ABSTRACT

The root-knot nematode is the most widely distributed nematode that affects cotton. Currently, there are no nematode resistant varieties available to cotton producers in the southern cotton belt. In 2002, twenty-four entries from the regional breeder strain test were evaluated for root-knot resistance at the Red River Research Station in Bossier City, Louisiana. None of the entries were as resistant to root-knot nematodes as the check varieties Acala Nemx and Stoneville LA 887. Four entries, Acala Nemx, Stoneville LA 887, Ark 9101-97-10 and Ark 9111-57-20, produced significantly lower root gall ratings than other entries.
