Tropical Fruit Discussion / Annona disease ID?
« Last post by New_Jungle on December 14, 2018, 11:45:21 PM »
Hi I was wondering if anyone here can help me ID this condition. It seems to only be affecting my annona seedlings. So far has hit my purple sugar apples, cherimoya, atemoya and Rollinia seedlings. Starts off as yellow lines on the leaves which turn black. Eventually the leaf crumpled up, dissecates, and falls off. Thank you guys again!

June 23 grafts pushed nicely:



Are you using RBII panels as open bottom container or covering the bottom somehow? I planted a Holiday and Alphonso with open bottoms recently and wondering if I did the right thing.

You did the right thing.  No bottom, best of both worlds - big pot using excellent potting soil, roots harvest water and nutrients that collect in native soil.  Permanent location.

Good to hear, my Holiday wasn't doing well in the ground so I transplanted it. Old leaves are dying but the tree started to push new growth.

Hereís a brief summary of our new technique for growing Polyembryonic mango seedlings.

Plant a Polyembryonic mango seed. You will need at least two sprouts from the seed to almost guarantee you get a clone. Based on literature, there can be more than one zygotic seedling so I canít say for sure youíll get a clone.

If you get a lot of seedlings coming up from a seed, select the largest one to use as rootstock and select the next biggest one as a scion donor to graft onto the rootstock. Before you graft onto the rootstock, ensure you save at least one branch from the rootstock in case it is the clone. Because the scion donor is slightly less vigorous, it should be grafted up higher.

In a batch of seedlings coming up from one Polyembryonic mango seed, if there are multiple seedlings that look the same and have similar growth rates, there is a good chance that they are the clones. Remember that I have hypothesized that the Zygotic seedling arising from a Polyembryonic seed can have the potential to yield good tasting fruit. I believe this to be true because such a seedling will have at least 50% of its genes from the maternal parent and the other 50% of its genes will be from another variety or itself.

Even if the zygotic seedling is selfed( pollinated by its own pollen) there will be rearrangement of its genetic material and the resulting fruit can be very different from the parent fruit.

Since most of us are only growing top tier varieties, the paternal pollen(if not selfed) will likely come from another top tier variety.

Valuable work you guys are doing, thank you for taking time to share.

Only one of the three NDM seedlings had two seedlings growing, I cut the weaker and slower one of the two few months back, all three are single seedlings growing in individual pots now. I may in future want to use one as rootstock for another variety and keep the two to grow in the hope I get good NDM fruits from them one day .

In the event I wanted to participate in some of the experiments you guys are doing, what Polyembryonic seeds besides NDM would you recommend? NDM seeds are difficult to get locally.

Thanks

I split a few poly seedlings and planted in multiple holes also.  That is also possible and the plant will take that no problem if its just a few months old or less.  Just carefully seperate them.

We had a terrific Kutejensis at the agro park in Tenom, really one of the best fruits of our trip there.  However, this was in August, so donít know if that tree would have fruit now.  Also the tree is in an area outside of the public gardens but you can get someone to take you there.

ManVFruit,

NDM is a great variety to grow from seed.

Brad and I have actually come up with a better way to grow out Polyembryonic seedlings compared to what I recommended about a year ago. Last year, I recommended that we plant Polyembryonic seeds and simply let all the seedlings grow but in our field plantings, we noticed that the seedlings started pushing each other aside, causing them to grow slanted to one side.

Brad came up with the idea to graft one of the seedlings onto another seedling so that we can have a single trunk with two seedling varieties coming out of it. In hindsight, this should have clearly been foreseeable but we have so many different projects we are working on that itís hard to put too much thought into any one project.
