The new variety Qinyu 32 （the original code： Kang 0102-5） was derived from a cross made in 2000 using Qinyu 30 as female and Qinyu 89-1, a selection line, as male parent, which was selected out in breeding nursery and appraisal nursery.

This variety was multiplied and tested in the national regional trials of Southwest Group in middle-late maturity class in 2007-2009, and tested in National production trials in 2010, giving a average yield of 1443 kg/667m^2, with a 12.5% increasing compared with the control variety Mira. The tuber dry matter content was 18.5%, starch 11.8%, vitamin C 14.2 mg/100 g, crude protein 2.1%, and reducing sugar 0.29%. Disease resistance evaluation showed that it was resistant to late blight, moderately resistant to PVX and PVY.
