A population of 233 genotypes of ramie (Boehmeria nivea Gaud.) was studied for selection and establishment of high fiber yielding clones. The genotypes originated of self-pollinated plants of the Murakami variety and crossings between this variety with Yilan n.° 1, Banmethuot, and London varieties were classified in four class according to the leaf and leaf-stalk color. In three successive harvests, only 67 genotypes produced long stalks which were studied with regard to number and weight - green long stalk with leaves and without leaves, green short stalk with leaves - weight of dry fibers, fibre content in green long stalk with and without leaves and length of long stalk. In the third harvest five long stalks of each genotype were subjected to the following determinations: weight green-stalk with leaves and without leaves, two hundred fifty milimeters of green and dry stalk, dry fiber - content - fiber in green stalk and dry stalk, leaves and humidity stalk - and diameter and length of stalks. For the most part of the characters studied genotypes of identical origin differed significantly. The genotype classes of identical origin had different behaviour when they were confronted two and two. Crossing Murakami with Banmethuot gave the more numerous producible genotypes and those that presented the best values for some characters tested. Eighteen genotypes that presented the best characters, principally in relation to dry fiber production, were selected to establish clones.
