Studying genetic variation is regarded as essential for
understanding the gene pool and for breeding new superior
cultivars, and is also necessary to identify the affinities and
similarities among plants for a more comprehensive comparison
of cultivars (Khoshroo et al. 2011). Different methods,
such as protein and DNA molecular markers and cytogenetic,
biochemical and morphological properties, have been used
for the analysis of genetic variation and cultivar identification
(Collard and Mackill 2008; Jaradat and Shahid 2006;
Malik et al. 2009; Miernyk and Hajduch 2011; Pettengill and
Neel 2008; Tavaud-Pirra et al. 2009). As the major objective
of this study, we attempted to compare the relationship of
Korean soybean landraces collected from eight locations
using protein profiling electrophoresis (PPE) and morphological
traits. Our results could assist researchers in obtaining a
better perspective regarding the identification and classification
of Korean soybean landraces.
