sconticut, Kellogg's Breakfast 'X' Cross is the result of a natural cross. The plant(s) should have shown potato leaf type foliage. Yes, open-pollinated - save them seeds. Three week germination period is unusual - I grew many KBX and germination was 7-10 days.

KBX was my most productive,weightwise. Several were over 2 lbs and most over 1 pound. All the Mrs Asian friends loved them. I didn't find them that appealing. I,with the KBX,now know what fruity means as this has a fruit like Taste to me. Grew this one in isolation in case I wanted to save the seeds.Will probably offer the seeds or toss them.

Thank your for the KBX answer, folks, Have a couple of beauties ready to pick for fermentation tomorrow, after all this rain ends.
