Abstract

In this article, the correlation relationships between economically important traits in lines isolated in F7 hybrid combinations were evaluated. In particular, the relationship between fiber yield, the weight of raw cotton per boll, the weight of 1000 seeds, and fiber length was analyzed. The results showed that in some lines, positive, and in others, negative relationships were observed between the traits. Also, a moderate positive correlation was noted between fiber length and fiber yield in lines L-863-66 (R=0.65), L-556-59 (R=0.42), L-496-99 (R=0.39), and at the same time, fiber length and the weight of raw cotton per boll in lines L-496-99 (R=0.56), L-693-95 (R=0.40), L-317-20 (R=0.34). According to the analysis of the results, the strength of the correlation indicates that in breeding, it is necessary to simultaneously improve several traits or select them taking into account the negative ones among individual traits.
