Correlations among economic traits - time to flower, time to maturity, seeds/pod, 1000-grain weight, grain yield, dry matter production, and harvest index - were studied in 19 promising Indian cultivars. Large variation was recorded for all these characters except for time to maturity. Seed size had a highly significant negative correlation with seeds/pod (r=-0.79). A significant negative correlation between time to flower and 1000-grain weight (r=-0.68) indicates that most of the bold-seeded Indian lentils are early flowering. Longer periods of flowering and maturity produced more dry matter. The traits of seeds/pod and total dry matter increased grain yield the most. Harvest index was negatively correlated with earliness, while a harvest index of 40-50% was best for high yield. Total dry matter was also significantly and positively correlated with grain yield
