Description

The set and growth of eggplant fruits can be improved by using pollinator insects or by treating flowers with phytohormones. These techniques can be costly and labor-intensive. Parthenocarpic cultivars offer the most cost-effective solution to improving fruit set and growth under suboptimal conditions. 'Anominori 2 go', a parthenocarpic eggplant cultivar developed at the NARO Institute of Vegetable and Tea Science in 2011, is an F_1 hybrid between two parthenocarpic inbred lines, 'AE-PO1' and 'AE-P24'. 'AE-PO1' was selected from a cross between 'Talina' (a commercial parthenocarpic F_1 hybrid that is widely grown in Italy) and 'Nasu Chukanbohon no 1 go' (a Japanese parental line). 'AE-P24' was developed from selective crossing of 'Nakate Shinkuro' (a Japanese traditional cultivar), 'Talina', 'Nasu Chukanbohon no 1 go', and 'Senryo nigo' (a commercial F_1 hybrid that is widely grown in Japan). 'Anominori 2 go' produces commercial yields without phytohormone treatment ; yields are higher than those of 'Anominori', another parthenocarpic cultivar developed at our institute.
