“…Breeders have made crosses between selected but restricted number of double low rapeseed genotypes within the breeding gene pool. Today, molecular restriction fragment length polymorphism, RAPD, AFLP, single sequence repeat, and single-nucleotide polymorphism markers have been extensively used for the estimation of genetic distance or genetic similarity and provide more information than is available from pedigree information (Irzykowska and Bocianowski, 2008;Krzymińska et al, 2008;Wolko et al, 2010;Bus et al, 2011;Bocianowski and Seidler-Łożykowska, 2012;Irzykowska et al, 2012Irzykowska et al, , 2013Seidler-Łożykowska et al, 2014;Varghese et al, 2014;Abbasi et al, 2015). The objective of this study was to characterize the levels and patterns of genetic similarity among the 101 B. napus genotypes of different origin using selected AFLP primer combinations.…”
