ABSTRACT
The investigation was carried out with twenty chrysanthemum genotypes at Horticultural Research Centre (HRC) of SVPUAT, Meerut, UP during 2016-17 to study the genetic diversity among the genotypes. The maximum days to flower bud initiation (43.53 days) and days to flowering (69.53 days) was observed in the cultivar of Ajay while cultivar White Star produced larger size flower (9.97 cm). The maximum flowering duration (57.53 days) was observed with the cultivar of Haldighati and maximum plant height at flower bud initiation stage (28.27 cm) and plant height at full bloom (57.53 cm) was observed with the cultivar of Sunny. Cultivar of Basanthi produced maximum number of primary branches (7.93), plant spread (70.73 cm) and maximum number of flowers (218.67). D2 analysis grouped among the genotypes into five clusters showing the existence of considerable amount of variation among the genotypes. Cluster pattern revealed that, cluster V had largest number of 6 cultivars, followed by cluster III (5 cultivars), cluster II (4 cultivars), cluster IV (3 cultivars) and cluster I had only (2 cultivars). Highest intra-cluster distances were found for cluster III (D2 =2.117) whereas, highest inter-cluster distance was observed between clusters V and IV (D2 4.402). The cluster means revealed the best cluster for various growths and flowering traits depending upon the aim of breeding programme and potential line can be selected from different clusters as parents.
Key words: Chrysanthemum, Genetic diversity, Morphological characterization, Cultivar identification.
