The genetic law of leaf angle in sorghum (Sorghum bicolor (L. ) Moench) and correlation between the leaf angle and other characters on sorghum plant type were studied in 1980-1983. The results showed that the heredity of leaf angle in sorghum were controlled by at least four pairs of alleles which belong to the quantitative characters. The general genetic capacity was between 70 and 90 percent and the restricted genetic capacity was over 80 percent. There were no significant relationship between the heredity of leaf angle and other characters of plant type, but the heredity of leaf angle would take place independently. For the breeding programs on sorghum plant type, the better results of selections of leaf angle can be obtained from early progenies.
