Compatible Avocado flower types? (forum)

John Mc starts with ...
I was thinking of grafting a compatible flower type scion to my Hass avocado tree hopefully to increase the yeild. The big question is, what cv would be the most compatible to help increase yeild? Yesterday I grafted a couple of sheppard and sharwill scions but not sure if they are the best choice? I have also wondered why Daley's don't double graft Avocado trees for that same reason.

John, Ettinger is the best pollinator for Hass but you probably wont get any fruit from the Ettinger itself. At least I don't down here, I still have two Ettinger trees going just for pollination purposes. A double grafted Avocado would probably be pretty hard to keep balanced since the vigour and shape of the tree is so different between most varieties.

I have 4 Hass trees although only 1 is any good lol. One is stunted, one is still a fresh graft on a seedling and one is growing in the shade under a big wattle. Lucky for me the one good one has 300+ fruit on it

Hi John Mc,
Edranol, Sharwill and Zutano (all type 'B'), help pollinate Hass.

Jason, how old is the Hass tree with the 300+ fruit on? (about 10 years?)

Brendan, yep it's around 9 years old. That tree has been a winner ever since the day I planted it. Just got lucky with a good tree with good roots in good hole.

The reason Ettinger is used for a pollinator for Hass is that it goes through 2 males cycles for each female one?? I think (something different about it). Plus it flowers later than most or all the common type B trees, so it's more lined up with the late flowering of Hass

Jason, my 2 year old Hass is in full flower now, probably because of where I live? Hopefully, it 'should' bear next year :-)

You might get some fruit set this year, depending on how big the tree is. I imagine you can get plenty of feet per year growth out of an Avocado tree up there.

Some of my Avocados are flowering now but Hass wont be fully in flower until Late September and early October I guess (that's about normal for me).

Unfortunately the ones that are flowering now are type B's and it's miles too cold for fruit set on those during the night at this time of year, lucky the last few flowers will (probably) catch some warm nights

My B's are 2 shepard and 1 sharwil and my A's are reed,hazzard and wurtz and all 6 are flowering now and together for a change.The sequence of flowering varies year to year.All B's pollinate all A's and it is better to have good ones not just pollinators.NSW is a little cool for shepard and I consider it my best and most productive type.Hass,bacon,rincon and wurtz reputedly have the greatest tolerance of cold.

I want to graft a B variety onto hass. Will fuerte help pollinate hass or does it flower too early? Surely flowering between the two might overlap once a large tree. Or would I be better to put sharwill with hass? I want two varieties with good fruit, not just a "pollinator"

Hi gimme, you could try an Edranol. Very good fruit and does pollinate Hass. My pick for sure!
Fuerte will pollinate AND 'cross' with Hass.
Zutano will also pollinate Hass.
Nabal, Shepard, Linda & Walden might work too. Good luck.

Thanks Brendan. My recent success grafting has got me excited with the possibilities.

Don't forget gimme, if you 'cross' the Fuerte with the Hass, the seeds from those fruit 'might' produce new varieties which you can call Fass or Huerte! LOL :-)

Lol, I love the sound of hurte. I have found a graph in an old book that says fuerte and hass hArvest only just overlaps so I don't think they will flower together. So I might start doing hass+edranol and hass+sharwill combo's.

Avocados are 99% self-fertile if I'm not mistaken. Only in tropical weather do male flowers and female flowers not overlap.

I think fruit yield would increase more than 1% when growing a and b type together. There wouldn't be so much fuss about cross pollination otherwise.

Well you are the one creating the fuss :P

I'm happy for someone to prove me wrong, but this is what an avocado expert once told me. The fuss is necessary for very warm climates which polarizes the time a plant's male and female flowers are open, thus preventing self pollination. In this instance having a type A and type B solves the problem because the male/female opening periods are opposite between types.

Perhaps the 99% per cent was an exaggeration, but there are other explanations for why your yield may not be great. Avocado flowers are very bland to a bee's eye and tend to be ignored. Have you tried hand pollination?

I'm not growing any big trees. I didn't start this thread so other people seem interested in cross pollination aswell. I'm propagating them so just trying to find out which two varieties might be most advantageous together.

Theres a well documented 40% difference in crop between different pollinaters let alone no pollinator at all. Fruit size and shape depends partly on seed size and shape which depends partly on the pollinator just like every other living thing. The Avocado expert/grower who was Mr 99% would have been bankrupt years ago. The pollinators work much better within 10 metres too. Past 20 metres the cross pollination is much less effective
