Occurrence of albinism and estimative of endogamy coefficient in an population of Euterpe edulis Mart.

Abstract

The aim of present research was to verify the occurrence of albinism character and to estimate the coefficient of endogamy of a juçara palm (Euterpe edulis Mart.) population. On this context, were evaluated fifteen free pollination progenies. The progeny test showed that 13.3% of the seed trees presented albino seedlings and therefore the heterozygous for the characteristic. Based on the ratio between albino and normal seedlings, was estematel that the average tax of self-fertilization was 10.0%. The average value of the endogamy coefficient was 0.05. These values are considered the above of the limits for an alogamous species.

Key words:
Juçara palm; free pollination progenies; partial self.
