| 摘 要： | 以华南205(SC205)为对照品种，研究华南5号(SC5)、华南6号(SC6)、华南7号(SC7)、华南8号(SC8)和华南9号(SC9)的生长发育及产量性状。结果表明，在整个生长过程中，SC7生长最快，其次为SC6，最慢的是SC9；SC8、SC5、SC7和SC6的产量分别比SC205(CK)增产24.71%、20.63%、10.71%和6.76%；而SC9的产量比SC205(CK)减产10.14%； SC8淀粉含量最高, 其次为SC5，分别为30.05%和29.80%，分别比SC205(CK)高1.9

| Abstract: | Six cassava varieties, South China 5 (SC5), South China 6 (SC6), South China 7 (SC7), South China 8 (SC8) and South China 9 (SC9), were observed in terms of growth and yield with cultivar South China205 (SC205) as the control. The results showed that the SC7 was highest in growth rate, followed by the SC6, with the SC9 being the slowest during the whole stage of growth and development. The varieties SC8, SC5, SC7 and SC6 outyielded the control SC205 in terms of fresh tuber by 24.71%, 20.63%, 10.71% and 6.76%, respectively, but the SC9 yielded lower than the control by 10.14%. As to starch content, the SC8 was the highest (30.05%), followed by the SC5 (29.80%), and these two varieties were 1.97% and 1.72 % higher in starch content than the control SC205, respectively. According to the evaluation of comprehensive traits, the best variety was the SC8, followed by the SC5, SC7 and SC6, and the poorest were SC205 (CK) and SC9. |
