Viabilidade da seleção de variedades de algodão resistentes a nematôides
Viability of breeding cotton for nematode resistance
C. A. Menezes Ferraz
SUMMARY
Results from cotton trials planted on soil highly infested with the root-knot nematode showed that out of 250 varieties tested, 13 were very tolerant. Among these five were the local selections 1.A.C.8 ( 51/598), I.A.C.9, I.A.C.10, I.A.C.II and I.A.C.I2. Individual plant selection made within the tolerant varieties is expected to increase the tolerance of the progenies to root-lknot nematode attack.
It is pointed out that it is possible to reduce or eliminate yield losses due to the root-knot nematode attack hy growing tolerant or resistant varieties on infested soils.
