International Screening
Chickpea International Ascochyta Blight Nursery (CIABN)
The CIABN was initiated during 1978/79 with the objectives of identifying
sources of resistance/tolerance to ascochyta blight in different countries of the
region, identifying sources of resistance across locations and seasons, and collecting
information on the existence of races of the pathogen. The nursery was
continued during the 1979/80 and 1980/81 seasons.
The entries in the CIABN mainly consisted of those found resistant at
ICARDA and some in propagator screening at ICRISAT. A few of the lines
reported resistant by earlier workers for which seed was available were also
included. The nursery comprised 40, 50 and 40 resistant/tolerant entries during
1978/79, 1979/80 and 1980/81, respectively. The entries included in the nurs­
