I am doing some investigation on the Miracle Wheat episode, and I have a question that I don't know the answer to, and I can't find the answer online.
It seems that, from what I have learnt online, that wheat is a self-pollinating, "perfect flower". This means that once there is a strain that has a quality that's desirable, all you have to do is plant it, and that feature will remain "forever". Essentially the new plants are all clones.
Given that information, this statement by Penton does not make sense:
He was evidently quite sincere in selling the famous grain but was more positive about its qualities than he should have been. Miracle Wheat was apparently no more than a mutant strain, a “sport.” It soon lost its outstanding vitality and was not, as he believed, a sign that the earth was soon to be restored to paradisiacal conditions.
Why did the "miracle wheat" lose its outstanding vitality? Wouldn't it remain if what I understand about wheat is true?
P.S. I have already asked some agronomists, waiting for their response. But if someone here knows about it, why not?
