Of the stallions purchased from Crabbet, the best sire one was Naseem. Siglavi in type, Naseem was used for service at Tersk for 17 years until his death at the age of 31 in 1953. Overall, Naseem's progeny did not excel in jumping ability and lacked good quality of movement. The smallest in the group of Crabbet stallions, Naseem's measurements were 147, 174 and 18.5 cm. He generally sired horses of moderate height.
Born in 1922, Naseem was a son of Skowronek and out of Nasra. His contributions to breeding programs worldwide are significant. Acclaimed by Lady Wentworth as the best son of Skowronek, Naseem lived up to his reputation. In England in 1934, he sired Raktha, who in turn sired Silver Drift, Serafix, and Indian Magic.
At Tersk, Naseem sired 87 purebred foals including the champions Negativ and his full sister Nitochka. Nineteen of his daughters were retained for use at the stud. In addition to Nitochka (out of Taraszcza) the most valuable to the program were the mares Nagrada (out of Rixalina) and Naturalistka (out of Rissalma). Four of Naseem's sons were maintained in the Tersk program.
The most important Naseem son was Negativ. The line of Naseem is currently represented by descendants of this stallion.
