| description | The present study was carried out to estimate some genetic parameters and apply the principal
components technique as a support for selection of several traits in erva-mate. Heritability estimates were
significant for most of the evaluated traits suggesting possibility of great genetic gains with simple selection
techniques. The shaft height trait showed high coefficient of variation, low heritability and low correlation
with the other ones. Beside that, this trait showed to have the lowest contribution to the total variation of the
data, as demonstrated by principal components, and could be discarded. Plant height and crown diameter, on
the other hand, accounted for the most part of the detected variation. |
