Warren Pear Trees are said to be self-fertile. We can as the name implies get fruit with only one plant. It would be very few fruit! The tree is very difficult to pollinate well for whatever reason so I grow mine with Karl’s favorite aka ewart grafted into the same tree which works.
If you went to Warren Pear – Trees of Antiquity you will find this description
The Warren pear tree was named for Thomas O. Warren, a founding father of the North American Fruit Explorers (NAFEX), who discovered this gem in Mississippi, in 1976. The Warren pear is medium to large, long-necked, drop-shaped fruit is faded green with an occasional red blush in full sun. That said, the Warren pears can vary in size and shape. The pears are rated equal to Magness by many. The Warren pears are sweet, spicy and very juicy, buttery, silky flesh with no grit. Pyramidal tree shape. Fire blight resistant. One of the best for providing a source of pollen to other European pear trees. Please refer below for more information on the Warren pear trees for sale.
OK finally to answer your question almost all pear trees are suitable for pollinating each other as long as they bloom at the same time. Harrow delight might be a better pear for pollination grafted on another for multiple reasons. It’s my opinion avoiding pears with similar genetics is best. Siblings or parents are not good pollinators. They will work in some cases but trees of diverse genetics work better. Magness and Warren are siblings and comice a parent. Someone is going to say it so before they do there is a term called pathenocarpic which applies to comice.
In climates such as California comice may produce fruit with no pears around sometimes. This link mentions it Pollination – Pear | WSU Tree Fruit | Washington State University
I discuss that term here Parthenocarpic Pears
Finally there is a wild card in here that needs discussed which is the callery pear. We know it naturalizes all over the country now and was added to some states invasive lists. It’s highly unlikely you live in an area free from ornamental wild or tame pears and they will pollinate your pear trees. Why if Warren is related to comice would it not be parthenocarpic as well like its parent? The fascinating truth is that it is said to be parthenocarpic on some websites but is also reportedly self pollinating at half the references available. My Warren definately has pollination issues. My crops are very heavy in comparison to what others get but my tree is half ewart aka Karl’s favorite. Ewart pear I grew specifically to pollinate Warren Karl's Favorite aka Ewart Pear . Finally understanding pollination is key which is described here Pollination Requirements - Cooperative Extension: Tree Fruits - University of Maine Cooperative Extension
