ResumenPerformance of fruit species from Prunus is highly dependent on rootstock. This study focused on evaluating the field performance of several Prunus rootstocks in the main fruit irrigated production area in Tunisia. Nine new rootstocks: PADAC 150 AD, PADAC 04-03, PADAC 04-01, ROOTPAC 70, PAC 941, AP1, Krymsk-1, PAC 0301-04 and PM 105 AD were tested of comparison to the most widely used rootstock (Garnem). The performance of a flat nectarine variety ‘Subirana’ budded onto these rootstocks was evaluated. Phenological stages, rate of bud failure, vegetative growth and chlorophyll index were monitored. The results of the evaluated Prunus rootstocks revealed contrasting effects on the nectarine variety depending on the vigor of the rootstocks. The PADAC 04-03 induced an important vigor identical to that of trees on Garnem, whereas Krymsk-1 produced the lowest tree vigor. Krymsk-1 and PAC 941 induced an early development of floral buds, while the other rootstocks delayed flowering by few days. The nectarine variety ‘Subirana’ showed SPAD chlorophyll index values above the threshold with all rootstocks, which seems to have good nitrogen nutrition. PAC 0301-04 and Garnem obtained the highest yields.
