RESUMO:    Objetivou-se com este trabalho determinar equa&#xE7;&#xF5;es que possibilitem estimar a &#xE1;rea foliar de gen&#xF3;tipos de mandioca a partir de medidas biom&#xE9;tricas das folhas. Foram coletadas folhas de 17 gen&#xF3;tipos de mandioca e mensurados em cada unidade o comprimento, a largura do l&#xF3;bulo central e a &#xE1;rea foliar real. Os gen&#xF3;tipos foram agrupados por meio do m&#xE9;todo  de  an&#xE1;lise  multivariada  UPGMA,  utilizando-se  a  raz&#xE3;o  entre  o  comprimento  do  l&#xF3;bulo central com a largura do mesmo (C / L). Ap&#xF3;s o agrupamento foi realizado o teste de correla&#xE7;&#xE3;o de Pearson entre as medidas biom&#xE9;tricas e a &#xE1;rea foliar real. Foram testados modelos de equa&#xE7;&#xE3;o linear e potencial para os grupos encontrados na an&#xE1;lise de agrupamentos. As  vari&#xE1;veis  biom&#xE9;tricas  que  apresentaram  maior  correla&#xE7;&#xE3;o  com  a  &#xE1;rea  foliar  foram  o  produto do comprimento e a largura do l&#xF3;bulo, e o comprimento do l&#xF3;bulo central. Quatro diferentes grupos foram encontrados, nos quais os modelos de equa&#xE7;&#xE3;o linear se ajustaram melhor quando se aplica o produto entre o comprimento e a largura do l&#xF3;bulo central e os potenciais quando se usa o comprimento do l&#xF3;bulo central.

ABSTRACT:    The objective of this study was to determine equations that allow estimating the leaf area of cassava genotypes from biometric measurements of the leaves. Leaves of 17 cassava genotypes were collected and the length and width of the central lobe and the real leaf area were measured in each unit. The genotypes were grouped using the UPGMA multivariate analysis method, using the ratio between the length and width of the central lobe (C/L). After grouping, Pearson&#x2019;s correlation test was performed between the biometric measurements and the real leaf area. Linear and potential equation models were tested for the groups found through cluster analysis. The biometric variables that showed the greatest correlation with the leaf area were the product of the length and width of the lobe and the length of the central lobe. Four different groups were found, in which the linear equation models  were  best  adjusted  when  using  the  product  between  the  length  and  width  of  the  central lobe and the potentials when using the length of the central lobe.
