摘　　要：通过对本所两个组合杂种群体植株茎叶和块茎产量的相关规律进行了研究，得到以下结论：单株主茎数与块茎产量呈正相关；相同主茎数的分枝数与块茎产量为正相关；相同主茎数的茎粗与产量呈正相关；株高与块茎产量为负相关；The experimental results showed that:①positive correlation between tuber yield and main stem numbers;②positive correlation between tuber yield and branches with the same stem numbers;③positive relationship between tuber yield and stem thickness;④negative correlation between tuber yield and plant height. and ⑤significantly positive correlation between tuber yield and shoot weight.
