Passe Crassane pear

--- Quote from: SoCal2warm on April 17, 2019, 03:56:58 PM ---It is believed Passe Crassane is a pear-quince hybrid, but not known for sure. However, there are a number of things that point to that direction. Very dwarfed growing habit, parthenocarpic fruits, very good compatibility on quince (which the great majority of pear cultivars do not have, with the notable exception of Comice). Not to mention the very firm and hard fruits, notorious susceptibility to fireblight of this variety, several other things as well.

"...the passé-crassane, is actually a pear-quince hybrid that was developed in Normandy. It is particularly useful in cooking because of its firm, grainy flesh, but it is also tasty eaten raw." (The 150 Healthiest Foods on Earth: The Surprising, Unbiased Truth about What You Should Eat and Why, by Jonny Bowden, p144 )

The French article claims it was a cross between pear and quince.

This could just be a rumor, however. I am not able to find any original sources.

En 1855, à Rouen, le pépiniériste Louis Boisbunel a l'idée de croiser une poire avec un coing. Leur enfant est la passe-crassane. Elle a hérité d'un peu de la physionomie de son « père » : elle est très joufflue, presque ronde, parfois bosselée. Sa peau est jaune marbrée d'ocre. Vous trouverez cette poire, plutôt bon marché, de décembre à avril.

In 1855, in Rouen, the nurseryman Louis Boisbunel has the idea to cross a pear with a quince. Their child is the crassane passer. She inherited a little of the physiognomy of her "father": she is very chubby, almost round, sometimes bumpy. Its skin is yellow marbled with ocher. You will find this pear, rather cheap, from December to April.

also entry in L'Encyclopédie visuelle des aliments, 1996, Quebec, page 213 :
La poire passe crassane est originaire de France créée en 1855 lorsque l'arboriculteur normand Louis Boisbunel croisa une poire avec un coing. C'est la poire d'hiver par excellence, car elle se conserve facilement.
created in 1855 when the Norman arborist Louis Boisbunel crossed a pear with a quince. It's the ultimate winter pear because it can be preserved

In France all specialists and also INRA declares the passe crassane as a PEAR.
It is not in any case a hybrid pear and Quince.
All the books of the time speaks of PEAR no hybrid.
so I think in the French books this would have been said by Mr Boisbunel.
And the INRA confirmed to me that it is simply a PEAR.
