Licorice (Glycyrrhiza glabra L.) is one of the oldest and most important medicinal plants in Fabaceae, used for curing many diseases since 4000 years ago. This study was conducted to evaluate the genetic diversity of 22 different licorice populations based on morphological and yield traits at the research field of the Faculty of Agriculture, Zanjan University, during 2016 to 2018. Morphological and yield traits including plant height and width, leaf length and width, number, length and width of leaflets, number of lateral branches, main stem diameter, aerial parts fresh and dry weight, root fresh and dry weight, root to aerial parts ratio and aerial parts and root yields (per m2) were measured. Canonical discriminant (CDA) and cluster (CA) analyses were used to group the populations. In CDA, the first two canonical variables were significant. The first canonical variable included plant height and width, main stem diameter, leaf length and the number of leaflets, and the second one included aerial parts fresh and dry weight, root fresh and dry weight, root and aerial parts yields. The second canonical variable had the greatest role in population separation and grouping. Canonical variables divided populations into four main groups and confirmed CA clustering results. In general, the results indicated the good potential of canonical discriminant analysis in evaluating the genetic diversity and identifying the index traits in licorice.

Stachys lavandulifolia Vahl. is one of the most important medicinal plants with different applications in pharmaceutical and sanitary industries as well as high distribution in Iran. In order to assess the morphological variation and cutting times in S. lavandulifolia genotypes, an experiment was carried out in a randomized block design with three replicates on 41 genotypes belonging to four regions including Ferydoonshahr, Damaneh, Semirom and Shahrekord. According to analysis of variance, significant differences were observed among all traits studied, while no significant differences were observed among replications. The results of mean comparison revealed that the genotype Damaneh7 in the second cutting time possessed the highest dry weight. Shahrekord 6 in the first cutting time had the highest days to flowering with 100 days. Moreover, Damaneh20 genotype in the third cutting time had the highest essential oil content (3.11%), while the lowest was obtained for Damaneh17 genotype in the first cutting time (0.04%). In general, a significant variation was observed between genotypes and different cutting times. Finally, according to cluster analysis, genotypes were divided into different clusters based on different cutting times.

Rosa damascene Mill. wascollected from west parts of Iran, and cultivated at the experimental field of Research Institute of Forests and Rangelands, using a three replicated randomized complete blocks design. Seven genotypes, were compared for essential oils yield in 2003 and for petal, stamen, and pistil number, in 2003-2004. Genotypes showed significant differences in terms of the measured traits. Comparison of means classified the genotypes in 7, 7 and 7 (in 2003) and 6, 7 and 6 (in 2004) groups, for petal, stamen and pistil number, respectively. Also, essential oils concentration and yield showed genotypic variation. A considerable variation was, therefore, revealed from different analyses in floral parts and essential oils concentration of Rosa damascena Mill. from west parts of Iran. It could then be concluded from the results of different analyses that although the genotypes could be grouped based on geographical origins, concentration and yield of essential oils as the most important product of Rosa damascena Mill., and also some of the related traits, such as floral parts could be used as appropriate selection factors for classification of damask rose genotypes, in order to use in breeding program.

Cuminum cyminum L. is one of the most important and economic medicinal plants with a considerable distribution in different regions of the country. This study was carried out in order to evaluate genetic variation and relationships among traits in 16 populations of Cuminum cyminum L. under field conditions using a completely randomized design with 4 replications. Morphological traits including seed yield, biological yield, plant height, plant weight, the number of umbels per plant, the number of umbelet per umbel, the number of seed per umbel and 1000-seed weight were studied. Results of analysis of variance showed significant differences for all studied traits (p< 0.01) except for number of umbelet per umbel. High values of phenotypic and genotypic coefficients of variation were recorded for most of the traits, indicating high variations for the studied traits. Seed yield varied from 0.75 g per plant in accession of Sirjan to 0.99 g in accession of Birjand. According to the results of correlation coefficients, a high and positive significant correlation was recorded between seed yield per plant and seed number per umbel, the number of umbel per plant, biological yield and plant height. Sixteen populations were classified into four groups based upon cluster analysis. Populations of cluster IV had superiority for seed number per umbel, seed yield, biological yield, and number of umbel per plant compared to other clusters. Consequently, crossing between superior genotypes of different clusters and testing their progeny through breeding and selection programs may result in production of cultivars with desirable agronomic characteristics.

