Resumo(s)
The Aragonez (synonym Tempranillo) is probably the red grape variety with the highest economic importance in the Iberian wine context. With different geographical origins, several clones of this variety are now commercially available in the nursery industry. The genotype x environment interaction becomes relevant in clonal comparison trials. In order to characterize some of these clones already accepted in the certification scheme, in a different environmental context which led to the respective approvals, the clones 13-72 (ES), RJ-24 (ES), RJ-51 (ES), RJ-78 (ES), EAN 56 (PT), EAN 59 (EN) 117 JBP (PT), 106 JBP (PT), 110 JBP (PT), 111 JBP (PT), 114 JBP (PT), 776 (FR) and a selection candidate, breeder number 230 were installed in 2003, on an experimental plot located in Lisboa wine region (39 º 01'46''N and 9 01'35 ''W, 99m). Data were collected in 2009. Yield, number of bunches per vine, weight of bunch, probable alcoholic degree and total acidity revealed significant differences between the clones. Based on measurements of the leaf and seeds, it was possible to classify the clones into different groups. One of the clones displayed characteristics that isolated it from the others in the phenogram.
