abstract: A diallel cross involving nine parent types, representing three diverse agronomically promising cultivars each divided into early, medium and late maturity groups, was used to study the inheritance of leaf area, leaf weight, specific leaf weight, petiole length and petiole weight in pigeonpea (Cajanus cajan (L.) Millsp.). Estimates of genetic parameters suggested a primary effect of additive gene action for all the characteristics studied. However, dominance was also significant for specific leaf weight and petiole weight. Ratios computed using these genetic parameters indicated the presence of partial dominance and unequal distribution of positive and negative alleles in the parents. The correlation between Wr + Vr and Yr was positive and significant only for petiole weight. This together with the position of the parents along the regression line clearly showed that high petiole weight was under the control of recessive genes. In the case of specific leaf weight and petiole length the correlations were non-significant but the position of parents along the regression line gave some indication that large and heavy petioles were controlled by recessive genes.
