Genetic variation and association among nine characters were studied in 34 advanced breeding lines of groundnut for WUE and yield related traits during summer 2015. Higher estimates of PCV and GCV were recorded for Pod Yield per plant followed by Kernel Yield per plant and Pods per plant indicating the presence of sufficient variability between advanced breeding lines. High heritability with high GAM was observed for yield related traits and SLA; high heritability and low GAM for SCMR, days to first flowering and primary branches per plant indicated the involvement of additive and non-additive gene action. SCMR and yield related traits had strong positive association with pod yield per plant where as SLA exhibited strong negative association with pod yield per plant. | Study of genetic variability and character association for water use efficiency wue and yield related traits advance breeding lines of groundnut Arachis hypogea L.
