| Abstract: | A comprehensive appraisement of 10 maize varieties was made by grey relational cluster. The 10 varieties were clustered into three types at the level of A=0.85. Suwanl variety ranked the first in the relational degree among all the testes, indicating optimum overall characteristics. The varieties Tainan No.17, Xiachenyunyou No.78 and Tainong No.351 were clustered into the second or medium type; the rest six varieties the third or poor type, of which the variety NS1 was the poorest. |
