Studies on Productivity and Main Characters of Sweet Potato New Variety "Yanshu 5" |
| |
| Abstract: | Yanshu 5" was bred from "Yanchihong (female parent)/Yan 94-1 (male parent)" in 1991.The field experiments conducted in 42 sites showed that the average fresh tuber yield of "Yanshu 5" was 38.85t/hm\+2,being 26.12% more than that of the check variety;the content of carotene,vitamin C,Ca,P and Fe in its fresh tuber was 97.00,167.60,132.10,426.00 and 7.40mg/kg respectively,the total amino acid content in its dry tuber was 3.70%;its daily gain in fresh tuber weight was the highest during the 91st～120th day after planting,being 658.50kg/hm\+2."Yanshu 5" was characterized by early maturity,high resistance to Fusarium oxysporum f.sp.batatas,wide adaptability,exuberant vines and leaves,harmonious growth of above-ground part and underground part. |
