The results of a study on correlations between the survival index of cotton to Fusarium wilt and the economical characters: fiber lenght, uniformity index, Micronaire, Pressley, yield, lint percent, seed grade and boll weight, are presented and discussed. The study was carried out in twenty-one experiments envolving the varieties: IAC RM3 (wilt resistant), IAC 12-2 (susceptible) and IAC 13-1 (intermediary in behaviour) and different degrees of intensity of wilt. The resistant variety was the less affected by Fusarium in the above characters, when compared with the other varieties except in the case of seed grade (mean weight of hundred seeds). The survival index showed positive correlation with yield and uniformity index for the three varieties. For a given variety, higher correlations were observed in the case of the characters in which it excelled.
