The Q&A Archives: Cross Polination of Yellow and Italian Tomatoes

Question: We had purchased 4 yellow (less acid) tomato plants, in the next two rows of the garden we planted 12 italian tomato plants. Now the question...... our italian tomato plants have produced ALL orange fruit. Could this be due to cross polination? Or is there a type of italian tomato like this-normal in size and taste as red?

Answer: The tomato plants you purchased this year could not affect each other's fruit. (Cross pollination only affects the next generation to be grown from the seeds of this year's fruit.) Apparently there is indeed an orange Italian variety because you are growing it. There are new tomato varieties being introduced every year, and some of the tomatoes may look more orange than deep red -- it depends to some extent on personal definitions of color. You might ask your supplier if they have a record of which paste tomatoes they sold; it's always possible a tag got switched in the spring sales rush. Enjoy!
