| Abstract: | Objective] To screen the new variety of high-starch sweet potato.Method] Eight new varieties of starch potatoes were selected for comparative test.The agronomic characters and starch content were analyzed.Method] Fresh yield of potato line 47208 and its starch yield were both higher than those of the control Xushu 22.Among them, Fresh yield of potato was 12.64% higher than that of control; starch yield was 20.35% higher than that of control.Therefore, line 47208 had the maximum starch yield and good shape, which could be used as alternative va-riety for further comparative test and verification.Conclusion] This research provides scientific basis for the extension of new high-starch potato line. |
