Gram pod borer (Heliothis armigera) (Hub.) resistance in chickpeas uri icon

abstract

  • Heliothis armigera (Hub.) is the major pest of chickpeas (Cicer arietinum L.) throughout the Old World. Since 1976, using an open-field screening technique at ICRISAT Centre in India > 12 000 germplasm accessions were screened, some of which were found to suffer considerably less pest damage than others. Subsequent tests confirmed a difference in susceptibility and found it to be the result of differences in oviposition and larval preference and retention on the plant. Cooperative studies with the Max-Planck Institute for Biochemistry at Munich have shown that the amount of acid exudate on the leaves appears to be a useful criterion for distinguishing relatively resistant, from susceptible, genotypes. ICRISAT plant breeders are presently attempting to intensify this resistance and to combine it with other useful factors, including resistance to fusarium wilt
