Grape hybridization does not necessarily add hardiness

Many growers have jumped to the conclusion that when a muscadine is crossed with a table grape it instills a gene in the new plant making it more cold hardy which is typically not true. It does increase fruit production and eliminate diseases of any kind in some cases
As many of you are aware muscadines are from the South and you can read more about them here Vitis rotundifolia - Wikipedia"The scuppernong is a large variety of muscadine, a species of grape native to the Southern United States. It is usually a greenish or bronze color and is similar in appearance and texture to a white grape, but rounder and larger and first known as the ‘big white grape’."
Be careful with the optimistic zone 6 status even with the best nurseries regarding muscadine or any other grape
Zone 6 Grapevines - Vines Best Suited To Hardiness Zone 6 Planting
Companies dont really point out there is a zone 6a and 6b with muscadines✓&term=Muscadine&commit=Search
So far noone i know in my area is growing muscadine or any hybrids. By the way even if your zone 6b or 7 remember you need a long growing season similar to theirs in the SW United States to ripen muscadine. I suspect there are varities that will live in the colder parts of Kansas but one of us needs to take the time and expense and do the research.
All that said muscadines such as nesbit should survive in Kansas and likely ripen most years and if i decide to pursue this my research starts on this grape Nesbitt Muscadine Grape - Grape Vines - Stark Bro’s
