Improvement of chickpea resistance to wilt and root rot diseases

Jimenez-Diaz R.M., Trapero-Casas A.

Breeding chickpeas for resistance to soil-borne fungi inducing wilt and root rot diseases may be hampered by pathogenic variability in the pathogens, the complex nature of genetics of resistance in the host, and the non availability of suitable resistance screening techniques. Results in our laboratory showed that disease reaction of some resistant kabuli types varies depending upon the pathogen race. Integrating fungicide seed dressings and advancing sowing dates with moderately susceptible cultivars may contribute to control of wilt and root diseases. However, ascochyta blight-resistant cultivars should be used for fall-winter sowings in order to control blight epidemics.
