Abstract

Matricaria recutita is one of the most important cultivated medicinal herbs, particularly in Europe. This study was carried out in order to evaluate morphological, phenological and essential oil variation on fourteen genotypes derived from Esfahan, Arak, Ahwaz, Ardabil, Kerman, Tehran, Shiraz regions. Fourteen genotypes cultivated in complete randomized block design with three replications in Fozveh research farm, Esfahan agriculture research center. Fifteen characters of morphological, phenological and essential oil were measured. Analysis of variance of traits showed significant differences among genotypes for all character except for fresh weight per flower. Coefficient of genotypic and phenotypic variation of number of flower per plant, fresh and dry weight plant and essential oil was higher than other studied character. The highest and the lowest heritability broad sense was belong to number of days to 50 percent flowering and number of days to stem, respectively. Essential oil varied from 0.24% in Kerman genotype to 0.57% in genotype of Shiraz. Cluster analysis divided the genotypes into 6 cluster, each of which having 5, 4, 2, 1, 1 and 1 genotypes. The clustering pattern of the genotypes revealed that geographic diversity was not related to agronomic diversity. These results could be useful in choosing genotypes for intercrossing to develop improved cultivars.
