(PRI 673-20 = tetraploid 'Golden Delicious' x PRI 14-152) Introduced as 'Sir Prize' (Williams et al. 1975) U.S. Plant Patent No. 3,988
- Fruit: 70 to 76 mm or more (2-3/4 to 3+ in.); short conic to long conic with calyx points; bright finish, 100% green yellow to lemon yellow with an occasional slight red blush; fine grained, lemon yellow colored crisp yet very tender flesh; moderately to spritely acid, and rich in flavor with distinctive aroma; very juicy; very good dessert quality. Large fruit size. Smooth, conic shaped, very attractive fruit with limited russet. Annual cropping. Retains quality for 6 months in refrigerated storage. Fruit hangs on the tree very well.
- Season of Maturity: With 'Delicious'.
- Tree: Vigorous, spreading growth habit, moderately spurry, 90 degree crotch angles, moderately large size tree.
- Disease Resistance: Field immune to apple scab; good level of resistance to powdery mildew; moderately susceptible to cedar-apple rust; susceptible to fire blight.
- Problems: Tender (yet crisp) flesh is extremely sensitive to bruising, which makes it unacceptable as a commercial cultivar, although fruit size, finish, and fine quality make it ideal for the home garden; susceptibility to cedar-apple rust is a problem in some areas; susceptibility to fire blight is a problem in some areas; triploid with unviable pollen so it requires an additional pollinizer.
- General Recommendation: Suggested for limited use in pick-your-own operations and as a home grower cultivar. 'Sir Prize' is currently the only widely available, yellow scab resist-ant apple in 'Golden Delicious' season.
