Plant height and peduncle length were conditioned by partial dominance with additive type of gene action while economic yield per plant, biological yield per plant and harvest index were controlled by over dominance type of gene action. Non allelic interaction was absent for all these traits.]]>Hayman, B.I.,195439789809Hayman, B.I., 1958436385Hussain, M., N.1. Khan, S.S.D.
