Abstract:: Taking Vitis amurensin ‘Xuelanhong’ as material,the effect of different cluster numbers per plant on quality and yield of ‘Xuelanhong’ were studied.The results showed that the yield，little green berries and total acid greatly increased，the clusters and berry weight and juice yield decreased with the increasing of cluster numbers per plant.Yield of each plant with 30 clusters was low，while yield was high with 90 clusters，but shoots were not fully mature as load capacity in late autumn，leading to the condition called ‘rest tree’ and a part of that plants dies in the next year.The output declined by 50.2%.Each plant retain experimental treatments，little green berries，sugar and acid content was suitable，production was moderate.Therefore，the suitable retain fruit was 50~70 clusters with two main vine trellis，spacing of 1.0 m×3.0 m.
