Evaluation of perennial chrysanthemum cultivars under sub-humid southern plains and Aravali hills of Rajasthan

Abstract

An investigation was carried out with eleven cultivars of Dendrenthema grandiflora L. at Udaipur, Rajasthan to evaluate the cultivars for floral and relative economic parameters. The experiment was laid out in randomized block design with three replications, eleven cultivars by planting 25 plants/ replication and data were recorded on five plants. The data were analyzed by analysis of variance. The maximum plant height (44.21 cm), leaves plant-1 (185.87), plant spread from North-South (27.31 cm) and East-West direction (28.34 cm), sprays plant-1 (16.73), days to end of flowering (145.33 days), flower duration (63.47 days), freshness of flower on the plant under open field (17.53 days), flowers plant-1 (66.86), ten-flower weight (37.30 g), ray floret flower-1 (187.60), spray length (34.56 cm), disc floret flower-1 (209.27), flower weight plant-1 (249.52 g), gross, net returns and B:C ratio were recorded in ‘UHF CRY-77’. Minimum days to first bud initiation (71.07 days), first flower bud opening (84.42 days), complete flower opening (92.8 days) were recorded in ‘Autumn Joy’. The maximum flower diameter (9.68 cm) recorded in cultivar in cv. Garden Beauty, respectively. On the basis of two years pooled data for vegetative, floral and relative economics parameters cv. UHF CRY-77 for cut flowers followed by ‘Jaya’ were found best for cut spray purpose and recommended for sub-humid southern plain and Aravalli hills of Rajasthan.
