Abstract: Different cultivars and seed-fruit reserving ways were investigated to improve seed yield and quality of eggplant. The results showed that the seed numbers per fruit produced by different fruiting layer was ranked as follows: the fifth, the fourth,the third and the second fruiting layer. Fruits on the second fruiting layer produced the best seed quality. The worst seed quality was in the fruits on the fifth fruiting layer.Fruits on the third and fourth fruiting layer produced intermediate seed quality. It could improve the seed quality of the third and fourth fruiting layer by controlling the reserving seed-fruit ways. The best way of reserving seed-fruit was 4 fruits on the third fruiting layer and 2 fruits on the fourth fruiting layer. In spite of all, the reserving seed-fruit was not higher than the fourth fruiting layer. Seed numbers per fruit was significantly difference among cultivars.It was important to select fruit with more seed as mother plant for seed production.
