ReplytoOlpea-topic Harrow Program Pears

The HS grafted on an apple will not last. I would invest in it by putting HS on a good rootstock or a good pear tree. I think you will like the taste of HS.

Thanks. From what I’ve read, HS will be a good bet here… only concern being the late harvest (we have had snow in September on some years, though usually not before Halloween). I had some scionwood and thought if the graft took on the apple, I’d at least have some some scionwood for future years… so not high expectations, but a good experiment. I did add one graft on my existing pear, but it didn’t take (kind of at the limits of scionwood… this was 3 weeks ago and it had started to sprout); however the Harrow Delight on pear did take.

I am adding a pear next year, and so likely it will be an HS on OHxF 87, which I believe does well locally.

Thanks J-A - great to know about other fireblight resistant varieties that are great tasting!

I looked around and couldn’t find the Uta locally here, but will put it on the list to look for! Are any on your list particularly cold hardy (Z5 here in the states) or late bloomers?

kokopelli5A, the varieties that I have mentioned are all of very high quality and productive.
All those mentioned in my previous post are late maturing.

Early ripening pears, I have these in my collection (I’m sure I’m forgetting some):

  • Beurré Giffard
  • Dr Jules Guyot
  • Q-Tee Celina (very little sensitive to fire blight)
  • Williams
  • Beurré Morettini
  • Précoce de Trévoux
  • Clapp’s Favorite
  • Carmen
  • Etrusca
  • Harrow Deligh (fireblight resistant)
  • Harrow Delicious (fireblight resistant to bacterial fire)
  • Harrow Bounty (fireblight resistant)
  • Président Héron (very little sensitive to fireblight)
  • Selena Elliot (fireblight resistant)
  • Dessertnaja (very little sensitive to fireblight)

Rossn, Uta is a really delicious variety (it reminds me a bit of the Supercomice Delbias variety from the French breeder Georges Delbard), it is a really good pear variety, and you have no problems with it, it is late blooming , when the late frosts have passed .

Thanks for the update. I’ll keep them in mind. A lot of them aren’t common around here.

By “Precocious” I mean set fruit after a couple or three years in the ground, rather than ripen early.

The rapid entry into production in pear trees depends more on the type of rootstock than on the variety itself.
The different types of rootstock from quince that the varieties of pears grafted on them, enter production very quickly, but have the disadvantage that they do not tolerate calcareous soils, and are very susceptible to soil diseases.
Due to the high pH of my land I graft the pears on the rootstock pyrus comunis and this rootstock makes the pear trees enter more slowly (more years) in production.
In your case that you are in risk areas due to firebligth, it is necessary that you use rootstock resistant to the bacteria.
In the OHxF series there are very good rootstocks (Farold 87 Daytor is fantastic).

Both variety and rootstock influence fruit production. Harrow sweet does produce very quickly. Grafted on callery harrow sweet takes 1-2 years to produce wheras harrow delight takes 2-3 years. Clapps favorite 10 -12 years + in this area. Certainly quince cannot be used for the above mentioned reasons in kansas. Quince gets quince rust, fireblight, is not drought or high ph tolerant and more. Quince or ohx333 can decrease the number of years it takes to get fruit as mentioned above. 333 will work in Kansas in wet areas but not in my dry areas since the root system is not deep enough. Callery or BET or ohxf97 or 87 are the best choices here. I prefer callery or bet. I do not care for harbin but do have some like quince for experimental purposes. All quince grafts and rootstocks have been removed after i did a few years testing with them. Most died by natural causes quickly within 3 years. Bartlett seedlings are fine here if they are treated or grafted over before fireblight becomes an issue.

Sorry Clarkinks, but I am very short on time (I have a lot of work).
Forummate Beetree had doubts about his plant of persimmon germinated of a seed , has two sprouts (Beetree thought it was a chimera) and I have explained the difference between chimera and polyembryonic seed.

Today I wanted to do a photo report of some varieties of pears that you are going to like.

Very important .

Indeed I agree with you.

I have also observed the phenomenon that using the same rootstock there are varieties of pears that enter production much earlier than other varieties.
And curiously, the recently obtained varieties ( modern varieties ) come into production much earlier (I mean years) than the older varieties (varieties from the 18th and 19th centuries).

Here I do not understand the reason, since genetics is very capricious

I have to take the pictures, because I know you are going to love them (you are a lover of pear and apple trees like me)

@Jose-Albacete

Thank you for documenting your collection. It’s getting to a point where I know much about a pear by looking at it. Once in awhile I see a unique seedling like the one @39thparallel brought me. Very unusual pear indeed with virtually nothing known about it.
