A study concerning the fineness and length of the following international varieties of ramie (Boehmeria nivea Gaud.) is reported: Hakuhi Ibgou; White Skin; Taiwan Hakushi; Shalien n.° 1; Hsi-Ching-Chin-Hsin; Banmethuot; Miyasaki 112; E 47-1; Murakami; P.I. 87.521; Kagisei; and Yilan n.° 1. The study was based on fibers obtained from three month old stalks of the ramie varieties produced in the State of São Paulo, Brazil. The Taiwan Hakushi exceeded the others varieties in average fineness (Nm 1786) and the Hsi-Ching-Chin-Hsin had the lower average fineness (Nm 945). The varieties P.I. 87.521, Banmethuot e Taiwan Hakushi had the lower fiber length (average of 133 mm, 141 mm and 151 mm, respectively). Hakuhi Ibgou, Hsi-Ching-Chin-Hsin and Shalien n.° 1 had the longer fibers (average of 175 mm, respectively). The fibers classified in short, median and long, showed that the varieties of high average length fiber were more uniform than varieties of low average length fiber. The results obtained may be used by the ramie industry for production of different kinds of manufactures and also by the breeders in order to establish any breeding and selection program.
