However, there are few studies on genetic divergence of wheat genotypes concerning lodging-related traits. Therefore, the objectives of this study were to estimate the genetic dissimilarity of 14 wheat genotypes based on lodging-related traits, the relative contribution of the traits to the dissimilarity, and the most promising hybrid combinations. Fourteen traits were evaluated and subjected to canonical variable analysis, Mahalanobis' distance, and Tocher's and UPGMA clustering algorithms. The high divergence detected among genotypes indicated the presence of genetic variability in the traits of interest. The genotypes TB951 and Rubi presented the greatest dissimilarity while Rubi and BR119 were the most similar. Best parents for controlled crosses based on the different analyses were TB951 and ORI for either crossing with each other or with the other tested genotypes.  aTrigo  aCoeficiente de resistência do colmo ao acamamento  aCulm lodging-resistance coefficient  aDissimilarity measures  aMedidas de dissimilaridade  aTriticum aestivum L1 aCARVALHO, F.
