Description A study was conducted during 2005–06 to find out the effect of alien cytoplasm in ‘alloplasmic×euplasmic’ hybrids in first experiment, and the effect of alien cytoplasm as well as of alien nuclear genes in the ‘alloplasmic×euplasmic’ and ‘euplasmic×euplasmic’ hybrids, respectively, in the second experiment. The hybrids for both the experiments were produced using line×tester mating system. Yield and contributing traits exhibited superiority of conventional ‘euplasmic×euplasmic’ hybrids over cytoplasmic male sterility based ‘alloplasmic×euplasmic’ hybrids in both the experiments and over the genetic male sterility-based ‘euplasmic×euplasmic’ hybrids in second experiment. Cytoplasmic male sterility-based ‘alloplasmic×euplasmic’ hybrids were superior over the genetic male sterility-based ‘euplasmic×euplasmic’ hybrids in the second experiment for yield and boll weight, however, for fibre quality traits the trend of performance was variable. Alien cytoplasmic and nuclear genes did not exhibit severe deleterious effects for fibre quality related traits, even though a gain was reported in cytoplasmic male sterility based ‘alloplasmic×euplasmic’ hybrids for 2.5% span length and uniformity ratio over the ‘euplasmic×euplasmic’ hybrids in first experiment. In the second experiment, cytoplasmic male sterility-based ‘alloplasmic×euplasmic’ hybrids expressed their superiority over the genetic male sterility-based ‘euplasmic×euplasmic’ hybrids for most of the fibre quality traits. The average performance of conventional euplasmic×euplasmic’ hybrids were unambiguously superior over the two types of hybrids for yield and contributing traits and most of the quality traits.
