The results showed that the harvest period of tested varieties were 57~60 days，all were late-maturing varieties. Purple dragon 6, Purple dragon 8 and Black crown eggplant showed small differences in thickness, evenly colored and shiny with good commodity, fruit length were 41.5 cm, 39.4 cm and 36.4 cm respectively. The yield of Black crown eggplant was the highest (38 218.0 kg/hm2), Purple dragon 6 and Purple dragon 8 also had a high level yield.
