Resumo: The cassava agricultural exploitation has an important contribution to small farmer because this culture is characterized by easy propagation, large adaptation to several climates and soils, low production’s price and it allowed a whole plant utilization (aerial matter and roots) and, at this moment, the industrial transformation is getting more interesting for starch uses and bioethanol production. This trial aimed to test 19 cultivars/selections, in Rio Pardo, Rio Grande do Sul, using randomized block experimental design, with three replicates. The characteristics evaluated were: plant height (cm), leaves maintenance percentage, stem number per plants, number and weight of roots per plant and root starch percentage. When we take consideration about fresh matter production (plant height, leaves maintenance percentage and stem number per plants) results showed that S 2-11-34, S 60-10 e S 5-77 selections had best performance; to roots production (number and weight roots per plant and starch percentage) “Mantiqueira”, “RS 13” e “RS 14” cultivars and S 60-10 selection were detached. In this production cycle the starch percentage had little variation among evaluated genotypes.

O cultivo de mandioca tem uma contribuição importante para a agricultura familiar, por ser uma cultura que se caracteriza pela facilidade de propagação, adaptação a diferentes climas e solos, baixo custo de produção e possibilidade de aproveitamento integral das plantas (parte aérea e raízes) e, além disto, o processamento industrial vem ganhando espaço pelos diversos usos da fécula e produção de biocombustível. Este trabalho teve como objetivo avaliar o desempenho agronômico de 19 cultivares de mandioca, no município de Rio Pardo, RS, usando-se delinea- mento de blocos casualizados, com três repetições. Foram avaliados a altura do dossel, o percentual de manutenção das folhas, o número de hastes produzidas, o peso e número de raízes e o percentual de amido das raízes. Os dados obtidos mostram que, ao considerar as variáveis ligadas à produção de massa verde (altura do dossel, percentual de manutenção de folhas e número de hastes/planta), destacaram-se as seleções S 2-11-34, S 60-10 e S 5-77; para as variáveis ligadas à produção de raízes (número e peso de raízes/planta e teor de amido), destacaram-se “Mantiquei- ra, “RS 13” e “RS 14” e a seleção S 60-10; e que, com um ciclo de produção, o teor de amido apresentou pouca va- riação entre os genótipos avaliados.
