The researchers studied different types of tomatoes to see which ones have the best yield and quality. They grew 37 tomato varieties and measured things like fruit weight and number of fruits per plant. Some tomato types performed better than others, with genotypes 7053, 8105, 8202, 8623, and 8730 standing out. They found that the number of fruits per plant had the highest potential for improvement, followed by maturity days and plant height. This information can help breeders choose the best tomatoes for future growing programs.
