Conteúdo:

To identify superior genotypes, 42 progenies of interspecific hybrids
between American oil palm and oil palm were evaluated in an area with incidence
of bud rot. The following variables were assessed: total bunch yield
(TBY), number of bunches (NB) and mean bunch weight (MBW) from the third
to the sixth year of cultivation and estimates of genetic parameters obtained
by REML/BLUP procedures. High heritability values of the evaluated traits were
observed. The gain estimates for TBY were 14.49% for the selection of the five
best progenies and 33.36% for the selection of the five best trees, considering
multiplication by cloning. A medium correlation was observed between TBY and
NB (r2 = 0.33±0.021), a high correlation between TBY and MBW (r2 = 0.53±0.019)
and a negative high correlation between NB and MBW (r2 = ?0.60±0.018). The
results indicate a high expectation of gains with selection for TBY.
