بررسي تنوع مورفولوژيك اكسشن هاي مختلف موسير (Allium hirtifolium Boissier) در استان لرستان

Evaluation of morphological variation in different accession of Allium hirtifolium Boissier from Lorestan Province

In this study since 2004 to 2005, 16 accession of Persian shallots were collected from Lorestan province and evaluated to determine the diversity among them. The studied morphological characters were: Bulb weight, number of bulb, plant height, bulb diameter leaf length and leaf width. Duncanʹs multiple range tests showed that the accession of Persian shallot were significantly different in all evaluated parameters except bulb diameter and leaf length. Correlation coefficients showed that bulb weight was positively correlated with number of bulb (r = 0.474) and bulb diameter (r = 0.624), which is useful for indirect selection of accession with high number of bulb and bulb diameter and therefore high amount of bulb weight. Cluster and principal component analyses based on six morphological traits separated the accession into four main groups, but did not indicate significant relationship between genetic diversity and geographical origins.
