Abstract:In 2003, 15 new materials from the Changjiang River valley cotton-growing area were identified for resistance to pink bollworm. Results showed that 8 (53.33% ) materials were highly resistant to pectinopho-ra gossypiella , 4 (26.67%) were resistant, 3 (20.00%) were moderately resistant. Fifty-five new materials were tested for their resistance to Fusarium wilt and 59 were for identification of resistance to Verticillium wilt. The results showed that 27 materials expressed disease resistance (account for 49.09%), 26 were tolerant (47.27%) and 2 susceptible (3.64%) to Fusarium wilt. Eight materials (13.56%) were resistant to Verticillium wilt, 43 (72.88%) were tolerant, 8 (13.56%) were susceptible.
Keywords:Cotton  New variety  Disease resistance  Insect resistance  Fusarium wilt  Verticillium wilt  Pectinophora gossypiella
