Short Communications


Silica uptake was studied in dialel cross involving seven genotypes. Maximum profile of this element was found in leaf followed by stem and root. Regarding its uptake both additive and non-additive genes were involved while the former wa higher in magnitude indicating the scope of individual selection in segregating generations. Heterotic effect was also evident. The assessment for efficiency of uptake can be made at an early stage (60 days of growth).
