Seedling from Waycross, Ga.

Comments

'Tobacco Barn' was given to me by an Alabama extension agent in 2006. He noted that the original tree did alternate but no scab had yet been seen on this tree. I have not seen any scab on our trees in a sprayed orchard yet.

So far 'Tobacco Barn' has produced a nice quality medium sized nut. Kernels are well filled and pretty, similar to 'Sioux' but not as bright. It shells very easily into complete halves. Harvest date has been a little later than 'Desirable'. This tree was topworked into older trees, so yield data can't be compared to the check cultivars yet. As the trees begin to produce the same as the check cultivar we will get a yield comparison. Bud break is very early in 'Tobacco Barn', and it should not be planted in north Georgia.

Right now, I am not very high on this cultivar. While it has scab resistance, it is small and is showing signs of being very black aphid susceptible. If I was looking for something new to try I would plant 'Zinner' over 'Tobacco Barn'. I suspect we will discontinue testing of this cultivar soon.
