In 2002 and 2003 seasons, mature vines of Crimson seedless grapevines were pruned at the dormant season to leave 60, 90 and 120 buds per vine through changing the cane length to be 5, 10 and 15 budsfcane. Increasing vine load from 60 to 120 buds was accompanied with increase prunings weight, yieldfvine, number of clusters per vine, total acidity %, total carbohydrates in canes and reduction in the shoot length, leaf area, cluster weight, berry weight, berry size, berry dimension, berry firmness and berry adherence strength. Also, the high bud load caused decrease of total soluble solids%, as well as, TSSlacid ratio and total anthocyanin. All the studied parameters except yield and total acidity were tended to increase with raising vine load and the cane length. The highest yield with good quality of Crimson grapevines was obtained with bud load 90 buds per vine and cane length (10-15 budsfcane).
