700 hr s=7.2°) for the mid-west at 900 to 1000 m elevation, and highly scab-resistant apple cultivars, having monogenic Vf, for el evations ^ 1200 m. Precocious fruiting, high productivity, high fruit quality, good storage capacity, red skin, and good mildew and bitter rot resistance are other important objectives of this project. From the results already obtained, 'Primicia', a precocious cultivar with Vf-scab resistance, high productivity, and red-skinned fruit, and 'Princesa', a low-chilling cultivar similar to 'Anna' possessing pre cociousness, high productivity, and good fruit flavor, crispness, firm texture, and red skin are the first two apple cultivars that were released at the end of 1986.
