Abstract
Flowering behavior and fiber quality traits were analyzed of six Gossypium hirsutum L. varieties and one G. barbadense
variety that were cultivated in two environmentally different locations. Records of days after planting (DAP) at first floral
bud emergence, DAP at first floral opening, plant height at first flower and nodes above white flower (NAWF) were analyzed
statistically to study flowering behavior in both locations. Fiber traits were tested and records of micronaire, fiber length,
strength, cohesion, elongation, ginning percentage, and weight of seed cotton were statistically analyzed to look for
significant differences and correlations. Earliness and a decline in fiber strength, and fiber cohesion were obtained in
varieties cultivated in Soujeh accompanied with an increase in ginning percentages. Uniquely, fiber elongation showed no
significant differences in varieties between the two environments in both seasons. Our results indicated that stability in some
fiber traits such as, micronaire, fiber length, strength and cohesion was a variety specific. Evidently, fiber elongation in our
work was not affected by cultivation managements and environmental conditions which suggest the solid genetic bases that
control this trait.
