Descripción

The objective of this study was to evaluate of the genetic similarity among 129 sugarcane clones. For that, it was evaluated the number of stalks per plot, the average mass of the stalks, the mass of 10 stalks, the medium brix and the brix production in kilograms for each plot. The data were analyzed through several Canonic Variables and Tocher method using the Mahalanobis (D2ii’) distance. The results obtained by Tocher method and graphic dispersion shown that the most dissimilar clone was TUC77519. On the other hand, the most similar clones were RB 975056 and RB 915006. The number of stalks per plot (NSP) and the brix production per kilograms per plot (BKP) were characteristics that most contributed most for the genetic variability.
