MANGOVA, M. and I. PETROVA, 2007. Detection of quality diversity of durum wheat (Triticum durum Desf.) using cluster and principal component analyses. Bulg. J. Agric. Sci., 13: 301-308

The present work was carried out to study quality diversity among 15 accessions of durum wheat from the collection of the National Gene bank in Bulgaria. Cluster analysis results showed that accessions Agathe, Mauragani iraclion, No97102050 and the unique Kubanka were more specific. They combine high protein content with a high quality of gluten and are preferable to accessions with high protein and gluten content but insufficiently strong gluten. The results of Principal Component Analysis suggested that the most variable characters were the gluten softening of grain and semolina and the gluten compressibility of grain and semolina. They were responsible for the clustering of accessions in the present study.
