large yellow squash
I grew a variety of yellow squash that I can't find the name or seeds anywhere. It's round to oblong ( sometimes looks like spaghetti squash but isn't ) it grows on massive vines 15 to 40 feet long and is very prolific & disease resistant . I thought I planted regular yellow squash & don't know where it came from .Best I ever had. Help ! I am saving seeds but it could be a hy-bred or it might fail. All the best - Rick
Without a photo I am going to make a total guess:
One Ball which is a hybrid round yellow zucchini hybrid with long vines. Other prolific yellow squash include Horn of Plenty (yellow summer squash), and Early Prolific Straight Necked.
Feel free to send me a photo.
