Title : Comparative evaluation of cherry-type tomato breeding lines for hydroponic greenhouse production

Abstract:

California is a leader in U.S. greenhouse tomato production, with hydroponic systems offering the potential for higher yields and enhanced sustainability. Cherry-type tomatoes, known for their rich flavor, are targeted in breeding programs for traits such as increased secondary metabolites and resistance to plant virus pathogens. However, challenges like blossom end rot and fruit cracking highlight the need for further genetic research and breeding strategies. This study evaluates five selected cherry-type tomato varieties grown in greenhouse hydroponic systems, assessing fruit qualities (e.g., cracking, blossom end rot, color, yield), plant mortality, and plant health indicators like NDVI and CCI. The study aims to evaluate the adaptability of these germplasms to hydroponic production systems, providing insights for future breeding programs. Preliminary data show significant differences among tomato lines, suggesting potential for breeding based on key traits impacting fruit marketability. The results contribute to enhancing tomato production and fruit quality in Southern California's conventional greenhouse hydroponic systems.
