| Abstract | ||
| Agropyron pectiniforme having moderate to high yield and quality traits is cultivated for pasture regeneration and forage production in rangelands of Iran. In order to study genetic variability in Agropyron pectiniforme based on morphological traits, 16 populations were examined in the field trial using a complete block design with three replications during 20042005 in Karaj, Iran. Data were collected on heading date, plant height, tiller number, spike length, forage yield, seed yield and thousand grain weights. Results showed significant differences between the populations for all of the recorded traits (P≤0.01). Populations Zangan487, Tabriz-707 and Gorgan-7565 with averaged values of 96 to 119 g/plant and 25 to 33 g/plant had higher forage and seed production, respectively. Among them, Zangan-487 had early maturity date and Tabriz-707 had higher seed thousand grain weights. Phenotypic correlation between forage and seed yield was positively significant (P<0.01). Both traits positively correlated to plant height, tiller number and spike length. The populations were classified into three groups based on cluster analysis. Cluster number 1 contained populations with late maturity and moderate yield. The populations in cluster 2 had higher forage and seed production and populations in cluster 3 were early maturity and low productivity. Distance between the clusters were assessed using principal components analysis (PCA) and Mahalanobis Distance. Result showed higher genetic distance between clusters 2 and 3. It was suggested to use populations located in the separate clusters for improving composite varieties. The population Zangan-487 having higher both forage and seed yield was introduced as promising population for future research. Result of mantel correlation test between population’s geographical origin and matrix genetic distance of morphological traits was not significant. This finding indicated a lack of association between genetic variation and their geographic distribution. It was concluded that morphological traits provide important information for the genetic conservation and utilization of future breeding programs in A. pectiniforme. | ||
