Assessment of Okra Genotypes for Resistance against Shoot and Fruit Borer, Yellow Vein Mosaic Virus and Enation Leaf Curl Virus under Natural Field Conditions

India is a key player in okra production with Andhra Pradesh leading state in cultivation. However, the crop faces significant challenges from Yellow Vein Mosaic Virus (YVMV) and enation leaf curl virus (ELCV) which severely impact yield and quality. The study conducted at the Vegetable Research Farm, Regional Horticultural Research Station, evaluated 37 okra genotypes for resistance against these biotic stresses. The genotypes, including 8 parents and 28 hybrids were assessed under three different environments in a Randomized Block Design. The results revealed that none of the genotypes were immune to shoot and fruit borer infestation, YVMV and ELCV. However, some hybrids demonstrated resistance or tolerance to these stresses with the top three hybrids displaying high levels of resistance against shoot and fruit borer infestation, moderate resistance against YVMV and high tolerance to ELCV. Nevertheless, none of the hybrids showed consistent immunity across all environments.
