Low temperature and a relatively long incubation period are required for sexual reproduction in most Ascomycetes. Khune, The Coelomycetes of India: Production of chickpea contributed to agricultural sustainability through N 2 -fixation and by being a rotation crop. Later, they develop a brown margin with a white center and split longitudinally. Localization of resistance genes for fusarium wilt races 4 and 5.

Antibiosis mechanism of resistance to pod borer, Helicoverpa armigera in wild relatives of chickpea. Genetic diversity studies in a crop are important for various aspects such as management of genetic resources, identification of duplicate accessions in the germplasm ascochhyta in applied breeding programs. Marker Assisted Selection MAS can be applied effectively using DNA markers linked to resistance genes for accelerating disease resistance breeding programs.
