Heritability and correlation studies of fatty acid composition within Hyoscyamus accessions

Abstract:In the present study, the variability among the 14 accessions was assessed through analysis of variance, which showed significant differences among the accessions for 11 fatty acids and oil content. Variability in different traits was due to genotypic effects, since phenotypic coefficient of variation (PCV) was higher than those of genotypic coefficient of variation (GCV) with very small differences. The range of genetic similarity was obtained between 0.05 and 0.99 among various comparisons. Fatty acid composition significantly varied with locations. The dendrogram revealed that genotypes h1, h2, h3, h4, h7, h8, h9, h10, h13 and h14 are the most distantly related. Hence, these genotypes could be considered for future breeding programs to create higher amount of genetic variability in Iranian germplasm of Hyoscyamus
