Abstract

In this work, the genetic diversity of 13 improved cotton (G. hirsutum L.) varieties which were released for production in Ethiopia were studied using 24 simple sequence repeats DNA markers. A total of 93 alleles, with a range of 2 to 9 and a mean of 3.88 per markers were detected. The polymorphism information content of the markers ranges from 0.13 to 0.80 with a mean of 0. 50. The pair-wise Dice genetic dissimilarity observed among the varieties were in a range of 0.16 to 0.56 and the overall mean was 0.39 indicating modest genetic diversity among released cotton varieties used in this study. Neighbor joining tree showed the varieties could be assigned to three clusters. Overall the result of this study alarms there is a need to introduce more diverse new cotton varieties to production to reduce the possible risk of genetic vulnerability.
