VARIABILITY OF PHENOLOGICAL TRAITS AND VEGETATION PERIOD IN SOFT WHEAT GENOTYPES ACROSS REGIONS
The present study investigated the variability of phenological traits in soft wheat (Triticum aestivum L.) genotypes, particularly
the “emergence-to-heading” phenophase and the overall vegetation period, across different ecological regions. The experiment
was conducted with 50 genotypes in three replications under the conditions of Tashkent, Surkhandarya and Andijan regions.
