'Jutras Apple' Winter Squash

11 years ago

We have selected many Cucurbita maxima ''Turk' Turban'' fruits and got a mini variety, which could not develop orange or red. This TT green mini we selected to grow not larger then 4" in diameter with a hight of only 3". And in 2014 this green supermini was pollinated with the selfed Atlantic Giant 1385.5 Jutras 07, the fruit which had the best offspring ever seen. The maker of most giant pumpkins, which Joe Jutras grew in Rhode Island, made one of my smallest ever (and healthy) TT mini in the parental generation 14" large in diameter and 10" high (8" stalk to blossom axis) with xenia (influence of the pollen on the growing mother's fruit behind the flower) on a 5-lober fruit.
A few years ago orange and orange-green mottled TTs of normal size were pollinated by AGs and showed only 30 to 40 % more in diameter through xenia and same hight as the mother variety in parental generation, but F1 grew 15" in diameter and around 10" hight.
That was nearly three times the measures of the mother.
For the Rhode Island Greening winter squash Cucurbita maxima 'Jutras Apple' now nearly three times would say: around 35" in diameter and 24" SB-axis when self pollinated in the F1 next year.

Only the smallest two were chosen to be mother of the Jutras Apple.

...only 30 to 40 % more diameter in parental generation two years ago: the two fruits right outside.

F1 of that TT x 922 was 'Delilah' in 2013.

Cucurbita maxima 'Delilah' x Cucurbita ficifolia
C. maxima x ficifolia 'Simson' for North America but
C. maxima x ficifolia 'Mitschurin' for Russia, because the botanist Mitschurin (or Michurin in English) made so many vegetable and fruit varieties for the harsh Russian climate with grafting and seed from grafted plants, which he had promoted with hybrid vigor. Most of these so-called hybrids can not seriously be seen as true hybrids.
Mitschurin was the favourite botanist of Lenin and Stalin, and Lyssenko made a botanical doctrine for the Sowjet world on the base of MitschurinÃÂ´s botanical humbug.
But until now there is a city of Mitschurinsk in Russia with a great complex of green faculties.
The variety C. maxima x ficifolia 'Mitschurin' or 'Simson' can be grown in regions of Russia and Canada, where no other pumpkin or winter squash matures with a best storability.
