A study was made of leaf area and distribution of dry matter in inbreds of maize and their hybrid under field conditions. The leaf area of the cob bearing leaf in the inbred parents was about 70 to 75% of that of the hybrid, but above the cob it was 54 and 72%. However, the yield of these parents was 48 and 36% of the hybrid. It appears that the dry matter production and its distribution after anthesis is largely responsible for yield difference. These results are discussed in relation to metabolic aspects of grain development.
