This paper identified the growth period，chlorophyll content，starch content and yield，etc．
biological characteristics of 17 Dutch varieties preserved in potato germplasm resources gene bank in China；and
obtained 3 varieties of medium early maturity，3 varieties of medium maturity，1 variety of medium late maturity
and 10 varieties of late maturity．Among them，‘Mentor’had the highest chlorophyll content and relatively high
starch content．‘Favorita’，‘Wilia’，‘Estima’and‘Bintje’had outstanding yields．‘Bintje’，‘Sirteme’，
‘Urgenta’and‘Dutch No.1’were highly resistant to potato scab．At the same time，3 superior potato varieties
