| Abstract: | Genetic diversity in 29 prominent YT series sugarcane varieties was studied using 9 pairs of polymorphism primers selected from 30 pairs of AFLP primers.The results showed that the average polymorphic loci per pair of AFLP primers was 62,and percentage of polymorphism loci was 81.7%.The value of dices genetic similarity index of 29 varieties varied from 0.4436 to 0.8463,with an average of 0.7042,which implied that the genetic diversity among the YT varieties analysed was at middle level.Genetic similarity c... |
