Abstract:

a teramnus spp. collection was studied for a year with the objective of evaluating and selecting the most outstanding accessions of this germplasm. the work was done in 3 x 1 m plots, with space between rows of 2 m, which plants had been established since a previous study. in order to obtain the variability and the relationship among variables, a principal component analysis (pca) was performed; while for grouping the treatments with similar characteristics, regarding the measured and estimated variables, a graphic was made through the result of the pca. the existence of 76,85% of total variability was observed, based on plant height, leafiness, cover, vigor and yield, and the formation of seven groups was identified. it is concluded that there was an acceptable performance of the accessions and those in group ii stood out, mainly t. labialis ciat-926, ciat-21197 and ciat-9128, for which it would be advisable to insert them in the varietal flow and compare them to commercial accessions.
