Този хибрид между азиатска и европейска круша идва от САЩ , от разсадника на Cliff England, плодовете са много едри със свеж и сочен вкус на чбълка, Периода на цъфтеж е много дълъг и по този начин опасността от слана е сведен на минимум. Устойчив на огнен пригор и великолепен за прясна консумация. Разсадника ни го произвежда за първа година с калеми от собствен маточник. Може да се нуждае от прореждане, поради обилния си плододобив. Зрее 10 дни след Бартлет.
Плодовете се консумират след кратко лагеруване след бране.

History: Issued Plant Variety Patent# 4616 in 19xx by the United States Patent Office.
Rootstocks used: ***[will check my records- I recall it was on standard stock]; Said to be directly compatible with Provence quince [mis-named in the patent as "Providence"] and Cotonester acutifolia
Orchards grown in: Coal Mountain, GA.
Fruit quality: Flavor is ***. Texture is supposedly crisp when the fruits are smaller, then soft when fully ripe. Mr. Tonge, cited below, sings this fruit's praises, but many who have grown it do not share his opinion. A trusted fellow grower from South Georgia told me that he thought the name "Turnbull" came from the way its poor taste would make a bull turn and run from the fruit!

Fruit appearance: Roundish, apple-shaped.
Culinary characteristics: Originators claim it is great for salads, canned pears or any other purpose an apple might serve.

Harvest season: 10 days later than 'Bartlett' according to the patent.
Bloom season: ***; a few days *** vs Spalding. Said to be self-fertile.

Precocity: Said to be precocious. I moved away before my tree fruited.
Productivity: Said to be very productive.
Growth habit: Very vigorous;
