Carica papaya(L.) is infected by a number of diseases caused by fungi ,bacteria and viruses. Among these ring spot disease caused by Papaya Ring Spot Virus (PRSV) is common and most serious disease recorded from several part of the country. The deviations in meiotic studies specially microsporogenesis leads to infertility of pollen due to deviations in meiotic and post meiotic behaviour of cell division processes that leads to chromosomal aberrations most commonly as sticky chromosome, laggerd chromosome and deviations in meiotic index. This reduction in gametic fertility causes loss in quantity of the fruit. The present study deals with comparative study of post meiotic behaviour between healthy and diseased plants that shows deviations at different stages of microsporogenesis that leads to pollen sterility.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
