ESTIMATION OF QUALITATIVE PARAMETERS OF FIBER IN COTTON HYBRIDS GROWN IN DIFFERENT REGIONS OF UZBEKISTAN

An assessment of hybrids medium staple cotton by fiber quality in the Tashkent, Fergana and Kashkadarya regions Republic Uzbekistan has been carried out. Four hybrid combinations different genetic origins were tested. The analysis influence genotype environment on manifestation qualitative parameters (length, specific breaking load, microneir) was High values found with participation wild species G. trilobum Skovsted ruderal form Harknessii Brandg, as well Bukhara-6 varieties. According to three-year experiments, it that variability length is largely influenced unaccounted factors. load a significantly genotype, rather than environment. microneir depends environmental conditions.