To evaluate 17 Damask rose genotypes regarding their variation for morphological traits, an experiment was conducted at the experimental field of Research Institute of Forests and Rangelands. Analysis of variance, mean comparison and phenotypic correlation analysis were performed. The variance analysis showed significant differences among genotypes for plant height and flower number per branch (P<0.01), number of leaves per branch, leaflet length and thorn density (P<0.05). Also, comparison of means classified the genotypes for the above characteristics. Significant correlations were observed between different traits. A significant (P<0.01) phenotypic correlation (r=0.96) indicated a strong positive relationship between flower yield and number of flower per plant. From the results, a wide range of variation was observed among the genotypes. Morphological characteristics could, therefore, be useful criteria for selection for yield. However, more genotypes, as well as further analyses, including flower quality especially essential oil components are necessary to be considered, in an efficient breeding of Rosa damascena.

Rosa damascenaMill. genotypes werecollected from central parts of Iran, and cultivated at the experimental field of Research Institute of Forests and Rangelands, using a randomized complete blocks design with three replications. Genotypes from six provinces were evaluated for essential oils yield and number of floral parts. Genotypes showed differences in terms of the measured traits. Essential oils concentration and yield showed variation. The most essential oils percentage (0.05%) and yield were observed in Isfahan7 and Yazd1 accessions, respectively, in 2002. Yazd2 and Isfahan6 accessions showed the highest essential oils percentage (0.03%) in 2001, and the most percentage of oils was observed in accession collected from Tehran, in 2003. Also, accession of Yazd1 demonstrated the highest 3-year mean of essential oils percentage and yield. Furthermore, the accessions showed variation for floral parts number. The highest numbers of petals and pistils were observed in accession collected from Tehran Province. Also, Isfahan10 accession showed the highest number of stamens. A considerable variation was, therefore, revealed for floral parts and essential oil content of Rosa damascena genotypes from central parts of Iran. It could then be concluded that the Rosa damascena genotypes differ for essential oils content and this may be applied for classification of Damask rose genotypes. Finally yield of essential oils as the major product of Rosa damascena could be considered as an appropriate selection factor, in order to improve rose varieties.

Rosa damascena from eight rejions in western parts of Iran, were cultivated at the experimental field of Research Institute of Forests and Rangelands, using three replicated randomized complete blocks design. Six genotypes were compared based on different traits including flower yield in 2003 and 2004.The obtained data was performed using ANOVA, (wich mean classification and correlation analyses). Genotypes showed significant differences in terms of the measured traits. Comparison in meaning, classified the genotypes in 4, 2, 3 and 4 groups, based on flower yield, flower weight, dry matter percentage and petal weight to flower weight ratio, respectively in 2003 and in 4, 2, 2 and 5 groups in 2004. It could be concluded from the results of different analyses that although the genotypes could be grouped based on geographical origins, flower yield, flower number and dry matter percentage could be used as appropriate selection factors for classification of damask rose genotypes in western parts of Iran.

In order to study the genetic variation in Rosa damascena Mill., an experiment was conducted at the experimental field of Research Institute of Forests and Rangelands. Eleven genotypes were evaluated, using a randomized complete blocks design with three replications. Flower yield, flower number, single flower weight, plant height, canopy, branch angel, leaf number, spine density and spine length, were analyzed, using analysis of variance, principal components analysis and cluster analysis. The results showed significant differences among genotypes for all of the traits, indicating a considerable genetic variation in germplasm available in Iran. Using principal components analysis, the first three components determined 68.43% of the total variation. According to the cluster analysis, genotypes could be grouped into 3 clusters. Genotypes in cluster 1 averaged well above the overall mean for productivity and the other characteristics.

Rosa damascena Mill. genotypes from different areas of Iran, were cultivated at the experimental field of Research Institute of Forests and Rangelands, using a three replicated randomized complete blocks design. 11 genotypes were compared based on flower yield and morphological characteristics, including plant height, canopy, spine density , spine length, branch angel and leaf number. Evaluation of the obtained data was performed using ANOVA, mean classification and correlation analysis. Genotypes showed significant differences in terms of the measured traits. Comparison of means, classified the genotypes in 3, 4 and 3 groups, based on flower yield, flower number, and average flower weight, respectively. Also, the genotypes were classified in different groups, based on morphological characteristics. The results also indicated that there is a good relationship between some of the measured traits, particularly between yield and number of flowers. It could be concluded from the results of different analyses that although the genotypes could be grouped based on geographical origins, flower yield and number and some of the morphological characteristics could be used as appropriate selection factors for classification of damask rose genotypes, in order to use in breeding programs.
