Development of Productive Cotton Cultivars with Increased Fiber Quality for Bukhara Region of Uzbekistan

摘要

Bukhara region is one of the important agricultural regions for Uzbekistan, producing cotton as a leading crop in addition to cereals and horticultural crops. Agricultural production in this region is greatly suffered by soil salinization and water deficit that requires a specific effort in development of adapted crop cultivars for this harsh climatic environment. However, with development of scientific efforts and science-based facility in the provincial regions of Uzbekistan after independence in 1991, cotton breeders of Bukhara research centers took a concentrated effort to develop new cotton varieties, named after the ancient city 'Bukhara', which turned to be highly adapted to this region. These new varieties are 'Bukhara-6', 'Bukhara-8' and 'Bukhara-102' that significantly increased the cotton productivity of the region. The 'Bukhara-6' variety became the leading standard for other varieties of cotton cultivated in Uzbekistan because of its high textile quality among other varieties grown inUzbekistan.
