Abstract
A study was undertaken to determine association between different quantitative and qualitative traits of 10 genotypes of crossandra collected from various sources. The correlation analysis revealed that, all vegetative parameters (plant height, plant spread, number of branches, leaf area) and flowering parameters (number of flowers per spike, number of spikes per plant and spike length) showed significant and positive correlation with flower yield per plant. However, the number of days for spike initiation and number of days for first harvest showed significant negative correlation with flower yield per plant.
All the quality attributes like flower diameter, corolla length, weight of 100 flowers and shelf life showed a significant and positive correlation with each other except corolla length with shelf life, which showed a non-significant correlation coefficient. These traits may serve as effective selection parameters for breeding in Crossandra for improvement of the yield.

Conclusion
The correlation analysis revealed that, flower yield per plant showed significant and positive correlation with plant spread, number of spikes per plant, leaf area, plant height, spike length, number of flowers per spike, number of branches, corolla length, weight of 100 flowers. However, the number of days for spike initiation and number of days for first harvest showed significant negative correlation with flower yield per plant.
