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

FULL TEXT:

Abstract

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