Summary: The açaí (Euterpe oleracea Mart.) has an ethno-variety white characterized by the absence of anthocyanin in its epicarp, differing from violet açai. White ethno-variety is under strong anthropic pressure, which can lead to genetic erosion. Studies with white açaí that allow the selection of possible cultivars to stimulate their cultivation are scarce. Therefore, this work aimed to verify which characteristics best discriminate selected progenies of white açaí. The experiment contains 52 progenies installed, in a completely randomized design, with ten replications of one plant per plot in a lowland area belonging to Embrapa Amazônia Oriental. The characteristics evaluated were total bunch eight (PTC) in kilogram; fruit weight per bunch (PFC) in kilogram; fruit yield per bunch (RFC) in %; one hundred fruit weight (PCF) in grams; rachillas number per bunch (NRC); and rachilla length in the bunch (CRC), in centimeter. The conclusions are that there exists a correlation between the characteristics in different intensities through multivariate analysis; the Box Plot indicates that the plants respond to the annual water quantity specifically in the characteristics PTC, CRC, and PFC; for the ADC, the characteristics with the greatest contribution to the variance are PTC, CRC and PFC, being similar for the ACP mainly in the PTC and PFC characteristics; by the canonical Biplot the characteristics PTC, PFC, CRC and NRC are preferentially evaluated, discarding RFC and PCF, reducing the effort to be effective.
