DETERMINATION OF GENETIC VARIABILITY BY AFLP AND C-B~DING METHODS IN TETRAPLOID WHEAT (TRITICUM TURGIDUM L.) LANDRACES

Abstract

AFLP provided genetic diversity information for 30 tetraploid wheat (Triticum turgidum
L.) representing fo~r sub regions and four altitude classes. For C-banding 14 accessions and one roltivar
was studied. Genetic distance values between and within accessions were calculated and grouped \ly
regions and altitude classes. For both AFLP and C-banding similarity and dissimilaritY of accessions was
analysed by Unweighted' pair group method with arithmetical average (UPGMA) dendrogram.
Geographic classes did. not show distinct sub groupings. The presence of unique C- bands in Ethiopian
tetraploid wheat might have resulted from recent translocation events
