Description
Summary:In the present investigation, a study was undertaken at the Department of Agricultural Botany, Annamalai University during the year 2006 – 2008to identify potential parents and superior cross combinations for yield improvement in Okra. Six bhendi genotypes viz., Girija Vikas, MDU 1,Hissar Unnath, Arka Abhay and EC 305623 were crossed in full diallel fashion (including the reciprocals). The eight characters observedincluded days to 50 per cent flowering, plant height, number of branches per plant, number of fruits per plant, fruit length, fruit girth, individualfruit weight, fruit yield per plant. The results revealed that the standard heterosis for fruit yield per plant was maximum in the hybrid MDU 1 xHissar Unnath, with a value of 65.23 per cent. This hybrid recorded high standard heterosis for all the characters except number of branches perplant and individual fruit weight.
