Abstract Highlights

Mexico is considered the domestication center of tomato (Lycopersicon esculentum Mill.). However, there is scarce information available to allow the use of native forms of this species. The objective of this study was to evaluate some characteristics of agronomic interest of seven genotypes from the states of Guerrero and Puebla, grown hydroponically in a greenhouse, and compare them with a commercial “cherry” tomato hybrid (H-790). Days to flowering and days to maturity in the first cluster, plant height, stem diameter, fruit length and width, number of loculi and fruit weight were assessed. Number of fruits and yield in six clusters were also assessed. In the characteristics days to flowering and days to maturity in the first cluster, plant height, stem diameter, fruit length and width, number of loculi, fruit weight and yield, at least one native genotype exceeded (P ≤ 0.05) the control (H-790). In number of fruits in six clusters, the JCPRV-43 and JCPRV-05 genotypes were similar (P ≤ 0.05) to the control (43.9). Stem diameter was the only characteristic where the control (18.1 mm) was better (P ≤ 0.05) compared to the native genotypes evaluated. It is concluded that owing to their agronomic characteristics, most of the assessed native genotypes can be cultivated as “cherry” tomatoes, and some of them could be utilized as a source of germplasm in breeding programs of this species.
