Abstract

A study was conducted to evaluate the performance of ten chrysanthemum cultivars for better post harvest quality under open field condition at University of Agricultural Sceinces, Bangalore. Flowers were harvested at fully open stage or nearly so. The results showed that the maximum stalk girth (0.32 cm) was recorded in Cv. Cassa and the maximum flower diameter (8.14 cm) was recorded in cv. Ravikiran, Cultivar Cassa recorded the maximum flower weight (3.59 g). Maximum number of ray florets were recorded by cv. Nilima (253.2). The maximum length of ray florets were recorded in cv. Ravikiran (3.96 cm). Maximum fresh weight, final weight and water loss (88.33, 40.63 and 47.67g respectively) from the spray type flowers were recorded in cv. Arka Swarna. Longer vase life of 16 days was also recorded in cv. Arka Swarna. Based on the performance studies it was observed that Arka Swarna, Ravikiran, Red gold, Nilima and Arka Ravi performed better post harvest quality and may be selected for cut flower production.

Abstract

Studies on genetic variability, heritability and genetic advance were carried out among ten genotypes of chrysanthemum for characters to identify elite genotypes to be used in breeding programme. The results showed high phenotypic and genotypic co-efficient of variation for traits like number of suckers per plant (GCV=90.13; PCV=95.67) and flower disc diameter (GCV=63.19; PCV=66.76). High heritability values were obtained for all the characterister except number of sprays per plant and plant spread. In high heritability estimate coupled with high genetic advance as per cent of mean was observed for number of suckers per plant (174.91), flower disc diameter (123.23) and number of flowers per plant (114.81). It was observed that heritable variability in the breeding materials characters like number of suckers per plant, flower disc diameter, number of flowers per plant, flower weight, yield per plant and number of ray florets could be exploited for improvement through crop breeding programme.
