Okra yellow vein mosaic virus

Screening of okra genotypes was carried out under four different environments for shoot and fruit borer, yellow vein mosaic virus disease and enation leaf curl virus disease. The genotypes responded differently to different environments against different insect-pests and diseases. None of the genotype was found free from shoot and fruit borer infection, YVMV and ELCV incidence. However the genotypes that were found with some degree of resistance might be used for future breeding programmes.

Studies were conducted on the performance and morphological characterization of okra for yield and YVMV disease. None of the genotypes found complete free from YVMV infection. However, on scoring test few of them got resistant mark for YVMV like IIHR 129, IIHR-123, and IIHR 120. The characters like plant height, plant canopy, fruit yield per plant, PDI and CI have found wide variation. The character’s association revealed that the association of traits is not only due to genes but also due to the favorable impact of environment.

A field experiment was carried out to screen 18 okra genotypes for YVMV resistance. The per cent plant infection and the reaction of the genotypes were assessed based on the disease incidence and response value assigned by each severity grade.

In the present cytopathological study, phloem cells of diseased mid-vein retained the Azure A stain indicating the presence of foreign deoxy-ribo-nucleoprotein in comparison to healthy one. Inclusion bodies were found associated with the nucleus of diseased mid-vein phloem cells.

Field experiments were conducted during Kharif 2016 and 2017 to manage yellow vein mosaic virus in Okra with seven modules along with one control. The module consists of use of either seed treatment or yellow sticky trap singly or in combination with neem oil (bio-pesticide), one insect growth regulator and two new generation insecticides to manage the vector population of whitefly which transmit the disease.

Experiment under field condition was conducted to test the effect of insecticides against whiteflies checking the incidence of yellow vein mosaic virus (YVMV) on okra at Indian Agriculture Research Institute, Regional Station, College of Agriculture, Pune. The present study conducted in randomized block design with eight treatments. The seven insecticides were evaluated against whiteflies checking the yellow vein mosaic virus (YVMV) incidence .The observations on whiteflies mortality and incidence of YVMV incidence recorded at 3, 7 and 14 days after each spray.

This study was undertaken to find out the potential source of resistance of okra to yellow vein mosaic virus under natural epiphytic condition. The experiment was conducted with ten genotypes/cultivars at Main Vegetable Research Station and Department of Biochemistry, B.A. College of Agriculture, Anand Agricultural University, Anand. Out of ten genotypes/cultivars GAO-5 was registered with the higher of peroxidase and polyphenol oxidase activities and minimum number of whitefly population at 35 and 60 days after germination (DAS) as compared to rest of all genotypes.

Okra [Abelmoschus esculentus (L.) Moench], is an important crop which is widely cultivated in different parts of the world mostly for human consumption and also for industrial use as fibre. The okra production in India, is hindered by occurrence viral diseases, like Yellow Vein Mosaic Virus (YVMV) disease and Okra Enation Leaf Curl Virus (OELCV) disease, spread by an insect vector, namely whitefly (Bemisia tabaci Gen), which affect okra production in terms of yield and fruit quality as well.

Genetic variability analysis on 29 genotypes of okra revealed high magnitude of genetic variability and high degree of transmission of majority of the growth, earliness and yield associated traits under study. High magnitude of genotypic coefficient of variation (>20%) for number of marketable fruits per plant, marketable yield per plant and yellow vein mosaic virus infestation indicated high degree of genetic variability offering great scope for selection of these characters.

Okra (Abelmoschus esculentus L.), locally known as Bhendi or ladies finger, is one of the most important vegetable crop grown in AP in all the seasons. Presently okra is grown in an area of twenty three thousand hectares and production is estimated at about 4.39 metric tonnes. The major problem in okra is yellow vein mosaic virus. The main area is occupied by hybrids from private sector. Different cultivars require different climatic condition and the performance of these entries depend on their adoptability to a particular climate and soil conditions.
