Extent of genetic variation for growth and floral characters in chrysanthemum cultivars under Assam condition

Eleven cultivars of spray chrysanthemum were planted in open condition. The estimates of GCV's and their corresponding PCV's clearly revealed maximum genetic variation for leaf number followed by number of primary branches, stem thickness and plant height among growth characters. In case of flower characters, the estimates of GCV's and their corresponding PCV's clearly revealed maximum genetic variation for number of flowers/plant, followed by number of ray florets and dry weight, respectively. These three characters exhibited maximum genetic variation and were least affected by environment. Number of flowers/plant, which exhibited maximum genetic variation also exhibited highest GA percentage.
