‘Vavilov’ (it's pear fruit is the 'European pear type, with the crunch of an Asian pear')(This cultivar is also known as, 'Hybrid VII', 'Rousselet of Stuttgart x Dr. Jules Guyot No. VII' and as 'PI 337446'). This once unnamed pear variety was eventually named after the 'Russian-Soviet agronomist and botanist', 'Nikolai Vavilov'.

The quality of it's fruit is '7 out of 9', this was one of Joseph D. Postman's 18 very favorite pear varieties. For more than 35 years, as the Genebank Curator, and as the 'plant pathologist' for the USDA's Corvallis, Oregon portion of the 'Agricultural Research Service', it was in part Joseph's job to find, to eat fruit from, to select, to organize, to care for, and to present one of the largest collection of pear trees in the world, pear trees that originated from around the world, he helped to create the living ‘World Pear Collection’, representing the genetic diversity of pear cultivars and species. So despite him having personal preferences just like everyone else, his opinion still is very valuable, since he's such an expert who has tried fruit from so many different varieties.

It's production is medium production. 2 to 3 years to first fruit (precocious). It's fruit is very sweet, and 'aromatic', it's just like a juicy European pear with the crunch/crisp of an Asian Pear, the fruit of this cultivar is often grit free. The texture of it's flesh is a '3 out of 9'. The color of it's flesh is 'cream'. The peel's overcolor is 50%. It's overcolor is a reddish/pinkish blush, with speckled color, that outside appearance looks similar to that of the Forelle variety of pear. It overcolor type = splashes.

Amount of russeting is 3 out of 9, it's fruit does not oxidize after cut, the peel's background color is 'yellow green', fruit skin lenticels quantity '3 out of 9', fruit skin lenticel size '5 out of 9',

The bloom Density of this cultivar is a '6 out of 9', this cultivar has a strong resistance to 'leaf scab disease', this cultivar has a strong resistance to 'pseudomonas', a strong resistance to 'rust disease', damage caused by fruit scab '2 out of 9', damage caused by 'blister mites' '3 out of 9'.

It's a hybrid cross between Rousselet Shtutgartskii x Dr. J. Gujo = Rous. of Stuttgart x Dr. Jules Guyot. It originated from Leningradskaja oblast (Saint Petersburg), in the Russian Federation. It was released in 1968 by the 'N.I. Vavilov Research Institute of Plant Industry'.

Out of 5 different pear varieties, that were created out of the same hybridization project ‘Vavilov’, and 'Rousselet of Stuttgart x Dr. Jules Guyot Hybrid V' appear to be 'the very two best'. They are actually nearly identical in several ways, including to fruit. Although one major disadvantage of growing ‘Vavilov’, it's not as fireblight resistant as 'Rousselet of Stuttgart x Dr. Jules Guyot Hybrid V' is.
