To me, that is a short cross that will give you a general idea if there is genetic potential in that cross. And then you can follow up with a long cross if you like what you see or do sibling crosses of the best ones so that you can realize the goal you set when you made the cross. To fully explore the potential of any given tetraploid cross, you would need to plant about 10,000 seeds....most people do not have space for that. So for beginners, it is important to do many short crosses in order to find out what the good parents are in the plants that you are using. And how many seeds you plant would depend on your space for planting and your willingness and physical ability to dig up and dispose of the rejects.
