Two sugarcane varieties as control and sixty–eight combinations from Yunrui 2013 series were used as materials to study the heredity of nine major characters. The results indicated that the parents of Yunrui and their combination had extremely significant effects on offspring; the hereditary capacity of the parents showed significant different in 5 characters of Brix, height, diameter, the number of effective clusters and stem weight, while the hereditary capacity of the 5 characters were more than 50% in parents and their combinations; among these parents, 21 female parents and 17 male parents had excellent general combining ability, which was better than the two control varieties, they were the female parents of YR09–928, YR05–628, YR10–559, YR10–648, YR09–525 etc and the male parents of YR05–458, YR06–4337, YR05–785, YR05–160 etc; many combinations showed excellent special combining ability, they included 28 combinations with high yield and high sugar content of YR09–928×YR05–285, YR05–628×YR06–4337, YR10–559×YR05–271, YR09–772×YR05–207 and YR10–648×YR05–785, High yield combinations of YR07–3082×YR05–407, YR08–954×YR05–207, YR10–896×YR05–207, YR06–4679×YR10–915, YR10–291×YR08–1287 and high sugar content combinations of YR09–754×YR05–285 and YR05–785×YR07–1226.
