There exists a lot of controversy regarding the prevalence of strains in the various parts of the world. In India, however, scant information is available about the prevalence of biovars/races and strains in various parts of the country. Understanding local pathogen genetic diversity is the first step in a successful breeding and integrated disease management programme. One of the purposes of the present investigation on six isolates of R. solanacearum causing wilt on tomato and brinjal isolated from different agro-climatic zones of Karnataka is to characterize then into races, biovars and phylotype. |
