This study was conducted in two successive seasons 2021 and 2022 to evaluate mature trees of African-rose and Pioneer plum cultivars grafted on Nemagard rootstock. Evaluation parameters included vegetative measurements (shoot length, shoot diameter, umber of leaves and leaf area) and flowering measurements (dates of bud burst, onset of flowering, full bloom, end of flowering and onset of fruit set), fruiting attributes, yield, date of fruit maturity and fruit quality. The obtained data showed that African-rose plum cv. superior to Pioneer cv. in earlier of bud burst dates, onset of flowering, full bloom, end of flowering and onset of fruit set, the highest in initial and final fruit set percentage, as well as shoot length, number of leaves leaf area and less fruit drop percentage. While pioneer cv. gave a high yield and an increase in weight, volume, height, diameter fruit and earlier in fruit maturity about four to seven days and an increase in TSS %, total and reducing sugars percentage and decrease in total acidity percentage as compared with African-rose plum cultivar. It could be concluded that Pioneer plum cultivar are considered as promising cultivar under sandy soil conditions in Assiut due to their recently, high yield and early fruit ripening and fruit quality, randomized complete block design (RCBD) was followed in data analysis.
