The number and percentage of nodes bearing two pods in 'double-podded' cultivars of chickpeas growth in northern India (at Hissar) and peninsular India (at Hyderabad) were compared. At Hissar 11% of the pod-bearing nodes were double-podded; at Hyderabad 28% were double-podded on early-sown and 49% on late-sown plants. In all cases the number of double-podded nodes per plant was similar, but different numbers of single- podded nodes per plant were formed, depending on the length of the growing season. At Hyderabad the percentage of double-podded nodes was not significantly affected by population-density nor by shading the plants throughout the reproductive phase. Partial defoliation of the plants reduced the percentage of double-podded nodes, as did the removal of all flowers from the plants for the first two to four weeks of the reproductive phase. The conversion of 'double-podded' plants to 'single-podded' plants by cutting off one of the flowers at every double-flowered node had no effect on yield at a location in the Himalayas where the double-podded character was poorly expressed, but at Hyderabad the yield of the 'single-podded' plants was significantly reduced compared with the 'double-podded' controls. The results indicate that the double-podded character can confer an advantage in yield of about 6 to 11% under conditions in which the character is well-expressed.
