Conteúdo: |
Sweet cassava is a food culture of great importance because it is a source of nutrition and energy for
millions of people in tropical and sub-tropical regions. For that reason, genetic diversity and population
structure studies are necessary in order to obtain more information regarding the evaluated genotypes,
reassuring their use in future breeding programs. The objective of this study was to evaluate the
genetic diversity and population structure of 51 traditional sweet cassava accessions collected in the
Southern of Minas Gerais State, Brazil, using 20 microsatellite markers. All markers used to genotype
the 51 sweet cassava accessions were polymorphic (PIC = 0.4080). Four sub-populations were
identified using different methods (Bayesian analysis and multivariate analysis). The PhiPT (analogous
Wright Fst) index of 0.073 indicated a moderated genetic variability among the studied traditional sweet
cassava accessions. The dissimilarity index ranged from 0.097 to 0.560. Among the most divergent
accessions stands out BGM 690, BGM 655 and BGM 660, which are the most recommended for
obtaining a heterosis in order to increase yield production. |
