Quarter Horse Mares

Mare and foal, 6666 Ranch.

Much of our success rests squarely with our band of exemplary broodmares. Our Quarter Horse mare families have produced All-American Futurity Winners, Leading Money Winners, World Champions in a wide variety of performance events, NCHA and NRHA winners, and more.

Here we introduce these grand matriarchal lines and share our broodmare selection criteria. You also may check out the latest news for more on their offspring. Enjoy photos on the stallions pages, and look over our sale horses for more proof of the feminine contribution.

Mare Families

Over the past 100 years or so, certain “mare families” have proven to deliver desirable traits in their offspring. The Four Sixes has always focused on producing the best possible ranch horses, and, in more recent years, successful arena performance and race horses, as well.

The predominant 6666 mare families are identified by number, the most important of which include: 99 (our most dominant line), 96, 59, 4, 23 and Triangle 29 (V29). The unique traits of each are taken into consideration when breeding decisions are made each year.

Some ranch-type mares from time to time are crossed with racebred stallions, as we recognize the historic influence of Thoroughbred lines in a good breeding program. The resulting offspring often make excellent performance horse prospects in several disciplines, including various cattle classes, roping and barrel racing – as well as good breeding stock.

6666 Broodmare Selection Criteria

The decision to retain a broodmare is based on the following:
