Abstract | ||
An experiment was performed using 121 genotypes to study genetic diversity in yield and its components, oil and protein_content and some phonological and qualitative traits among Iranian landrace populations of safflower (Carthamus tinctorius L.). The study was carried out in 1996 at the Research Station of Agricultural College of Tehran University in Karaj using a simple lattice design. This experiment contained 12 foreign cultivars to be compared with Iranian gennplasm. Fourteen quantitative and six qualitative traits were recorded for all genotypes. Analysis of variance showed significant differences in all quantitative traits among treatments. Treatn1ent means for yield per plant were compared using Duncan's test. Descriptive statistics such as standard deviation and coefficient of variation were found for all traits. Iranian population had maximum values for all traits except for seed oil content. Tomejic had maximum oil content in seed (37.40/0). A genotype from Dashtestan exhibited the minimum plant height (40.4 cm) and another one from Mehriz was of the minimum days to physiological maturity (98.2). A genotype from Tabriz was of the maximum yield per plant (29.6 g) The maximum coefficient of variation (CV) was obtained for number of seeds per plant, and minimum CV was for seed protein content (22.20/0 and 3.950/0 respectively). All 121 genotypes were grouped into nine clusters according to cluster analysis using Ward's rnethod and Euclidian distances, and then cluster profiles were extracted. Ranging of some foreign cultivars with clusters related to Iranian landraces showes that they are of the same origin and the clear fact that these foreign cultivars must have originated from Iran. | ||
