Description Forty groundnut advanced breeding lines along with susceptible checks JL-24, J-11 and TMV-2
were used for collar rot (Aspergillus niger) and stem rot (Sclerotium rolfsii) disease screening.
Based on the per cent number of plants affected by the collar rot pathogen, the advanced
breeding lines were categorized into four groups. The lines present in group I (Resistant) having
< 15% incidence, group II (Moderately resistant) having 15.1 to 30%, group III (Susceptible)
having 30.1 to 45 % and group IV (Highly susceptible) having > 45% incidence. Similarly
among 40 breeding lines only three lines (ICGV86699, ICGV91114 and ICGV 89280) have
shown stem rot disease reaction below 3 (up to 25 % plants were symptomatic) and considered to
be moderately resistant to stem rot pathogen. The advanced breeding line ICGV99058 has
recorded a disease reaction of 5 scale (> 50 % of the plants symptomatic) equal to the
susceptible checks which is considered to be highly susceptible to stem rot pathogen.
