Average yield (pounds nuts per tree) of 'Amling' each year from topworking in 2008. The base tree was planted in 2002, same as 'Desirable' and 'Stuart'.
Texas seedling selected for good resistance to pests.
We topworked several trees to this selection in 2008. So far, this selection has beautiful dark green foliage and excellent resistance to most pests. The medium sized nuts have a high quality kernel and are easy to shell. The knock on this culitvar has been that it doesn't have adequate yield potential. It is too early to tell in our trees, we should know the answer soon. In 2012 clusters were fairly large, and the tree seemed productive. I expect the trees to be back to a similar size as the control trees in a year or two, and we will be able to compare yields. Right now, I don't think yields will be too low. However, nut size in 2013 was quite small (62 nuts/lb) and this is too small to get a good price in a market that favors large nut size.
This is my favorite cultivar for a yard tree as the nuts are high quality and I have not seen any pest problems with this cultivar. I would also recommend it for organic or low-input applications, and often recommend it as a pollinator for 'Elliott' or 'McMillan'. If yield turns out to be adequate, the only limitation to this cultivar is that it has only medium-small sized nuts.
