Evaluation of genetic diversity of Anthemis haussknechtii and Anthemis altissima populations through agro-morphological characteristics
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 7, Issue 1
Abstract
Anthemis altissima L. and Anthemis haussknechtii are two valuable medicinal plants that antioxidant and antibacterial activity of their essential oil is reported. Most of the medicinal plants are harvested from wild resources. Introducing high yielding varieties could reduce pressure on natural resources and prevent genetic loss. Genetic diversity is the foundation of the improvement of crops. The goal of this investigation is to determine the extent of variability existing among 21 A. haussknechtii and 5 A. altissima populations through agro-morphological characteristics. A total of 8 agro-morphological traits namely, height, flower number, fresh weight, dry weight, percentage of dry matter, plant canopy, GDD(Growing Degree Day) to flowering and GDD to maturity were recorded. Although 5 population of A. altissima were collected from 5 different provinces result of ANOVA and Duncan’s Multiple Range Test showed low diversity among these populations. A. altissima Populations had larger plants with more flowers. According to principal component analysis, the two first components explained 82% of total variability of the data in A. haussknechtii. Results of correlation analysis showed the significant correlations among most of the characters. The first component including plant canopy, height, fresh and dry weight, explained 67% of total variation. Populations of A. haussknechtii were classified into 4 clusters through hierarchical cluster analysis. Based on the result it was recommended that crosses could be made between cluster 1 and cluster 2 to get early matured variety with high flower yield. Wide range of variations among populations suggests good potential for selection in breeding programs.
