Tomato grafting is an important agricultural technique to overcome biotic and abiotic stresses and increase plant growth and productivity. Breeding and selection of resistant and vigorous rootstocks are necessary to achieve grafting goals. Therefore, this study was conducted to evaluate eight tomato interspecific hybrids between accession Solanum lycopersicum L. LA1221 ‘VFNT cherry’, as the female parent and each of wild accessions S. chmielewskii LA1028 (Chm-1028); S. galapagense LA0530 (Gal-530); S. habrochaites CGN 15391 (Habr-15391) and LA1777 (Habr-1777); S. pennellii AusTRCF 312075 (Pen-312075) and LA716 (Pen-716); and S. pimpinellifolum AusTRCF311810 (Pim-311810) and CGN18388 (Pim-18388), as male parents, as rootstocks under greenhouse conditions compared to the commercial rootstock ‘Emperador’, to select the most suitable rootstock. S. lycopersicum ‘Santa Cruz Piedade’ was selected as a scion and used as self-grafted and non-grafted controls. Plant growth and productivity measurements were estimated for the grafted and non-grafted plants. The response to the evaluated rootstocks was not consistent for many of the studied traits, denoting that the scion was differently influenced by the rootstocks. Grafts did not always outperform self-grafts. Grafting onto either Pen-312075, Habr-15391, or Pim-18388. in addition to self-grafting, increased the total and marketable yields compared to the non-grafted plants, with proportions that would enable increased profits and cover the extra cost of grafting. In addition, fruits from these grafts had acceptable quality traits. Therefore, the interspecific hybrids Pen-312075, Habr-15391, and Pim-18388 are considered suitable rootstocks to improve the scion ‘Santa Cruz Piedade’. Greater and continuing efforts are needed to evaluate several interspecific hybrids, as well as different high yielding scion cultivars, to select the most suitable rootstocks for different scion cultivars.

番茄嫁接是克服生物和非生物胁迫并提高植物生长和生产力的重要农业技术。为了实现嫁接目标，必须对耐性强的砧木进行选育和选择。因此，进行了这项研究以评估作为雌性亲本的番茄Solanum lycopersicum L. LA1221'VFNT cherry'和野生种S. chmielewskii LA1028（Chm-1028）之间的八个番茄种间杂种。S. galapagense LA0530（加-530）; S. habrochaites CGN 15391（Habr-15391）和LA1777（Habr-1777）; 潘那利番茄S. AusTRCF 312075（笔312075）和LA716（笔-716）; 和S. pimpinellifolum与商业砧木“ Emperador”相比，AusTRCF311810（Pim-311810）和CGN18388（Pim-18388）作为雄性亲本在温室条件下作为砧木，可以选择最合适的砧木。番茄'Santa Cruz Piedade'被选为接穗，并用作自移植和非移植对照。估计了嫁接植物和非嫁接植物的植物生长和生产力测量值。在许多研究的性状中，对评价的砧木的反应不一致，这表明接穗受砧木的影响不同。嫁接并不总是优于自移植。嫁接到Pen-312075，Habr-15391或Pim-18388上。除了自嫁接外，与未嫁接的植物相比，总产量和可销售的产量都有所提高，其比例将使利润增加并支付嫁接的额外成本。此外，这些嫁接的果实具有可接受的品质性状。因此，种间杂种Pen-312075，Habr-15391，Pim-18388和Pim-18388被认为是改良接穗'Santa Cruz Piedade'的合适砧木。需要作出更大的持续努力来评估几种种间杂种以及不同的高产接穗品种，以便为不同接穗品种选择最合适的砧木。
