Abstract
A major limitation in breeding for insect resistance is the escape of genotypes. Recurrent selection schemes for intrapopulation improvement based on alternate evaluation of first generation families (half-sib or full-sib or selfed) and second generation families developed throug h selfing or crossing in them, are presented. These enable selection o f genotypes over two generations which should help in minimising the e scapes and increasing the genetic progress for insect resistance.
