Root-knot Nematode Tolerance And Seeding Disease in Acala Cotton Lines

R.H. Garber, S.R. Oakley and J.E. DeVay


California Planting Cotton Seed Distributors has strived for many years to develop cotton (Gossypium hirsutum L.) varieties with higher yields and tolerances to cotton diseases. This has been a cooperative effort with the United States Department of Agriculture, the University of California, and San Joaquin Valley cotton growers, involving both greenhouse and field trials. Most work in developing new California Acalas has centered on developing varieties with higher lint yields that meet the state's quality standards. These varieties usually included high tolerances to verticillium wilt. A need for Acala varieties with higher tolerances to the pathogens involved in the seedling disease complex, the fusarium wilt/root-knot nematode complex, and the verticillium wilt has been recognized.
