| Abstract | ||||
| This study was carried out at the Plant Production Department, Faculty of Agriculture (Saba-Basha), Alexandria University, Egypt and the Cotton Research Institute, ARC, Giza, Egypt. Six commercial Egyptian cotton varieties were under study :Giza 87,Giza 96, Giza 94, Giza 86, Giza 95 and Giza 90. Additionally, three lint cotton grades were estimated for each variety, namely: Good /Fully Good (G/FG), Good +1/4(G+1/4) and Good (G) during the three consecutive seasons 2017, 2018 and 2019 while HVI 1000 (classing) was used for analyzing and measuring the fiber quality parameters. A highly significant difference for the mean squares of the quality parameters for the cotton varieties under study was observed. As well as the three cotton grades and the three growing seasons showed similar behavior for all the cotton fiber properties of the varieties understudy with an exception for the degree of yellowness (+b), fiber length (Upper Half Mean Length – UHML( mm)) and spinning consistency index (SCI) that revealed insignificant differences in the growing seasons. The mean squares of cotton varieties for all studied fiber properties were highly significant differences as well as the three cotton grades and the three growing seasons mannered the same trend for all studied fiber properties as cotton varieties except yellowness degree, fiber length (U.H.M.L) and spinning constant index (SCI) revealed insignificant differences in the growing seasons.Growing seasons (S) had a highly significant effect on all studied fiber properties i.e. the micronaire reading, maturity index, uniformity index, fiber strength, fiber elongation, short fiber index, reflectance degree and degree of yellowness. | ||||
