I have looked at the title of your
thread several times. I was intrigued and sorry you have not gotten an
answer to your question.
I always go to Wikipedia for answers. Here is what they said:
Cripps Pink is a cultivar of apple. It is one of several cultivars from which apples that meet quality standards can be sold under the trademark name Pink Lady.[1] Cripps Pink was originally bred by John Cripps at the (then named) Western Australia Department of Agriculture by crossing the Australian apple Lady Williams with a Golden Delicious; the result is a combination of the firm, long-storing property of Lady Williams with the sweetness and lack of storage scald of Golden Delicious.
