How important is “appy” color vs. performance or can you have both?
Your mare is quite a cutie! :yes:
First, let me ask you how important is appy or knab coloring to you?
Since she is heterozygous for the LP gene, IF you breed her to a stallion with the same genotype, i.e., LPlp, then the following will be the result:
25%LPLP, fewspot or snowcap
50%LPlp, any type of pattern could result depending on the presence of PATN genes, particularly PATN1… but, you may only get characteristics…
25%lplp, i.e., SOLID with no potential for any appy/knab coloring ever…
IF appy/knab coloring is paramount, then you should consider a fewspot or snowcap stallion, i.e., LPLP, and the resulting outcome would be:
50%LPLP, fewspot or snowcap
50%LPlp, any type of appy/knab pattern or characteristics…
IF color is not so important to you, then you can consider any type of stallion and I guess I think it would be prudent to look for stallions that are competing in/proving themselves in your discipline, combined driving, or some other discipline that could produce an offspring to compete well in your discipline… Maybe ???eventing??? :lol:
I tried to look up to see what horses, particularly stallions, are currently competing in combined driving and I got completely lost, so I will stick to what I know, dressage! 
Personally, I have several Waps offspring, they are lovely horses, and a few of them have been great producers in my breeding program… Regarding performance, I have a 10 yo mare doing second level dressage, BUT, it IS a struggle for her due to her weak loin connection and slightly downhill build… she is sired by Wap Spot and out of the same TB mare who is the dam of Waps Rolls Royce, among many! Personally, if she had not had an injury when she was younger, which impacts her soundness and jumping capacity, she would have made a much nicer hunter… she does have a very “pretty” form over fences… Since I have a couple of doses of Hollywood Hot Spot, aka Woody, frozen semen in my tank, I have considered breeding her to him… the resulting foal would still be 1/2 TB by blood, and I would still have a pretty high liklihood of seeing a foal with appy color/characteristics (75% overall), AND, Woody will definitely help short this mare’s back and improve her loin connection!
I also have an offspring sired by Hollywood Hot Spot, out of a foundation bred appaloosa mare… He is a great young gelding, though, as a long yearling, is in a rather awkward growth state right now… :lol: He will make a very nice, all around sporthorse for a devoted amateur…
I have a young 4 yo stallion, Waps Limited Edition (Waps Applause x Waps Blizzard/Wap’s Reflection) who I think/hope will be an eventer… He has quite a nice jump and a really nice canter… his trot is mediocre now, but it is the gait that can improve the most with training, so train we do! But, his sire, Waps Applause, had a proven and winning performance career in hunters to 3’6" and dressage and his damsire, Wap’s Reflection, also had a great career in dressage… So, time will tell!
And, I have a couple of offspring sired by RDF Ti Kha Atta Rain, out of one of my wonderful Wap mares… Now, THESE babies are really awesome! I would repeat that breeding again and again, but Atta has been exported to Scotland…
In addition to my appaloosa breeding program, I also have TBs, warmbloods, and Knabstruppers…
Regarding Knabstrupper stallions here in the US, there are only a few to choose from… Kathy has already mentioned Colorado Skrodstrup, aka Fable, and I do think his excellent performance career, in addition to his awesome performance in the 70 day stallion test, makes him a serious contender for you mare. At least one other Knabstrupper stallion in the US also has a really nice performance career, Halifax Middelsom, and he is competing and winning at 3rd level dressage now and will be moving up the levels soon (www.knabstruppers4usa.com)… Oh and btw, earlier this year, Altamont Sport Horses acquired Ambrosius af Asgard, aka Atlantis, so when you talk to them about Hollywood Hot Spot, you can chat about Atlantis also!
Then, of course, there are a few stallions out there that are appaloosa/warmblood crosses… and, Cloverlone Farm is certainly one place to look at for these horses…
So, trully, you have many stallions to consider… But first, I would decide if color is important, and if not, then you should probably start another thread about what stallions are competing in or producing offspring competing well in combined driving!
Good Luck and keep us posted!
