Abstract

In 2001 and 2002, 80 new varieties (strains , cross-pollinated combinations) of Gossypium hirsu-tum L. were tested for their resistibility to Fusarium wilt and 48 were for identification of resistance to Verti-cillium wilt from the Yangze River drainage cotton-growing area.The results showed that 13 varieties expressed disease resistance (account for 16. 25%),50 were tolerant(62. 50%) and 17 susceptible (21. 25%) to Fusarium wilt. 3 varieties(6. 25%) were resistant to Vertillium wilt,41(85. 4%) were tolerant,4(8. 33%) were susceptible. The percentage of resistant varieties tested during this period was higher than that in former years.
