STUDY ON GENETIC DIVERSITY IN GENOTYPES OF TAREE IRANI (ALLIUM AMPELOPRASUM SSP. PERSICUM) USING MORPHOLOGICAL CHARACTERS

Genetic diversity of 38 Taree Irani (Allium ampeloprasum ssp. persicum) genotypes collected from different parts of Iran were investigated during 1999-2000 at the Horticultural Center, Faculty of Agriculture, The University of Tehran. using morphological characters. Based on descriptors, 45 characters were studied. According to the cluster analysis four different groups, each containing 1,3,3 and 31 genotypes were determined. Having special characters such as early flowering and different flower organs color, Ahvas 19 genotype felt in the 1 st. group individually. Zabol 24, Fars 40 and Hamedan 49 genotypes felt in the 2nd. group and Azarbaijan Gharbi 27, Hamedan 47 and Hamedan 50 in the 3rd. group. The remaining 31 genotypes felt in the 4th group. Genotypes of this group were late flowering and compared with the 1 st. group had different flower organs color. Second and 3rd. groups were intermediate in characters. Based on clustering yield components, of different genotyps, 11 superior genotypes, all from the 4th. group, were identified. There was also positive correlation between date of flowering and dominant flower organs color. No significant correlation was found between origin and genetic distance of genotypes.
