Abstract: 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 NBae52cfbe53286d5cccfefd7e7c849693dc19f373.png, a high correlation between TBY and MBW 614e840127aecfe498a8fa8a57ceb18116f2ae19.png and a negative high correlation between NB and MBWb32c9155c44945342ff510a47f83cd04a033ce0a.png. The results indicate a high expectation of gains with selection for TBY.
