The high yield seeds are created by cross pollinating certain varieties. When the high yield seeds are planted, the new seeds should be eaten -not re-planted- since they will give poor yield.

A lot of plants work like that. Apples very rarely come out tasting great if the tree is planted from a seed. You need to clone a good known apple tree from cuttings instead.
