“…The rootstocks 'Maxifort', 'DRO141TX', 'Fortamino', and 'Estamino' increased marketable yield compared with the nongrafted 'Tasti-Lee' plants. 'Maxifort' is a popular rootstock in the United States and has often been found to increase marketable yield in protected culture systems without significant pathogen pressure (Djidonou et al, 2017;Lang et al, 2020;Masterson et al, 2016;Meyer et al, 2021). Similar to our findings, Lang et al (2020) observed that 'Estamino' and 'DRO141TX' performed similarly to 'Maxifort' and increased marketable yield in high tunnel cultivation with the scion 'BHN 589'.…”

“…In the central United States, growers predominantly cultivate tomatoes in high tunnels. Vigorous rootstocks often have been used to increase marketable tomato yield in central U.S. high tunnel cultivation, where little to no disease pressure is evident (Lang et al, 2020;Loewen et al, 2020;Masterson et al, 2016;Meyer et al, 2021) 'Tasti-Lee' could offer high tunnel growers a high-value and unique product for marketing to consumers, restaurants, and other regional markets. Previous high tunnel trials in Kansas have found that grafting 'Tasti-Lee' to the rootstock 'Maxifort' can increase marketable yields by 59.5% more than nongrafted plants (Loewen et al, 2021).…”

“…For instance, the antioxidant capacity of 'BHN 589' tomato fruit increased when grafted to the rootstock 'RST-04-106-T', but the rootstock provided no yield benefit in high tunnel cultivation. In contrast, the higheryielding rootstock 'Maxifort' produced fruit with antioxidant capacity comparable to nongrafted plants (Meyer et al, 2021). The rootstocks selected for this study were chosen because their typical yield performance ranges.…”

“…'Maxifort' is an interspecific rootstock classified as having high vegetative vigor, and it often improves yield in high tunnels with low disease pressure (Loewen et al, 2020;Masterson et al, 2016;Meyer et al, 2021). 'DRO141TX' is also classified as a highly vigorous rootstock by seed companies, but it has less often been reported in the literature.…”

“…Preliminary data observed in Kansas showed that it increases yield with 'BHN 589' scion (Rivard, unpublished data). 'RST-04-106-T' was included because it typically does not provide yield benefits in high tunnel production, where little disease pressure is present (Lang and Nair, 2019;Meyer et al, 2021).…”

Grafting tomatoes with vigorous rootstocks can be used to increase yield in high tunnels without significant soilborne disease pressure. However, evidence suggests that grafting with high-yielding rootstocks could compromise the accumulation of primary and secondary metabolites. ‘Tasti Lee’ is a hybrid tomato that is bred to have a superior fresh-eating quality and higher lycopene content. The objective of this experiment was to investigate the yield and fruit quality impacts of grafting ‘Tasti Lee’ with rootstocks with ranging vigor and typical yield performance in high tunnels. Nongrafted ‘Tasti-Lee’ and ‘Tasti-Lee’ scion grafted onto ‘Maxifort’, ‘DRO141TX’, ‘Fortamino’, ‘Estamino’, and ‘RST-04-106-T’ rootstocks were trialed in a high tunnel in Kansas for three consecutive growing seasons (2018–20). The trials were arranged in a randomized complete block design with four replications. Total yield, marketable yield, average fruit size, and distribution of fruit size classes were assessed. Red ripe tomato fruit were harvested to determine the soluble solids content, titratable acidity, lycopene content, vitamin C content, antioxidant capacity, and fruit firmness. ‘Maxifort’, ‘DRO141TX’, ‘Estamino’, and ‘Fortamino’ significantly increased marketable yield (kg/plant) by 31.5% to 47.0% more than nongrafted plants. In contrast, ‘RST-04-106-T’ did not lend any significant yield benefit. Regardless of the rootstock, grafting increased the marketable average fruit weight by 20 g. Grafting did not have significant effects on any of the fruit quality attributes assessed. However, the soluble solids content of fruit from plants grafted to ‘RST-04-106-T’ was 10% higher (P < 0.05) than that grafted to ‘Maxifort’, indicating that rootstock genotype can influence this quality trait. Our findings suggest that growers can graft the tomato ‘Tasti-Lee’ with select vigorous rootstocks to increase marketable yield without sacrificing fruit quality for high tunnel production.

Tomato fruit quality is more strongly affected by scion type and planting season than by rootstock type

et al. 2022

Previous studies of tomato rootstock effects on fruit quality have yielded mixed results, and few attempts have been made to systematically examine the association between rootstock characteristics and tomato fruit quality. In this study, grape tomato (‘BHN 1022’) and beefsteak tomato (‘Skyway’) were grafted onto four rootstocks [‘Estamino’ (vigorous and “generative”), ‘DR0141TX’ (vigorous and “vegetative”), ‘RST-04-106-T’ (uncharacterized), and ‘SHIELD RZ F1 (61–802)’ (mid-vigor, uncharacterized)] and compared to non-grafted scion controls for two growing seasons (Spring and Fall in Florida) in organically managed high tunnels. In both seasons and for both scions, the two vigorous rootstocks, regardless of their designation as “vegetative” (‘DR0141TX’) or “generative” (‘Estamino’), exhibited negative impacts on dry matter content, soluble solids content (SSC), SSC/titratable acidity (TA), lycopene, and ascorbic acid contents. Similar effects on fruit dry matter content and SSC were also observed with the ‘RST-04-106-T’ rootstock, although little to no change was seen with grafting onto ‘SHIELD RZ F1 (61–802)’. Further studies are needed to elucidate the impact of rootstock vigor on tomato volatile profiles and consumer sensory acceptability in order to better determine whether any of the documented effects are of practical importance. On the other hand, the evident effects of scion cultivar and planting season on fruit quality were observed in most of the measurements. The scion by rootstock interaction affected fruit length, firmness, pH, and total phenolic content, while the planting season by rootstock interaction impacted fruit firmness, pH, total antioxidant capacity, and ascorbic acid and lycopene contents. The multivariate separation pattern of planting season, scion, and rootstock treatments as revealed by the canonical discriminant analysis further indicated that the influence of scion cultivar and planting season on tomato fruit quality could be much more pronounced than the rootstock effects. The fruit color (C* and H°), length and width, SSC, pH, total antioxidant capacity, ascorbic acid, and lycopene contents were the main attributes distinguishing different scion-planting season groups.
