Heterosis for Yield and Yield Components in Okra (Abelmoschus esculentus (L.) Moench)

A study of mean and heterosis for yield and yield components was conducted in bhendi using 7 okra genotypes of diverse origin crossed in all possible combinations indicated that manifestation of heterosis over the mid and higher parents was evident for all the characters studied. The study resulted in 33 hybrids to assess mean and heterosis for yield and yield components. Among the 33 hybrids, six heterotic hybrid combinations viz., MF-3 x OHD-1, MF-3 x Varsha Uphar, MF-3 x Arka Anamika, OHD-1 x Varsha Uphar, OHD-1 x Arka Anamikaand Varsha Uphar x Arka Anamika expressed high mean performance as well as heterosis (over best parent) for yield and its components. These crosses could be selected for exploitation of hybrid vigour and commercial utilization. The magnitude of heterosis ranged from 0.49 per cent (MF-3 x MF-1) to 52.22 per cent (Varsha Uphar x Arka Anamika).
