The present investigation was carried out on 30 genotypes of okra to study powdery mildew and their morphological characterization under natural field conditions at Palampur aiming at the development of high yielding, powdery mildew resistant lines of okra. Based upon the mean performance, genotypes 9801, Kashi Vibhuti, DPO-5, Palam Komal and Punjab Suhawani were found to be top yielders and resistant to powdery mildew disease. All the genotypes taken for study were found to be resistant and moderately resistant to powdery mildew disease except Kashi Pragati, Shitla Uphar, Shitla Jyoti, Kashi Satdhari, DPO-6, DPO-8, DPO-9, DPO-13, DPO-19 and Punjab-8. Okra germplasm contained sufficient genetic variability and can be used for crop improvement. Coincidently, among the top five high yielding lines most showed dark green or green coloured pods along with downy pubescence. Thus, these genotypes can be further used for breeding programmes and can be directly used after multi-location testing as these possess inherent ability to high yielding, superior quality along with powdery mildew resistance.

Okra germplasm contained sufficient genetic variability and can be used for crop improvement. Coincidently, among the top five high yielding lines most showed dark green or green coloured pods along with downy pubescence. Thus, these genotypes can be further used for breeding programmes and can be directly used after multi-location testing as these possess inherent ability to high yielding, superior quality along with powdery mildew resistance.
