Abstract
Eight genotypes of chickpea (NCS-0609, CH38/00, DCK-110-1, NCS-0530, CC121/00, NCS-0608, DCK-112-2 and CM-2000) developed by different institutes of Pakistan, were evaluated under eight different locations for various agronomic traits against the prevalent biotic (pests and diseases) and abiotic (drought) stresses in the area. Grain yield of two genotypes (CH38/00 and CC121/00) from Nuclear Institute of Agricultural and Biology, Faisalabad, have shown significantly higher yield than check at National Agricultural Research Centre, Islamabad as well as at all locations. The interaction between the genotypes and environment (G x E) was used as an index to determine the yield stability of genotypes under all different eight locations during 2007-08. Both predictable and unpredictable portion of variation were found to be significant indicating equal importance in determining the stability of grain yield. The two genotypes i.e. CC121/00 and CH38/00 produced average grain yield 1637 Kg ha-1 and 1386 Kg ha-1 respectively at all locations than the check (1152 Kg ha-1 ) and thus were the most adapted cultivars in the whole set of environments/locations during 2007-08. The objective of the trial in question was to find out the adaptability range of test genotypes.
