| Abstract: | According to three experiments carried out from 1984 to 1986 cluster analysis showed that 11 evaluation indices for resistance to pink bollworm could be classified into five groups; (l)eggs deposited by pink bollworm, (2)entrance holes,invaded by larva insect tunnels and percentage of entrance,(3)number of larvaes, percentage of larval survival and damaged seed (4)number of energence holes,and (5)larvaes/500g of seed cotton, larvaes/seed cotton in 100 bolls and percentage of rotted seed-cotton. |
