Abstract
The cultivars Ori, Idit, Zohar, and Zahov have been bred specifically for adaptation to the Mediteranean climate: Ori and Idit are early tablestock cultivars, Idit is suited for “mini potatoes” (20 to 35 mm in diameter); Zohar is a midseason tablestock cultivai-, and Zahov is used as an early chipstock cultivar. The cultivars can be grown in either of the two main seasons in the Mediterranean region: the spring season (January through July) and the winter season (September through March). The cultivars have rapid emergence and early tuber set, they are tolerant to high temperatures and drought, and are not susceptible to external or internal defects. In field experiments, Idit yields were lower than the cultivar checks (Alpha, Nicola, or Desiree) in six of seven trials. However, the attractive appearance of the small oval tubers (20-35 mm in diameter) and the good aroma of the baked tubers are advantages. Yield of Ori and Zohar occasionally exceeded those of cultivar checks, and their yellowish skin, especially in sandy soils, is an advantage. Yields and tuber dry matter content of the early-maturing cultivar Zahov were similar to Hermes, a standard chipstock cultivar commonly used in Israel. The early maturation of Zahov is desirable to extend the harvest season.
Resumen
Los cultivares Ori, Idit, Zohar y Zahov han sido mejorados específicamente para adaptarse al clima del Mediterráneo: Ori e Idit son cultivares precoces para uso directo. Idit es usado como “mini papa” (20 a 35 mm de diámetro); Zohar es un cultivar de uso directo de media estación y Zahov es usado como un cultivar precoz para preparar hojuelas. Los cultivares crecen en cualquiera de las dos estaciones principales de la región mediterránea: primavera (de enero a julio) e invierno (desde setiembre hasta marzo). Los cultivares tienen rápida emergencia y tuberización temprana, son tolerantes a las altas temperaturas y sequias y no son susceptibles a defectos internos o externos. En experimentos de campo, los rendimientos de Idit fueron más bajos que los de cultivares testigos (Alpha, Nicola o Desirée) en seis de siete pruebas. Sin embargo, la apariencia atractiva de los pequeños tubérculos ovalados (20-35 mm de diámetro) y el rico aroma de los tubérculos horneados constituyen una clara ventaja. Los rendimientos de Ori y Zohar excedieron en ocasiones a los cultivares testigos y su piel amarillenta, especialmente en suelos arenosos, es igualmente una ventaja. Los rendimientos y contenido de materia seca de los tubérculos de maduración temprana del cultivar Zahov fueron similares a Hermes, un cultivar estándar para elaborar hojuelas, de uso común en Israel. La temprana maduración de Zahov es conveniente porque puede extenderse hasta la temporada de cosecha.
