Grafting is increasingly becoming an indispensable tool that minimizes the risks associated
with intensive vegetable production systems, including soil-borne diseases. This study assesses the
performance of two cherry tomato hybrids (‘Cheramy’ and ‘Sheeja’) grafted onto three tomato and
five eggplant local rootstock genotypes (cultivated/wild) under Ralstonia solanacearum (bacterial
wilt)-infested greenhouse soil. The impact of grafting on growth, yield and fruit physical quality
was mainly influenced by the response of rootstocks to disease resistance. The non-grafted plants
of both the cultivars were severely affected by bacterial wilt, thus presenting high susceptibility to
disease. Eggplant rootstocks imparted moderate to high resistance against bacterial wilt in both
the scions, while tomato (cultivated or wild) rootstocks did not improve disease resistance, except
‘Anagha’, which provided resistance to scion cv. ‘Cheramy’. In general, scion cv. ‘Cheramy’, grafted
or non-grafted, showed superior growth, yield and fruit quality compared to ‘Sheeja’. The most
productive graft combinations for both the cultivars involved resistant rootstocks, i.e., ‘Sheeja’ onto
eggplant rootstock ‘Surya’, and ‘Cheramy’ onto tomato rootstock ‘Anagha’. Fruit quality attributes
such as ascorbic acid and lycopene contents were considerably higher, and the total soluble solids
(TSS) content was considerably lower in scion cv. ‘Cheramy’, whether grafted or non-grafted, than
those involving scion cv. ‘Sheeja’. The grafting effect on fruit chemical quality attributes was not
promising, except grafting ‘Sheeja’ onto ‘Sopim’ for TSS, ‘Sheeja’ onto ‘Sotor’ for lycopene and
‘Cheramy’ onto ‘Ponny’ for total phenols, though no clear connection with disease incidence was
in these grafts. Conclusively, eggplant rootstock imparted wilt resistance, while both eggplant and
tomato rootstock grafting was beneficial to both scion cultivars in boosting the overall production
and economic gains, especially for ‘Cheramy’ grafted onto ‘Anagha’ rootstock under bacterial wilt
infested soil of greenhouse.
