A study on tomato plants found that there is a lot of variation in traits like fruit yield and plant height among different types of tomatoes. The researchers looked at 36 different tomato genotypes and found significant differences in all 10 traits they studied. They discovered that traits like number of fruits per plant and fruit yield per plant showed high variability and heritability, meaning they can be useful in breeding programs to create better tomato varieties. The study suggests that certain traits like days to flowering and fruit maturity can be targeted for improving tomato crops.
