Abstract

Gene action for nodulation associated with biological nitrogen fixation has been studied in groundnut. Both additive and non-additive gene interactions are prevalent for nodule number/plant, nodule dry weight/plant, average weight of nodules and nitrogenase activity of the nodules. The genotypes ‘Gunajato’ and ICGV-86055 were the best general combiners for nodule characters and nitrogenase activity in the nodules. The cross ICGV-86055 x EC-21989 appeared to be the promising combination for high nodule number and nitrogenase activity.
