Abstract:
Cultivation of okra in India is seriously affected by Okra Shoot and Fruit Borer, YVMV and also ELCV. Hence, constant research is in progress to identify stable resistance sources against these pest and diseases. Screening of available genetic resources and incorporating the resistant genotypes in the crop improvement programme serves as a potential method in breeding resistant varieties/hybrids. Therefore, in the present study sowing of 40 genotypes of okra comprising 7 lines, 4 testers, their 28 hybrids and one commercial check GJOH-4 was carried out under three different environments to evaluate against OFSB infestation, infection of YVMV and ELCV under natural condition at Regional Horticultural Research Station, NAU, Navsari. None of the hybrids gave immune/resistant reaction for shoot and fruit borer, YVMV and ELCV in all environments. Hence, parents and hybrids showing moderately resistant or tolerance reaction can be used in further breeding programmes to develop varieties/hybrids resistant or tolerant to shoot and fruit borer, YVMV, ELCV along with good agronomic traits.
