Abstract | ||||
Four successive pure nuclei of Giza 80 cotton cuiuvar (N <')r'\.) (heir corresponding farmer's seeds (F) were used 10 study the changes thai mIght occur in yield and quality atter using the seeds in general planting. The field experiments were carried out in two different locations (Minya and Sohag) through three successive growing seasons (1997. 1998 and 1999). The experimental design was randomized complete blocks design wilh four replications. , The results indicate that the source of variability among studied genotypes and genotypes by locations interactions were, basically, due to the differences of farmer's seeds (FJ, (N) vs. (F.) and their interactions with locations. It could be also, concluded that the lint percentage and lint index characters considered to be good indicators of degeneration as well as the yarn strength trait; which were affected by the presence of off-type seeds. The increasing of off-type locks percentage exhibited negative effects on lint percentage and lint index characters. The results. also. indicated that the mistakenly handling of the farmer's seeds including off-type seed's in general tanns might cause deterioration during twO years. | ||||
