Evaluation of brinjal and tomato scions for enhancing yield and quality attributes in grafted brimato plants

Urban Farm DB summary

Over three years (2019-2022) at ICAR-IIVR, Varanasi, India, researchers grafted four brinjal cultivars and three tomato cultivars as scions onto the vigorous, waterlogging- and salinity-tolerant brinjal rootstock IC 111056 to produce dual-fruiting 'Brimato' plants. The Kashi Manohar scion combined with Kashi Aman or Kashi Chayan gave the highest brinjal fruit numbers, while Kashi Aman combined with the Kashi Sandesh rootstock hybrid gave the highest tomato fruit numbers; the Kashi Sandesh + Kashi Chayan combination produced the highest total fruit yield at 2.58 kg/plant, and Kashi Aman + Kashi Sandesh reached a cumulative yield of 5.98 kg/plant. Photosynthetic rate and chlorophyll fluorescence varied significantly by scion, with Kashi Manohar and Kashi Aman showing the highest photosynthetic rates, and grafted plants showed higher vitamin C and β-carotene content.
