Evaluation of newly developed genotypes of chrysanthemum (Dendranthema grandiflora Tzvelev) for cut flower production

Abstract

An experiment on evaluation of newly evolved genotypes of chrysanthemum (Dendranthema grandiflora Tzvelev) for loose flower production was conducted to evaluate 23 genotypes of chrysanthemum including ‘Surf’ as a standard check for the experiment. Among all the genotypes, ‘UHFSChr 132’ bearing purple (75 A) colour and double type large flower (5.01 cm diameter). This genotype is having profuse flowering habit (435.93 number of flowers per plant) with average weight of 702.54 g of flowers per plant and yield is about 6322.83 g/m2. It has longer flowering duration (38.53 days) with shelf life of 3.27 days. Whereas the control (Surf) exhibited flower diameter of 6.40 cm, flower weight per plant (700.63 g), yield 6305.700g/m2 with maximum shelf life of 4.47 days. It was followed by ‘UHFSChr 117’ (bearing flowers with yellow (12 A) colour, double type flower, diameter (3.51 cm), number of flowers per plant (408.33), weight of flowers per plant (657.11 g), yield/m2 (5913.990 g), duration of flowering (26.6 days) shelf life of 4.6 days), ‘UHFSChr 122’ (bearing greyed orange (163 B) coloured semi-double type flower, diameter (3.48 cm), number of flowers per plant (350.47), weight of flowers per plant (636.64 g), yield/m2 (5729.790g), flowering duration (114.13 days) with shelf life of 3 days) and ‘UHFSChr 113’ (bearing greyed orange (171 A) coloured intermediate incurve type of flower (5.02 cm diameter), number of flowers per plant (235.67), weight of flowers per plant (486.94 g), yield/m2 (4382.460 g), duration of flowering (117.73 days), shelf life of 2 days), were observed to be the best genotypes for the loose flower production.
