Abstract

Grafting of fruiting vegetables is an effective technique to overcome pests and diseases in modern croppingsystems and it is often used to improve yield and fruit quality. Eggplant is an important vegetable crop thatbenefits significantly from grafting. In this regards, the exploitation, valorization and breeding of new rootstockgenotypes as possible substitute to those commonly used (Solanum torvum and tomato hybrids) would permit anintensive eggplant crop system in those situations where a rootstock rotation is required. In the present article,we study the effects of several potential rootstocks including both wild/allied species of eggplant [S. torvum(STO), S. macrocarpon (SMA), S. aethiopicum (accession SASI), S. aethiopicum (accession SASa2), S. paniculatum(jurubeba) (SPA) and S. indicum (SIN)] and Msa 2/2 E7 and 460 CAL. eggplant hybrids on plant vigor, yield andfruit characteristics of eggplant F1 hybrid (‘Birgah’), in two spring-summer growing seasons (2014 and 2015).SPA and the hybrids Msa 2/2 E7 and 460 CAL. displayed a high percentage of grafting success. ‘Birgah’ sciongrafted onto the two above-mentioned rootstocks showed a notable vigour and yield. Both rootstocks did notpromote any unfavorable effects on apparent fruit quality traits and overall fruit composition. Furthermore, theconcentration of glycoalkaloids in the fruit remained below the recommended safety value (200 mg/100 g ofdw). These results suggest that SPA and Msa 2/2 E7 and 460 CAL. eggplant hybrids might represent a potentialrootstock alternative to S. torvum.
