Northern Dancer's male line reigns supreme

Email

Over the first decade of the 21st century the most obvious trend in North American Thoroughbred breeding was the steady rise of the male line of Mr. Prospector. From 2000 through 2010, male-line descendants of Mr. Prospector won 22 of the 33 American Triple Crown events and led the general sire list four times (depending on what countries you count).

As a result, Mr. Prospector’s male-line share of North American graded stakes winners increased from 16.1 percent in 2000 to 29.3 percent in 2010. Over that same decade, however, the male line of Northern Dancer, Mr. Prospector’s main rival in North America and the dominant male line in other parts of the world, maintained its lead, increasing its share of the graded stakes winner pool from 26.3 percent to 33 percent.

Those percentages remained stable in 2012. Through Dec. 26 and with just three graded stakes left to be run this year, 102 (29.3 percent) of the 348 North American graded stakes winners in 2012 trace in male line to Mr. Prospector, and 119 (34.2 percent) trace to Northern Dancer. If current trends extend for the next decade though, both Northern Dancer and Mr. Prospector better watch out for the new kid on the block.

In 2000, A.P. Indy was one of the country’s hot young stallions with six graded winners of his own that year, but too young to have successful sons at stud. By 2010, A.P. Indy, his sons, and grandsons accounted for 10 percent of North American graded stakes winners. In just two years’ time, that percentage jumped to 13 percent as the great son of Seattle Slew, his sons, and grandsons sired 45 graded winners compared to 36 two years ago.

As shown in the accompanying table of 2012 graded stakes winners by male line, no other sire line accounted for more than 10 percent of graded winners, with only Hail to Reason and In Reality contributing really viable numbers of winners. All other current male lines, some of which have made valuable contributions in recent years, hover around 3 percent or below of graded stakes winners.

This increasing concentration of America’s best racehorses in only a few male lines must be partly due to the dramatic change in book size that began around 1990, when modernized veterinary techniques and stallion management practices allowed stallion managers to double (or more) the number of mares popular stallions could cover. As a result, only about half the number of stallions now stand at stud in major breeding states compared with 20 years ago.

This heightened competition for a reduced number of places at stud inevitably reduces the opportunities for surprise success by stallions from less popular lines. Thus, success in graded stakes becomes a self-reinforcement loop leading to concentration on only the most successful and most fashionable male lines.

A.P. Indy retired near the beginning of the big book era and sired enough top-class sons early to get a foothold in Kentucky breeding sheds in the 21st century. It may be much more difficult for “outside” lines to increase their share of the pie in the future.

The Storm Cat branch of the Northern Dancer male line, in fact, provided more graded winners (49, 14.1 percent) than any male line other than those of Mr. Prospector and his grandsire, Northern Dancer. The Deputy Minister branch of Northern Dancer and the Fappiano and Gone West branches of Mr. Prospector each provided about 7 percent of the graded stakes winners.

Individual honors are more evenly divided among the most powerful lines. Four stallions, Ghostzapper (Northern Dancer), Pulpit (A.P. Indy), Smart Strike (Mr. Prospector), and Speightsown (Mr. Prospector) shared honors as leading sires of graded winners with eight apiece, while Bernardini (A.P. Indy) and Dynaformer (Hail to Reason) each sired seven.

The now deceased Dynaformer shared leadership by graded stakes wins with Empire Maker (Mr. Prospector) with 13. Ghostzapper revived his flagging stud career by siring winners of 12 graded stakes.

On the other hand, the leading individual winners of graded races all were male-line descendants of Northern Dancer. Game On Dude, Groupie Doll, Wise Dan, and Zagora all won five graded stakes in 2012.

Wise Dan's dam shined brightest

Only four broodmares − Lisa Danielle, Memories of Silver, More Than Pretty, and Oatsee − produced more than one graded stakes winner in 2012.

Lisa Danielle, dam of probable Horse of the Year Wise Dan, by Wiseman’s Ferry, also is dam of Grade 2 Alysheba Stakes winner Successful Dan, by Successful Appeal. The 18-year-old daughter of South African champion Wolf Power is odds on to win Broodmare of the Year honors.

While Lisa Danielle was only a maiden winner, Memories of Silver was a Grade 1 winner and More Than Pretty was a stakes winner. Memories of Silver is dam of Grade 1 winner Winter Memories, by El Prado, and Grade 3 winner La Cloche, by Ghostzapper. More Than Pretty is dam of Grade 2 winner Kauai Katie and Grade 3 winner Winding Way, both by Malibu Moon. Last year’s Broodmare of the Year, Oatsee, dam of Grade 1 winner Shackleford, by Forestry, and Grade 2 winner Afleeting Lady, by Afleet Alex, was stakes placed. All four are from well-established high-class families.
