Interaction of scions and rootstocks against bacterial wilt, and grafting effects on plant growth and yield of brinjal (Solanum melongena L.)

The growth and yield traits of brinjal grafts, and their bacterial wilt resistance was differed significantly among the combinations of grafts. The maximum plant height, fruits per cluster, and fruits per graft [Arka Kusumakar (scion) and Solanum torvum (rootstock)] was recorded. The highest leaves per plant, number of branches, yield from a plant, and fruit yield of brinjal per hectare was witnessed from the grafts of scion Arka Kusumakar grafted on to the rootstock variety Surya. Surya and Solanum torvum as rootstocks exhibited superiority in brinjal growth and yield parameters. The scions Arka Kusumakar and PLR-2 plants grafted on rootstock Surya and S. torvum showed bacterial wilt resistance, and hence rootstocks would be suitable for the advancement of commercial grafting.
