AFLP analysis of genetic diversity in determinate and indeterminate snap bean accessions Agronomy
Andrade, Felipe Aranha de; Gonçalves, Leandro Simões Azeredo; Miglioranza, Édison; Ruas, Claudete de Fátima; Ruas, Paulo Mauricio; Takahashi, Lúcia Sadayo Assari.
The present study aimed to estimate and characterize the genetic divergence between determinate and indeterminate snap bean accessions from the Universidade Estadual de Londrina (UEL) germplasm bank based on amplified fragment length polymorphism (AFLP) markers. A total of 40 and 32 accessions with determinate and indeterminate growth habits, respectively, were characterized for this purpose. Seven combinations of primers corresponding to EcoR1 and Mse1 were tested for the AFLP analysis, and the combinations E-AAG/M-CTC, E-ACT/M-CTT and E-ACC/M-CTT were selected. The resulting products were denatured and subjected to capillary electrophoresis. The Jaccard distance was used to estimate the genetic distances between accessions, and the Unweighted Pair...

Genetic diversity of Brassica oleracea var. capitata gene bank accessions assessed by AFLP Electron. J. Biotechnol.
Faltusová,Zuzana; Kuera,Ladislav; Ovesná,Jaroslava.
The genetic diversity of 20 cabbage (Brassica oleracea var. capitata, including sub.var. alba and rubra) cultivars and landraces from the Gene bank of Crop Research Institute was estimated using amplified fragment length polymorphism (AFLP) marker technology. Two cultivars of Brassica pekinensis (syn. Brassica rapa var. pekinensis) were used as outliers in the study. Thirty AFLP primer combinations produced a total of 1084 fragments. A total of 806 fragments, 364 (45%) of them polymorphic, were found across 20 Brassica oleracea var. capitata accessions. The accessions were clustered into two main groups. Special subgroups, reflecting place of origin, were observed within these groups. Ten selective primer pairs were found to be most informative because...
