Variability and Correlation Analysis for the Yield and its Traits in Spray Chrysanthemum (Chrysanthemum morifolium Ramat.)

Fifteen genotypes of spray chrysanthemum (Chrysanthemum morifolium Ramat) were evaluated under three date of plantings inside the polyhouse for growth and yield characters during the two consecutive winter seasons of 2003–05. The estimates of genetic parameter of the traits of the fifteen cultivars of spray chrysanthemum undertaken for the study showed maximum magnitude of range in total leaf area per plant with 100% heritability. Number of flowers per plant recorded maximum PCV and GCV values, and also exhibited 100% heritability along with the trait flower yield. The rest of the characters showed above 95% heritability. GA over mean was maximum in the trait branches per plant. Flower yield both in number of flower and in weight was highly correlated with plant growth. Therefore to increase yield the genotypes has to produce more number of branches, total leaf area and plant spread.
