摘　　要：试验测定了树莓不同品系果实产量,并对与货架期相关的果实品质及主要性状进行了相关性分析。结果表明,SJR941-18,SJR941-1和SJR944-2是果实较大的品种。Boyne,Festival,Killarney和SJR941-5茎的耐寒性显著优于其他品种,使这些品种有较高的产量。树莓果实产量与茎的活力和健康花芽数呈显著正相关,与死亡茎长度呈显著负相关。茎的活力与健康花芽数、健康茎长度呈显著正相关。果实硬度和可溶物含量、果实表面绒毛多少与解冻后果汁百分比亦有显著相关性。<Abstrcat> In the experiment fruit output of various red raspberries were tested and the relationship between fruit quality and important features were analysied.The results show that SJR941-18, SJR941-1 and SJR944-2 have large fruit size and cold hardness of Boyne, Festival, Killarney and SJR941-5 were significantly higher to Nova and other selections,which results in these cultivars higher output than the other varieties. Fruit yield and cane vigor after winter had a significant correlation. The control cultivars and SJR941-5 grew vigorously after the cold winter and can be considered to be damaged significantly less. Fruit yield was also significantly correlated with the number of the healthy buds; it was minus significantly correlated with the dead length of the canes. Vigour of the cane was significantly correlated with the healthy buds and healthy length. Fruit firmness was significantly correlated with soluble solid content, the fruit hairiness and juice percentage after thaw.
