Genetic analysis was performed through sequential model fittings to analyse the variation among generations derived from a cross of two diverse parents Bikaneri Narma and Model for seed cotton yield per plant, number of bolls per plant, boll weight, ginning outturn and lint index.  The analysis indicated that a trigenic epistatic model was most adequate for all the characters to explain inheritance.  Epistasis was found to be an integral part in the genetic control of all the characters studied. The higher magnitude of non-additive genetic component than additive component was observed in most of the characters, though additive component was found significant for seed cotton yield, boll weight and for ginning outturn. The implications of the present study in the improvement of populations derived from this cross are discussed.
