Online published on 2 January, 2017. Abstract Variability is the most important characteristic feature of any population therefore estimation of genetic variability is an important prerequisite for realizing response to selection as the progress in breeding depend upon its amount, nature and magnitude. The breeder should have the capabilityof distinguishing thegenetic andnon-genetic components of variation occurring in a population. In the present investigation, a similar analysis of variability along with the findings of mean and Range was carried out for 13 physiological traits in eight parental lines and twenty eight crosses derived from these parental lines. Significant variations in all the traits were obtained except Stomatal conductance. Among the 8 parental lines and 28 crosses, Narendra Dharidar, Pusa Santushti, Pusa Samrat and several crosses derived from these parents exhibited higher values for most of the physiological traits.
