Determination of Genetic Improvement on Fiber Quality Traits in Some Cotton Cultivars Released between 1980 and 2009 in Turkey

Abstract

Improvement of fiber quality is one of the priority themes in cotton breeding programs. Therefore, aspect of genetic progress, their rate and determination of correlation among fiber quality traits have an important role for planning future cotton breeding strategies. In this study, forty four cotton (Gossypium hirsutum L.) cultivars, released between 1980 and 2009 in Turkey, were evaluated. High genetic variation was determined among cultivars for the investigated fiber quality traits. During the thirty years of cotton breeding studies, favorable genetic improvements were determined for 32,69 % spinning consistency index, 7,99 % fiber length, 2,96 % fiber uniformity, -39,66 % short fiber content, 21,07 % fiber strength and -12,59 % fiber fineness traits. Among the investigated traits, spinning consistency index, fiber length, fiber strength and fiber uniformity were positively correlated with each other. However, short fiber content and fiber fineness were negatively correlated with the above mentioned 4 fiber quality traits. This result indicated that aforesaid 6 fiber quality traits can be improved simultaneously.
