    Abstract:

    In order to investigate whether fuzzy imported from Australia is imported in Chinese sugarcane breeding, a family trial by using12 families generated from fuzzy imported from Australia and 15 families from domestic fuzzy was conducted. The variance analysis, heritability, general combining ability (GCA) and special combining ability (SCA) of 6 important traits, including cane yield, sugar yield, plant height, stalk diameter, amount of stalks and brix were evaluated. The results indicated that: (1) no significant at more of the major traits among domestic families was detected, and the heritability was low; By contrast, the significant differences were observed among Australia families, and their heritability were much higher; (2) the GCA and SCA of sugar yield, cane yield, height, stalk and brix of Australia families were higher than domestic families for both plant and ratoon crops, but the GCA and SCA of diameter was lower than the domestic, 9 in planting stage and 10 in ratooning stage out of 12 families performed negative SCA,respectively , and most of the progenies performed thin stalks; (3) Australia families outperformed on cane and sugar yields, with an inferior of thin stalk which is not suitable for the cultivation system in China, so they were not recommended for commercial breeding in China;(4) the imported fuzzy could be utilized potentially in breeding via hybridization with domestic parental clones, thus being helpful in enlarging the Chinese sugarcane gene pool and also breeding for elite varieties.
