SUMMARY AND CONCLUSION
Cotton in Egypt ranked first in relation to fiber crops and efforts are exerted toincrease cotton production and quality through agricultural policies and breeding newvarieties.
It is well kuown that the productivity of any variety is the outcome of theinteraction between the genetical constitution and environmental conditions.For thisreason, cotton should be grown under suitable environmental conditions to achievethe higbest yield and the best quality.
Therefore, 30 field experiments were conducted during the three successiveseasons 1992 , 1993 and 1994 at ten different regions:-
-Upper Egypt (Sohag,Assuit,El-Minia and El-Faiyum).
- Southen and Middle Delta (Dakahlia, El-Gharbia and sharkeih.
-Northern Delta (Kafer El-Sheikh,El-Beheira and Damaitta), to evaluate 15cotton genotypes of which twelve are the commercial varieties namely, dendera,Giza45,Giza70,Giza 75,Giza76,Giza 77,Giza 80, Giza 81,Giza 83,Giza 84,Giza 85and Giza 86, in addition to the three promising strains (Giza 75 x Rus.6022),(Giza77 x Giza 45A ) and (Giza 77 x Giza 45B).
Varieties and strains all together were grown following the routine adapted in theexperimental stations. A complete randomized blocks design with four replications incach of the 30 environments (combination often locations in three years).
Variance components and different stability estimates over location and years werecalculated for seed cotton yield and yield components, in addition to fiber propertytraits
