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.
