Popis: Although tomato is the leading vegetable crop in Kenya, not much work has been done to develop improved tomato varieties with farmer preferred and market demanded traits. This study aims to characterize ten tomato genotypes for morphological and agronomic traits and to identify potential parental lines for use in the breeding program. The experiments were conducted in Kenya during the 2017 long and short rain seasons. Trials were laid out in a randomized complete block design with three replicates. Study materials were AVTO1429, AVTO1424, AVTO1314 from World Vegetable Center, four commercial varieties namely; Riogrande, Cal J, Roma VF, UC82 and three farmer selections namely; Valoria, Danny and Eden select. Genotype effects, genotype x environment interactions and location effects for days to flowering, plant height, maturity, fruit yield and related traits were highly significant (P
