The present study was undertaken to identify potential parents and superior cross combinations for yield and other yield contributing characters for improvement in okra. Eleven bhendi genotypes were crossed in line x tester fashion (include direct crosses) in two replications in randomised block design for eleven characters. The results revealed that the highest and significant average heterosis was recorded by 38HU X 11-6 (55.07%) with heterobeltiosis (53.07%) and standard heterosis (36.42%) followed by 38HU X 11-14 (44.98%) with heterobeltiosis (36.65%) and standard heterosis (37.6%) and 38HU X 14-11-5 (32.77%) with heterobeltiosis (19.61%) and standard heterosis (32.97%) for yield and yield contributing traits. High estimates of heterosis obtain in hybrid combinations revealed considerable genetic divergence among parental lines.

Key words: Line X Tester, F1 hybrid, Averageheterosis, Heterobeltiosis, Standard heterosis.
