Abstract


Twenty genotypes of chrysanthemum were evaluated with an aim toidentify suitable genotype based on different characters under hillzone of Karnataka. The results revealed that among the differentgenotypes the maximum plant height was recorded in the genotypeACC 1 (37.11 cm) while genotype Sharadmala recorded minimumplant height (14.43 cm). The maximum stem girth was recorded in thegenotype Star Pink (4.72 mm) while minimum recorded in the genotypeRed (2.53 mm). The maximum number of leaves and leaf area wasobtained from genotype Chandini (251.96 and 9913.82 cm2)respectively. Genotype Marigold (Kolar local) took minimum numberof days (80.25) for appearance of first flower and flowered formaximum duration (130.67 days) whereas, the genotypes Sharadmalatook maximum number of days (149.08) for appearance of first flowerand flowered for minimum duration (45.78 days). The genotypeMarigold produced maximum flower yield (536.86 g/plant) whileminimum recorded in the genotype Red (84.32 g/plant). The variationin flowering characteristics among the genotypes was attributed togenetic makeup.
