Jalene (also spelled Jalane or Jalenie) is an improved Ethiopian potato variety (Solanum tuberosum L.) released in 2002 by the Holetta Agricultural Research Center (HARC), Ethiopian Institute of Agricultural Research (EIAR). It was developed through the International Potato Center (CIP)–EIAR potato breeding program and became one of Ethiopia’s most influential improved potato varieties due to its high yield potential, early maturity, good cooking quality, and strong adaptation to highland production areas.
Jalene was widely adopted by Ethiopian farmers, particularly in high-altitude potato-growing regions, because of its good market acceptance, desirable tuber quality, and resistance to late blight at the time of release. The variety was considered an important improvement over many local cultivars and was commonly used as a standard check variety in Ethiopian potato research trials.
The variety performs well at elevations above 2,400 metres above sea level and matures in approximately 100–110 days. It produces white-skinned tubers with shallow eyes and is known for good dry matter content and excellent boiling quality. However, after many years of continuous cultivation, some studies reported increased late blight susceptibility in farmer fields, likely due to pathogen evolution and seed degeneration.
