Amazon (Compound Hybrid)
This variety comes from the crossing of E. oleifera mother palms originating from native palms of the Manaus region, Brazil, with paternal lines (pisifera) originated from the successive backcrossing of a natural hybrid (E. guineensis x E. oleifera) with E. guineensis lines, known as compact palms. Therefore, Amazon is a compound interspecific hybrid with 56.25% oleifera genes. The commercial seeds of this variety come from the crossing of Manaus mother palms of the second filial generation (F2), with fathers from the advanced populations (third and fourth generation) of "compact" origin.
Amazon palms are highly tolerant to bud rots present in several regions of Central and South America and because they present inflorescences with very low androgyny, they are much less attractive for the vector of the causal agent of sudden wilting (Phytomonas sp.). This hybrid also has the advantage of having shorter leaves than other interspecific hybrids, so they can be planted at a higher density. In addition, the harvesting of Amazon is facilitated because the petiole of its leaves is thinner and natural and assisted pollination are much easier and more efficient due to the low cover of spathes in its bunches.
In areas such as Tumaco, Colombia and San Lorenzo, Ecuador, Amazon is showing high precocity, with the production of fresh fruit bunches in the first years of harvest clearly superior to other OxG hybrids. The commercial extraction of oil from Amazon is around 21% when assisted pollination is carried out, and it is in the range of 25 to 27% when auxin naphthaleneacetic acid (ANA) is applied in addition to pollen. The suggested density for Amazon is 128 palms per hectare.
