Yellow Vein Mosaic Disease of Okra: A Recent Management Technique
Journal Title: International Journal of Plant & Soil Science - Year 2017, Vol 19, Issue 4
Abstract
Yellow vein mosaic is a devastating disease of okra, caused by monopartite and bipartite begomovirus and associate satellites. Yield loss due to this virus is quite high, up to 80-94 percent is reported under heavy infection. To control this disease very limited success has been achieved by chemical method, which also is not permanent. Development of host resistance is only reliable mechanism to manage the disease. Availability of source of resistance for the virus is limited in the cultivated species of Okra. However, wild species A. manihot ssp. manihot, A. callei and A. tuberculatus are reported to be resistant against yellow vein mosaic virus. Understanding the genetic regulation along with the molecular mechanism of resistance to okra vein mosaic virus would result in development of resistance cultivars. Also research have been performed from all strategy behind host resistance development, need to emphasis on more advance breeding technique to be utilized for improvement of crop like okra. In this review, attempts were made to compile all information about nature of virus, its transmission through the vector whitefly, congenial environment to disease spread, strategy behind development of host resistant, source of resistant and advance breeding technique.
