8/M. T. 101 also recorded early duration with highest number of branches and tallest plant height.
