She was sired by Roberto, an American-bred horse who won the Epsom Derby and the inaugural Benson and Hedges Gold Cup as a three-year-old in 1972.
At stud, Roberto sired many important winners including Sunshine Forever, Touching Wood, Real Shadai, At Talaq, Lear Fan, Kris S. and Dynaformer.
[2] After a break of almost ten weeks, Sookera returned for the Moyglare Stud Stakes at the Curragh in late August and was made the even money favourite.
On her final appearance of the season, Sookera was sent back to England for the Cheveley Park Stakes (then the only Group One race in Britain restricted to juvenile fillies) at Newmarket Racecourse in October.
Sookera took the lead a furlong out and looked likely to win easily but had to be pushed out by Swinburn in the closing stages to hold off Petty Purse and Fair Salinia by three quarters of a length and a head.
There was no International Classification of European two-year-olds in 1977: the official handicappers of Britain, Ireland and France compiled separate rankings for horses which competed in those countries.
