Genetic variability between and within groups of Euterpe spp. based on microsatellites
The objective of this article is to study the diversity between and within groups of accesses of the Euterpe spp. germoplasm collection of the Agricultural Research and Rural Extension Company of Santa Catarina - Itajaí Experimental Station and to identify dissimilar groups that could guide targeted crossesin order to obtain desirable genotypic combinations. Therefore, 18 microsatellite markers, previously developed for Euterpe edulis Mart., were tested. Six of them - EE03, EE45, EE47, EE52, EE54 and EE59 - were efficient and used to obtain the desired estimates. The average polymorphic information content varied from 0.305 to 0.835. Trought the variation analysis, variation values of 13% were obtained between the groups, 40 and 47% within and between the accessions. The Bayesian Method indicated the formation of four groups and from the dendogram with the Ward method, 50% of the dissimilarity value was possible to illustrate them, besides indicating the accesses with low dissimilarity (≤ 10%). The diversity found allows the orientation of directed crosses, both for intra and interspecific hybrids formation and for backcrossing.
