Abstract
Aims: The study was conductedto assessthe variability in reactions of groundnut varieties to groundnut rosette virus isolates from Uganda (Please correct the yellow highlighted sentence). Study Design:The experimental design was randomized complete block design arranged as a split plot with three replications. The main plots were the groundnut varieties while the sub-plot were the groundnut rosette virus isolates collected from central, western and eastern Uganda. Place and Duration of Study:The studywas conducted at the screen house, Kyambogo University, Kampala during 2011 and 2012, respectively Materials andMethods: Non-viliferous aphids obtained from Mukono zonal agricultural research and development institute (MUZARDI) fed on infected groundnut plants collected from central, western and eastern Uganda were used to infect 3 week old groundnut seedlings in a screen house. Results: There were significant variation in reactions (P<0.05) among the groundnut varietiesto groundnut rosette virus isolate s. Similarly, significant variety x isolate interactions were observed for incidence, leaf area index and plant height. Conclusion: This study has shown that there were significant variations in reactions of groundnut varieties to groundnut rosette virus i solates. In general, two groundnut rosette
