Abstract
This study aimed to clear the interaction between the genotypes and environment on the performance of genotypes. Also to identificy the relationship among the current studied traits and the range of similarity between the genotypes. Thirty-five new cotton strains descending from fourteen Egyptian cotton crosses as well as five check varieties were included in Trial (A) were sown 2011 at Kafr El-Sheikh. According to the data of yield components and fiber traits, twenty strains were selected for sowing in the next season at three locations in trial (B) at 2012 season. With respect to multivariate analysis data four strains, numbered 12, 17, 19 and 20 which were derived from [(G. 70 x Pima S6) x G. 89 x G. 86)], (Pima S7 x G. 92), (G. 67 x Pima S6) x G.92, G.88 x (G.86 x G. 45) genotypes. These genotypes proved to be good substitutes to the genotypes G.87, promising cross {[G.84 x (G.70 x G.51B)] x S62}, G.88 and G.93 respectively. Estimation of variance component indicated that genetic components were more important than the components of genetic interaction. Heritability of yield components was relatively high (over 50%). The genetic variability was low. Stepwise analysis indicated that boll weight and earliness were the main characters responsible for yield performance. Also the data indicated that the traits fiber length (Upper Half Mean) and fiber strength were the main components for yarn strength.
