The project was started in 1989 as a joint effort of Israel’s Agricultural Research Organization, the Volcani Center. The extensive research led by leading citrus breeders and botanists succeeded in developing an exceptional line-up of fantastic mandarin cultivars. The new cultivars were planted on experimental plots in Israel and the result was very successful: the Orri mandarin was born. The later crowned ‘King of Mandarins’ made its debut in early 2000 and quickly conquered the Israeli market. Despite the accelerated planting of orchards, consumers could not get enough and demand lagged supply. Year after year, the harvest continued to increase, and Orri conquered the Canadian, American and European markets.
