Abstract
Different selection methods i e phenotypic individual trait selection, selection index and recurrent selection were used to improve lint yield in three populations of Egyptian cotton, G. 45 x G. 75, G. 87 x G. 89 and G. 86 variety grown in open-pollinated bulks for four years. In population I (G. 45 x G. 75), the direct phenotypic trait selection procedure in F4 generation for lint yield (In.,) was superior to the other selection procedures. Concerning population II (G. 87 x G. 89), the recurrent selection and phenotypic trait selection for bolls/plant (I4) in F4 generation were more efficient than the other selection procedures. Regarding population III (G. 86 open-pollinated cultivar), both recurrent selection and index I, in S2 generation were superior compared with the other selection procedures.
