Abstract

Sixty seven genotypes derived from twenty three cross combinations were screened for their reaction to the most virulent red rot pathotype Cf 08 from CoJ 84 and most prevalent pathotype Cf 03 from CoJ 64 under Punjab conditions and North-west zone. A total of thirty genotypes belonging to eleven cross combination were found to have moderately resistant reaction to both the pathotypes. Three cross combination namely; CoS 96869 GC, CoS 92263 and Co 1148 GC were found to be promising, yielding higher number of resistant clones as compared to other cross combinations. Overall, the various cross combinations were found to give 65.70 and 49.25 per cent moderately resistant progenies to red rot pathotypes Cf 03 and Cf 08, respectively which indicated that the choice of parents is fairly appropriate for the generation of elite clones possessing tolerance to red rot disease.
