摘要：
Lentil production has been increasing in Brazil, due to strong national and international demand. Despite the economic importance, few cultivars are available on the Brazilian market. The aim of this study was to evaluate 48 lentil inbred lines and one commercial cultivar (Silvina), based on morpho-agronomic traits and to identify genotypes which can be used in a plant breeding program. Twentyone morpho-agronomic descriptors (nine qualitative and twelve quantitative) were used. The descriptors showed genetic variability among the genotypes. Clustering techniques using characterization data allowed to identify genetically divergent genotypes as well as identify superior genotypes in relation to agronomic traits: FLIP2010-8L and FLIP2010-12L (similarity group I), FLIP2010-99L, FLIP2010-20L and FLIP2010-106L (group II), FLIP90-25L and 6031 (group III), FLIP2007-16L (group IV) and the commercial cultivar Silvina (group V). We concluded that these genotypes have the potential to be used in lentil breeding programs.
