Answer: I'm not sure, but it won't affect the fruit color you harvest. You'll only see an affect if you save the seeds from the fruit and plant them - in many years, when they reach bearing age, if they've crossed, the seedlings may have characteristics that show their mixed parentage. One thing to note: red and yellow raspberries have a different growth habit than black raspberries, so take this into consideration if you plan to build a trellis system for them. If you need more info on training, culture, etc., please submit another question, or feel free to search our database. Enjoy!
