In this thesis, the relationships between 17 traits including starch, fibre, culinary quality and agronomic parameters of potato were investigated. In two studies, 12 genotypes were grown at three locations in Ontario and 18 genotypes were grown at four locations in Manitoba, Ontario and New Brunswick. Genotype by environment interactions were significant for fibre and agronomic traits, except bake score and specific gravity. Correlations were found between some, but not all, starch, fibre and agronomic parameters. Several genotypes containing desirable starch, fibre and agronomic profiles with high stability were identified. Although no single genotype was superior in all analyzed traits, certain genotypes excelled in specific attributes. CV96044-3 had the best starch and fibre profile, but low yields compared to other cultivars. Three genotypes, CV96044-3, F04037 and Goldrush, may be useful parents in a breeding program to improve starch and fibre characteristics, producing cultivars containing all desirable traits. / AAFC, Agricultural Bioproducts Innovation Program, BioPotato Network
