Abstract

In the article are presented results of study of the cotton plant gene pool after 2009 – 2011 in Institute of the Irrigated Agriculture. The sources of precocity, productivity, accessions, which are suitable to the mechanized harvesting and with the good high-quality indexes of fibre are selected. It is determined that highly technological standards have insufficient length of fibre. It is offered ways of improvement of it quality. The results of study of introductive material are presented.. The vegetation period of new accessions is hesitated from 115 to 127 days. On the trait of precocity are selected: Chirpan 539(UF0800018), Natasha (UF0800212) and Helius (Bulgaria),. on ever-higher attachment of first simpodii: Avanguard 264 (UF0800020) 13 cm, Vega (UF0800278) (12,8 cm) and Natasha (11,0 cm), Pidozerskiy 4 (UF0800031). The cottonwool productivity for Chirpan 539 (26,5g) and Trakiya (UF0800049) - 29,1g was high then standard (23,5 g). The investigation of introducted accessions will usrful for addition of base collection and for breeding practice.
