| Abstract: | Effective utilization of new genes from wild germplasm is important for broadening the genetic base of sugarcane breeding.Aboveground biomass and main characters of root in 11 clones of successive generations of intergeneric hybrid Erianthus arundinaceus×Saccharum spontaneum and their progeny were analyzed.The results showed that the plant height, stalk diameter, single stalk weight and leaf area in the intergeneric hybrids F1 and BC1 were all superior to their parents.Slight increases in weight and activity of root were also found in the hybrid lines.Aboveground biomass was increased distinctively, which displayed a significant correlation with the hybrid vigor of green leaf area.These results provide theoretical bases to improve sugarcane cultivars by utilizing superior genes in both S.spontaneum and E.arundinaceus in introgression breeding program. |
