GENOTYPE X ENVIRONMENT INTERACTION FOR SEED YIELD IN CHICKPEA

Published on

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 between 100_520 latitudes. Combined analysis of variance for seed 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 Xlocation interaction variances were much higher than
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 appear to 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.
