Lucky and Zaz, that list is one I wrote about 10 years ago. The original Thomas and Neel #1 are my hands down favorite trees for best production and best eating quality. Sparks 129 has gotten more productive as the trees have grown. I now rate it as better than average production though I can’t say what it will be like in another 10 years when the trees crowd.
For the deep south, Thomas and Neel #1 are hands down the best though they need a pollinator like Sparrow
For Iowa and Illinois, Sparrow, Sparks 127, Sparks 129, McGinnis, Emma K, and Sauber #1 are good starters
I have all of these varieties plus a few more and can provide scionwood. Send me a message in January.
Nut producing walnuts trees
I spent hours on the phone calling people who grow black walnuts to find out which ones were recommended most consistently. This list is my write-up on the possibilities.
-
Sparrow - a good quality, medium sized, rounded nut cracking out 28% to 32% kernel. It is a Protandrous early pollen source, which should be planted because most of the other top recommendations are protogynous. Nut quality is only medium but it produces strong seedlings. It is reported to be a consistently productive tree. The only reported flaw is that the kernel color is a bit mottled.
-
Kwik Krop - an excellent quality flattened oval shaped nut that cracks out 25% to 28 % kernel. Nut is oval, oblate, dented with a unique shape. It is a well-known tree that has been propagated by Stark nursery for years. The only complaints are that the kernel percentage is a bit low and that the production consistency is not as good as could be asked for. Kernel color is white to tan, occasionally amber, excellent flavor, and cracks relatively easy.
-
McGinnis - This is a small to medium sized nut with excellent kernel color and about 35% yield. It has two flaws in that kernel extraction can be relatively difficult and the flavor is not quite as good as for example Thomas. The ortet originated in Nebraska so hardiness should be excellent. It is reported to have very high anthracnose tolerance. Original tree was cut down age about 108 years and in poor health. Mr. Mcginnis had picked up the nuts from this tree since he was a young boy @70 years ago.
-
Surprise - an excellent quality, precocious, productive, rounded nut cracking out about 35% kernel. Gerald Gardner found it growing as a seedling of some nuts brought from selected cultivars growing in Pennsylvania. This tree tends to grow fast with somewhat prostrate form making it a poor timber producer except when staked and carefully trained. It is a rapid grower under good conditions and can reach early production within 5 years. The ortet is thought to have been destroyed when the nursery row it was in was bulldozed out a few years ago. Its only significant flaw is a tendency to produce up to 10% blanks.
-
Sauber #1 - Is a large nut of excellent quality and kernel crackout above 30%. Get graftwood from Bill Lane in Missouri. He got his trees from Mr. Sauber. Several people have propagated another tree possibly Daniels under the Sauber #1 name. While kernel quality is excellent, size is medium large. There are several other trees with the Sauber name. Sauber, Sauber#2, Sauber#3, etc. The best of the bunch is the Sauber#1 as obtained from Bill Lane.
-
Emma K - a good quality nut cracking out about 35% with a distinctive oval shape. Has flaws in that nuts tend to hang on the tree after ripe and the kernel darkens quickly if not promptly harvested and hulled. The hulls are unusually hard to remove. Emma K is possibly a seedling of Ohio. Tree has spreading form so not adapted for timber production though it does grow rapidly and could be pruned and trained to meet timber objectives.
-
S129 - An Archie Sparks selection, seedling of Hay #1(Thomas Myers), very vigorous tree, kernel crackout of 30% or more. Brian Sparks says the nuts are large and excellent quality though the tree may not be as productive as could be desired. This might make an excellent dual-purpose timber and nut-producing tree. Must be staked when young because it grows so fast it is often leaned over by wind. It can easily grow 7 feet in a year.
-
Beck - A small nut with consistent production and good anthracnose tolerance. It is reported to do well in Indiana and other mid-western to eastern states. Bill Heiman reports it as one of the most consistently productive trees.
-
Hay #1 - a good quality large nut with good anthracnose tolerance and good production. Has a tendency not to fill all the nuts and the kernel quality may be poor. Needs good soil and moisture conditions and full sunlight. Also propagated as Thomas Myers. Production consistency is poor in my opinion.
-
Rowher - has excellent anthracnose tolerance and good nut quality but poor production. Often propagated but few people have producing trees. I have not seen any nuts so don’t know much about nut quality.
-
Davidson - A large nut with reported excellent anthracnose tolerance but slight to very poor kernel quality. Kernel darkens rapidly if not handled properly. Gerald Gardner considers it one of the poorer quality nuts he has. May have the highest anthracnose tolerance of available cultivars.
-
Ogden - A medium large nut of about 25% kernel. Is reputed to be one of the most productive trees available. Has fairly good anthracnose tolerance. It has potential breeding value because of its high production. It is not reported as being productive at all locations.
-
Bowser - an excellent quality but small nut cracking 37% with easy kernel extraction. The only flaw with this tree is poor production. Not economic in a large planting. May be useful for someone wanting a backyard tree to produce high quality nuts.
