Abstract:

Correlation and path analysis were carried out in 16 genotypes of chrysanthemum (Dendranthema grandiflora Tzvelev) for different yield attributing traits. Among twelve different parameters to differentiate the contribution made by each parameter in the final flower yield. The results revealed that the genotypic correlations were higher than the phenotypic correlations for the characters studied, indicating the high heritable nature of the characters. The genotypic correlation of flower yield per plant was showed highly significant and positive correlation with leaf area (0.885), number of leaves per plant (0.714), number of flowers per plant (0.677), duration of flowering (0.640), plant height (0.609), number of primary branches per plant (0.575), stem girth (0.531), flower weight (0.542) and number of secondary branches per plant (0.441). While, non-significantly positive correlation for flower yield per plant was observed with internodal length (0.186) and flower diameter (0.268). Since these associations are in desirable direction and selection of these traits may ultimately improve the yield. Path coefficient result revealed that the number of flowers per plant (1.831), flower weight (0.701), internodal length (0.296), number of secondary branches per plant (0.168), flower diameter (0.162), duration of flowering (0.155) and leaf area (0.088) exhibited maximum positively direct effect on flower yield per plant. Flower yield per plant had negatively direct effect from plant height (-0.136), stem girth (-0.202), number of primary branches per plant (-0.218), number of leaves per plant (-0.919) at the genotypic level. Thus, these characters have maximum contribution towards the flowers yield per plant.
