Genetic Diversity of Chrysanthemum from Vietnam and Malaysia based on Correlation Coefficients and Principle Components Analysis
Main Article Content
Abstract
The purpose of this study was to study on growth, yield components, correlation coefficients and principle components analysis of 14 chrysanthemums. This research is during October 2022 to February 2023 at Mahidol University, Kanchanaburi Campus. The results showed that ML09 had the highest in plant height and stalk length of 74.0 cm and 14.92 cm, respectively. ML06 had the highest in number of leaves, flower diameter and flower width of 25.6 leaves, 8.65 cm, and 4.79 cm, respectively. The petals color is various. The plant height of the chrysanthemum was negatively correlated with the number of flower buds (r = -0.62). Flower diameter was positively correlated with flower width (r = 0.94). The principal component analysis according to 6 characteristics : plant height, leaf number per plant, flower bud number, flower stalk length, flower diameter, flower width found that PC1 is described as a total variance of 40.94 %, PC2 is described as a total variance of 28.76 %.
