Genotype and environment effect on canning quality of Kabuli chickpea. Can. J. Plant Sci. 82: 267-272. Chickpea (Cicer arietinum) has become an important pulse crop in Saskatchewan where both the large-seeded (kabuli) and small-seeded (desi) market classes are grown. In North America, kabuli chickpea is mainly used for canning and in salad bars. Both the genotype and the environment affect the canning quality. This study was conducted to determine the effect of genotype, environment and genotype × environment interactions on canning quality traits of three kabuli chickpea cultivars. The three cultivars were grown in 17 environments in Saskatchewan and Alberta during 1996, 1997 and 1998. The genotype, environment and genotype × environment interactions were significant for most canning quality traits. Significant genotype × environment interactions suggest that chickpea cultivars did not perform consistently relative to each other in different environments. This suggests that breeders must give due consideration to quality traits of both the dry and the canned product during the selection process. The results make apparent the magnitude of genotype × environment interactions that chickpea breeders must confront and indicate that extensive testing of chickpea for canning quality traits over different environments is required. Or, le génotype et l'environnement modifient ses propriétés de conservation. La présente étude devait établir l'incidence du génotype, de l'environnement et des interactions génotype × environnement sur les caractéristiques de trois cultivars de pois chiche kabuli au niveau de la qualité des conserves. Les trois variétés ont été cultivées dans 17 milieux différents en Saskatchewan et en Alberta, en 1996, 1997 et 1998. Le génotype, l'environnement et les interactions génotype × environnement affectent sensiblement la plupart des propriétés d'appertisation. Les importantes interactions entre le génotype et le milieu donnent à penser que la performance du pois chiche varie d'un cultivar à l'autre, selon l'environnement. On en conclut que les phytogénéticiens devraient sérieusement songer à tenir compte des paramètres qualitatifs du produit sec et des conserves dans leurs travaux de sélection. Les résultats révèlent l'ampleur des interactions génotype × environnement avec lesquelles les obtenteurs doivent composer et indiquent qu'il faut procéder à d'importants essais sur les paramètres qualitatifs du pois chiche de conservation dans différents milieux.

In Saskatchewan, chickpea is increasingly becoming an important crop. In the year 2000, 280 000 ha were grown to the crop and the area grown to chickpea is projected to continue to increase. Both the large-seeded (kabuli ) and the small-seeded (desi) classes are grown in Saskatchewan. The kabuli type...
