Multilocational trials of 16 genotypes of desi and kabuli chickpea (Cicer arietinum L.) were conducted in a number of countries in three seasons at 17 (1981–82), 31 (1982–83), and 22 (1983–84)locations between100_520 latitudes.Combinedanalysisofvarianceforseed yield was done to study the genotype x environment interactions and stability of genotypes. Mean squares for locations, genotypes and genotype X location interactions were significant. Locations and genotype Xlocationinteractionvarianceswere muchhigherthan those for genotypes. Genotypes exhibited relatively. more interaction with winter-sown. locations than with spring-sown locations. Desi types showed more variation than the kabuli types. The mean squares due to desi and kabuli type interactions were higher than
. those for either desi or for kabuli types in two of the three years. Yield performance of the Indian kabuli cultivar L550 was comparable with the best desi cultivar K 850. Seed size did not appearto influence yield performance and stability. Annigeri, Pant G 114, ICCC 8, L 550 and ILC 482 had relatively high yield with good stability. Implications of these observations in breeding for seed yield and wide adaptation are discussed.
