Keywords:
Chrysanthemum, Evaluation, Genotypes, Dendranthema grandifloraAbstract
Fifteen chrysanthemum genotypes were evaluated in RBD with three replications to select suitable genotypes for cultivation in the plains of Kerala. Significant variations were reported among the genotypes for all the traits. KAU C-7 recorded highest plant spread (47.95 cm), number of primary branches per plant (17.50) and number of leaves per branch (21.50). Earliest flower bud initiation (38.85 days) and 50 % flowering (42.80 days) was recorded in KAU C-1. KAU C-8 took minimum number of days to complete opening of a flower (35.85 days). Greatest flower diameter (8.35 cm), fresh weight (8.07 g) and field life (12.37 days) were observed in Karnool Pink. The longest flower stalk length (26.77 cm) and girth (1.49 cm) was found in KAU C-6. KAU C-4 recorded maximum duration of flowering (104.29 days), greatest number of flowers (96.95) and yield (0.31 kg) per plant. Longest shelf life was recorded in KAU C-7 (4.89 days) and vase life in KAU C-3 (14.48 days). The genotypes KAU C-4 and KAU C-6 can be recommended for both cut and loose flower purposes whereas the genotypes Karnool Pink, KAU C-1, KAU C-7, KAU C-3, KAU C-8 and KAU C-2 are best preferred for loose flower purpose and the genotype Pink Cloud was found ideal for both garden type and loose flower production under warm humid tropical plains of Kerala.Downloads
