In this paper are studied the phenotypic differences between inbred isonuclear lines obtained by transformation through backcross of the genotypes TC 209, TC 316, TC 243, TC 221, TC 367 and D 105, during the year 2008. Were subjected to analysis the following characters: plant height, height of insertion of principal ear, the total number of leaves/ plant, number of ramifications/ tassel. It was also determined the stalk lodging of plants and the vegetation period of plants. By changing the cytoplasm, were observed favourable influence in terms of plant height, the stalk lodging of plants and resistance of the ear to Fusarium sp.
