Abstract

Studies with molecular markers have been used in rice breeding programs, particularly AFLP, due
to its high accuracy and reproducibility of generated data. In the present work, 19 rice cultivars from the Germplasm Bank from Epagri and three genotypes F5 with a genetic basis from the cultivars Epagri 108 e Epagri 109 with
introgression of genes from the multi-spikelet genotype were characterized using AFLP. A total of 169 polymorphic markers were detected, generating two homogeneous groups with 17 out of 22 evaluated accesses. Eight out of the ten cultivars released by Epagri, as well as the three F5 genotypes, clustered in the same group, with similarity
greater than 50%. Six of the cultivars are derived from crosses from Ciat, and the other two from crosses from Embrapa/CNPAF, which can explain in part the genetic similarity between them.
