EVALUATION OF OKRA GENOTYPES FOR YELLOW VEIN MOSAIC RESISTANCE

Abstract

One hundred fifty seven germplasm lines of okra including some wild related species were evaluated for resistance against yellow vein mosaic disease under natural epiphytotic conditions. Three accessions of A. tetraphyUus, three accessions of A. ficulneus and one accession each of A. manihot ssp manihot, Hibiscus panduraeformis and H. vitifolius were observed to be completely free from the disease. Most of the accessions of A. esculentus and all the five accessions of A. tuberculatus were highly susceptible to the yellow vein mosaic disease
