Who knows where or when the next ‘unexpected’ great horse will arrive, but doing your homework definitely helps. Research done well beyond five generations, gives a much fuller picture regarding the genetic buildup behind the scenes, and the kind of genes that are ready for expression.
There are certain individuals who exhibit specific talent and conformation. We can select for these traits easily enough. However, in addition to selecting individuals, inbreeding and line breeding, there are certain ‘combinations’ of horses that consistently produce successful offspring. This is called a ‘nick’. A nick can produce the unusual. One of the most explosive nicks in Thoroughbred history was that of Lexington when crossed with a daughter of Glencoe.
The brilliant sprint mare Nogara descended directly from the Lexington/Glencoe stakes winning mare Maiden. Nogara was the dam of one of the most prominent horses of modern Thoroughbreds: Nearco. Bred by the ‘wizard of Dormello’ Frederico Tesio, Nearco, was an undefeated racehorse, and essentially a modern Foundation horse for many brilliant stallions, mares and their descendants. One of the tenants of Tesio was: bring the stallion’s dam back to him. The mating that produced the famous ‘Nasrullah’ essentially did that.

Nearco (out of Nogara who was a tail-female descendant of a Lexington/Glencoe daughter) was bred to Mumtaz Begum who brought in another direct female line to the almighty Lexington/Glencoe nick in a powerful way. [Note: Mumtaz Begum was a half sister to Mah Mahal, dam of a known large heart sire 'Mahmoud'. Both Mumtaz Begum and Mah Mahal sprung from the loins of Mumtaz Mahal, thought to be the fastest filly of all time, and a mare that had a significant impact in 20th century breeding.] Mumtaz Begum’s tail-female great grand dam was Americus Girl who was by Americus; a highly inbred horse. Americus’ grandsire ‘Norfolk’ was by Lexington out of the Glencoe daughter Novice. Americus’ grand dam ‘The Nun’ was by Lexington, also out of the Glencoe daughter Novice. So, his paternal grandsire, and his maternal grand dam were full siblings. It is worth noting that another Glencoe daughter, ‘Charmer’ is a tail-female ancestress to Americus’ sire, ‘Emperor of Norfolk’.
[Please see speed and large heart analysis of Americus]
A large dose of the super-nick in Mumtaz Begum’s heritage was brought to Nearco, and produced the legendary super sire Nasrullah.
As a two year old, Nasrullah won the Coventry Stakes, and the Great Bradley Stakes. He came in second at the Middle Park Stakes. At 3, he won the Chatteris Stakes, the Cavenham Stakes and the Champion Stakes. He was third in the Derby Stakes. All in England. He was Champion Two Year Old Colt again in England in 1942. He was also Leading Sire in England in 1951.
He was brought to the USA in 1949, and was Leading Sire in America in 1955, 1956, 1959, and 1960.

Champion Older Horse in 1972.
A significant presence of the most notable nick of all time — Lexington/Glencoe – had been inadvertently accumulated. How could it have gotten even better?
Waiting in the wings; enter the lovely and talented ‘Miss Disco’. Miss Disco herself was a successful racehorse, running in 54 races, and placing in the top three, 23 times. She earned over $80,000 in the ‘1940’s. She plays a double role in this article, one of introducing her sire, Discovery, and two: demonstrating the amazing power of adding more ‘Tabasco’ to the all ready spiced up Nasrullah.
Miss Disco was a marvelous combination of American and English Thoroughbred blood, much of which has added up to extraordinary performance. It is not a coincidence that her great grand sire was none other than Fair Play, the sire of Man O’ War. That’s just for starters. There was an injection of the Lexington/Glencoe nick through Man O’ War’s great grandsire Spendthrift. But looking at Miss Disco’s sire, Discovery**, we uncover the real gold.
Champion Handicap Horse 1936, and known as the “Iron Horse”, Discovery’s weight carrying record sets the standard for all who follow. He stood 16.1 hh, was a gentleman, and an amazing horse. Those who knew him were impressed by his manners, the perfect demeanor for an exceptional horse.
Discovery’s strength at stud was through his daughters. He carried an extraordinary amount of X (large heart) blood in his veins, which seemed to determine his fate as a broodmare sire. Discovery gets a big Lexington/Glencoe boost through his dam, Ariadne who inherits from the brilliant Hamburg, and another horse named His Majesty. Discovery’s tally of Lexington comes to 6 crosses, and of those 6, 2 are Lexington/Glencoe nicks, and those two are wonderfully placed in x positions. In addition to the Lexington, Lexington/Glencoe nicks, Discovery racks up a STAGGERING amount of additional Glencoe crosses. 42 of them. Of the 42, 7 are daughters in x-positions.
Miss Disco’s dam, Outdone, had her own genetic treasure trove. Outdone added 9 crosses to Lexington, and of those 9, 4 are Lexington/Glencoe nicks. Of those 4 nicks, 2 are in x-positions, one being tail-female to Sweep On, Outdone’s broodmare sire. The success of Miss Disco both as a racehorse, and as a broodmare, should therefore come as no surprise at all.
Discovery also sired:
Geisha 1943. The dam of Native Dancer who won over $785,000, including the Preakness Stakes, the Wood Memorial, the Belmont Stakes, the Withers Stakes, Travers Stakes, the Metropolitan Handicap, to mention just a few. He was one of the most dominant sires of the mid to late 1900s, and was the broodmare sire of Northern Dancer, and grandsire of Mr. Prospector.
Traffic Court 1938 1954 Broodmare of the Year, winner of over $50,000, and the dam of USA Champion 2 year old colt, Hasty Road. Hasty Road set a national Track Record in the 1954 Derby Trial at Churchill downs, one mile in 1:34:00. He won over $541,000, which included the Preakness Stakes, 2nd in the Kentucky Derby.
GoodThing 1941 the dam of Bed o’ Roses who won over $383,000. Bed o’ Roses awards include: Champion Two Year Old Filly of 1949, Champion handicap mare of 1951, at 3 she turned out a national Track Record at Santa Anita Park, for the distance of 7/8 of a mile in 1:21.3. Hall Of Fame Inductee, 1976.
When all of these elements are combined, and Miss Disco, the 1958 Broodmare of the Year, was brought to Nasrullah, we get another brilliant individual: Bold Ruler**. When Bold Ruler, collector of the most explosive nick in the history of Thoroughbreds, a collector of additional Glencoe, and a collector of Hermit blood met up with Somethingroyal, who brought a very high concentration of Glencoe, and Hermit blood, the result was the incomparable Secretariat. We haven’t seen anything like him since.
Buildup of ’special combinations’ in pedigrees is like adding more and more spice to a recipe, without causing it to degrade. I am not sure that Secretariat could have been crossed with any mare of the time, who had an equal measure, or even more of what he had. Thoroughbred breeding had reached a pinnacle of sorts.
Genes represent only about 35% of your work. The rest is the environment: nutrition, proper management, routine excellent care, and a keen attention to the details. The physical, emotional, psychological environment that is provided for the mare directly affects the foal, in uterus, and out. This is what truly needs consideration to allow the best potential expression of those very carefully chosen gene combinations.
