Abstract:

Papaya is an economical fruit crop in Kadapa district of AP and Kodur region is a traditional belt for cultivation from early 1990’s. The cultivation was with dioecious varieties initially and as the time progressed gynodioecious varieties (Taiwan Red lady) were introduced in the Indian market. In Kodur region, the crop directly or indirectly improved the livelihoods of farmers, fruit traders, processing industries, news paper vendors, hoteliers, transporters. The biotic stress disease mainly, Papaya ring spot virus (PRSV) intensity has increased over a period of time due to continuous cultivation of Taiwan Red lady and in majority of the farmers field it has greater impact on yield and was the major reason for reducing the papaya crop from perennial to annual nature which in turn affected different sections of people dependent on this crop. Hence there is a urgent need to introduce varieties showing tolerance to PRSV or shifting to the other crops with equal potential.
