The present study was conducted to find out the Fiber quality traits under different environments quality in three varieties H 1098 – I, H 1300 and H 1316 under six environments (three sowing periods . early, normal and late sown conditions in year 2015 & 2016). Observations were recorded for four fiber quality traits viz. span length (mm), fiber strength (g/tex), micronaire value (μg/inch) and fiber uniformity (%). Fiber length ranges from UI ranges from 81- . Strength ranges from . Micronaire value ranges from - . Fiber quality traits were higher in early sown conditions. | Fiber quality traits under different environments sowing conditions in upland cotton Gossypium hirsutum L.