-
Thomas - a medium large nut with easy crackout of about 25% and and excellent flavor. Tends to alternate bear and is susceptible to anthracnose under high moisture conditions. This tree has very good breeding prospects. It was first propagated in the 1880’s from the ortet in Pennsylvania. Numerous misnomers propagated as Thomas since then. Has produced some excellent seedlings such as Hay #1. The tree is lateral branching and producing. I picked up 25 5gallon buckets of walnuts under a Thomas tree that was about 38 years old and 12 inches diameter. Be sure you have the original Thomas!
-
Football II - a fair quality medium large nut that cracks well. It is susceptible to anthracnose and also to nut stress defoliation. This usually results in poor quality kernels. Excellent production and with irrigation, may be economic to grow. Highly recommended by Gerald Gardner though he acknowledges its anthracnose/defoliation problem. The ortet is thought to still be alive though access may be a bit difficult. May be valuable for breeding if crossed with an anthracnose resistant tree possibly Davidson?
-
Rupert - Per Bill Reid, a small nut, productive tree, fair leaf disease tolerance.
-
Farrington - A large nut with fair production and good leaf disease tolerance. Deserves to be propagated more than it has. I have not seen any nut samples.
-
Mintle - (thought to be identical with brown nuggett) is a small nut that cracks out well but the kernels darken readily. It is reported as a poor selection in high rainfall areas such as the southeast. Does well in Iowa and other parts of the mid-west. Needs to be compared with Brown Nuggett to resolve the ongoing identity question.
-
Eldora - Highly recommended in Iowa, consistent production, good leaf disease tolerance, similar to sparrow but slightly better quality.
-
S127 - A small to medium sized nut that produces well in Iowa but tends to have lower kernel quality this far south. It has a high kernel percentage and fairly good cracking. Nut shape has some similarities to sparrow though totally unrelated. Kernel shape is more similar to Neel#1.
-
Ozark King - Is a large nut with a thick shell cracking about 27% kernel with excellent kernel quality but poor production. Cracks well with a “mouse eared” shape to the kernel lobes. Tied with Bowser for highest quality kernel in my opinion. Best considered a backyard tree.
-
Neel#1 - Selected by Robert Neel, Barboursville, WV. A very good oval nut with a unique shape. Good anthracnose tolerance, good production, excellent growth with a distinctive central leader and spreading branches. The flavor of this nut is comparable to and maybe slightly better than Thomas. Appears to be one of the best adapted trees in the Southeast. W. Donoho has several producing trees and Fred Blankenship has some in production by now. I consider this to be one of the trees I will definitely propagate for long term timber and nut production.
-
Pounds#2 - Leon Pounds selection border of Kentucky and Indiana. Thought to be a second generation Thomas seedling. Good production of good quality nuts with slightly higher kernel percentage than Thomas. Not enough known to reach definite conclusions. The nut samples I looked at were very good though not above 31% kernel.
-
Wiard - Richard Goldner in Michigan highly recommends this tree. It is an older cultivar with a small nut. It is susceptible to anthracnose that is probably exacerbated by its high production. May have breeding value especially for trees to grow further north. This tree may be difficult to find. Perhaps should get graftwood from Mr. Goldner if possible.
-
S147 - also an Archie Sparks selection as a seedling of Hay#1. It has high kernel percentage, good kernel quality, and a large nut. Tree grows fairly fast with acceptable timber form. I am evaluating this one for possible commercial production of nuts.
-
Vandersloot - an older cultivar with very large but thick shelled nuts 25% to 28% kernel. The tree is reported as a rapid grower with good production though it is susceptible to anthracnose and stress defoliation.
-
Todd - Original tree found by McDaniels in Ohio. Produces a very large nut with good kernel percent. Has not been propagated to any significant extent.
-
Cannonball - Reported to produce nuts 4 times larger than Thomas with over 30% kernel. Ortet found near Wilson, NC. Potential unknown because nobody has trees growing.
-
Ohio - reported as a thin shelled good quality nut with good anthracnose tolerance. An older cultivar that has been pretty much supplanted by later selections. There may be 3 different trees making the rounds as Ohio.
-
Stabler - Produces some to all nuts with a single lobe. Reported very good flavor and quality if under excellent care but is susceptible to anthracnose.
-
Clermont - Produces an excellent quality thin shelled nut. Original tree long since cut down. Per Archie Sparks, there are 4 different trees being propagated as Clermont. One may be a misnamed Myers.
-
Myers - aka Elmer Myers is a good quality thin shelled but small nut. The tree is reputed to have excellent anthracnose tolerance but is not productive especially north of Missouri.
-
Burns - A very small thin shelled nut with exceptional crackout. Reported productive into Ontario.
-
Cranz - A fairly recent selection with reported excellent production in Iowa.
-
Deming Purple - Selected for its purple foliage in spring.
-
El Tom - A cross of Elmer Myers and Thomas.
-
Grundy - An Iowa selection. NNGA annual reports have numerous articles.
-
Harney - An older selection still in propagation.
-
Tom Boy - Found growing (about 5 trees out of about 200 planted) as a supposed grafted Thomas tree by Bill Lane. The tree leafs out earlier than Thomas and is more regularly productive.
-
Shessler - Found by Sylvester Shessler as a seedling of Tritten. A moderately good quality nut.
-
Stanek - medium quality nuts, relatively low kernel percentage.
