Abstract

Four characters, namely plant height, head diameter, leaf length and leaf widths showed similar pattern of association in different samples of parental base population. The full-sib and half-sib families populations showed different pattern of association between traits. Some associations between traits such as leaf length and leaf width and between number of leaves/plant and plant height in half-Sib families population and between leaf length and leaf width, plant height and head diameter in full-sib families population remain unchanged whereas some other correlations such as between 100-seed weight and leaf width disappeared in half-sib as well as full-sib populations. Some new correlations such as seed yield/plant and head diameter and days to first flowering and days to maturity appeared in the full-sib and half-sib progeny populations.
