| Abstract | ||
| Ten Egyptian cotton genotypes belong to long staple cotton were evaluated during the two successive seasons at five locations represented Middle and Upper Egypt (Beni Souef - El-Fayuom – Assiut – Sohag and Luxor) to estimate the effects of genotypes, locations, years and the interaction between them. The effects of genotypes and environments were significant for all the traits studied, except Upper half mean (UHM) which recorded significant difference mean squares only for locations. Years effects were highly significant for all the traits studied, except for seed index (SI), lint index (LI), Micronair reading (Mic) and Yarn strength (Y.St). However, the first order interaction genotype x environments (G x L) was significant and highly significant for all the traits studied, except for lint percentage (L %). The second order interactions genotypes x environments x years interaction (G x L x Y) were highly significant for all the traits studied, except for Micronair reading (Mic). All cotton genotypes produced seed cotton yield (SCY) and lint yield (LY) compared with Giza 90 and Giza 80. The variation between traits from environment to another may be due to the differences in climatical conditions from year to another. | ||
