Abstract

In this research a total of 49 Accessions in Oat collection of National Plant Gene Bank of Iran belonging to four species of Avena barbata, A. wiestii, A. fatua and A. sativa were studied. The experiment was performed in an observatory design in research field of Seed and Plant Improvement Institute located in Karaj, Iran. The agromorphological traits were measured according to IBPGR descriptor. Based on Shannon index, lemma color had the largest variety (1. 42). In principal component analysis, the first seven components comprised 68. 43% of total variation. Two Accessions of 439 (A. barbata) and 449 (A. barbata) were the nearest and two Accessions of 447 (A. wiestii) and 115059 (A. wiestii) and were the farthest based on genetic distance. The studied Accessions were placed in five groups by K means clustering method. Three Discriminant functions were developed justifying total variance in data. The first and second Discriminant functions maintained the most distinction between two species of A. barbata and A. sativa and between two species of A. fatua and A. wiestii, respectively. Total results indicated presence of suitable diversity in the studied population based on the measured traits which could be exploited in Oat breeding in future. In addition, the Discriminant functions developed in this research could be used in distinguishing the relating Oat species.
