Five years of high yield,with an average yield of 15 380 kg · hm^-2 during the peak fruiting period. Fruit soluble solids,total acidis and juice yield are 20.7%,9.66 g · kg^-1 and 66.00%,respectively.‘Zijing Meilu’exhibits strong cold resistance and high resistance to downy mildew. When cultivated in the open field in Changchun,its growth period ranges from 129-154 days.
