Caracterização morfológica de acessos de curauá do banco ativo de germoplasma da Embrapa Amazônia Oriental

Abstract

This work had the purpose to carry out the morphological and agronomical characterization of two curaua accesses groups from active germplasm bank of Eastern Amazon Embrapa. Accesses were evaluated according to the plants age for 6 months with 15 accesses and 12 months with 26 accesses. List of descriptors: leaf (length, width, length / width, number and color).The results were submitted to analyses of variance and Scott-Knott test (p<0.05) and analyses of group and main components. The analyses of variance showed significant differences in both groups. Comparing, simultaneously, the average of variables responses length and length/width observed that plants from group 1 the higher means accesses FMR 2600 and SRR 2500. For the group 2 the accesses PEMATEC R, PAB 900, EMBRAPA R, PPR 400 and ANR 1200 were the highest. Dendrogram among the 15 curaua accesses could be observed that there is one larger group with 13 accesses with 3 subgroup and one smaller group. For group 2 it was observed the formation of two larger groups with many subgroups. The analyze of main components showed similar groups as showed in the dendrogram.
