Abstract

In order to evaluate the adaptation and ornamental potential of Allium spp endemic to Iran, an experiment was conducted in Agricultural Research Station of Lorestan University under Khorramabad climatic conditions during 2014-2015. A completely randomized design was used for the experiment with 21 treatments (species-location) with three replications. Phonological and morphological characteristic at growth stage was recorded. Analysis of variance showed significant (p<0.01) differences among species on all traits indicating genetic diversity of the studied species. Cluster analysis and principle component analysis were used to assess the ornamental potential of the studied species and the most important ornamental characteristics i.e. scape length, the diameter of the inflorescence, flower longevity and flower color were evaluated. Biplot were depicted on the basis of both the first and second component that showed 54% of variations. In the biplot and cluster analyses, the species were placed into distinct groups associated with their potential ornamental value. According to the results, Allium iranicum collected from the Alborz-Dizin with large inflorescence (63.28 mm), beautiful flower color (purple) and being green in winter, and Allium oschaninii species collected from Khorasan-Chenaran with great flower longevity (54 d), beautiful form and large scape length (95 cm) were identified as good potent ornamental species.
