Selection criteria included fruit colour, taste, size, maturity date, storage life and firmness and tree growth habit, precocity and productivity. 'Golden Sentinel' was given the experimental designation 8C-39-69 in 1998 and propagated on Malling 26 rootstock in 1989. Evaluation of the variety occurred between 1987 and 1995.
