Compatibility of the tomato scions with wild brinjal rootstocks

The present study aimed to investigate the compatibility of tomato scions, namely, Kashi Anupam, Kashi Sharad, and Kashi Vishesh, with four wild brinjal rootstocks like S. torvum, S. violaceum, S. xanthocarpum, and S. incanum. Among the rootstocks, S. violaceum exhibited the shortest germination period at (17.17 days), with S. torvum taking 18.33 days to germinate after sowing, marking the highest day of germination. In the case of scions, Kashi Anupam showed the quickest germination at (9.33 days), while Kashi Vishesh took (11 days), displaying the highest germination percentage a S. torvum 79.83%. In contrast, Kashi Vishesh had a minimum germination percentage at 63.31%. The rootstock S. violaceum reached a graftable size in the shortest time at (41.99 days), while S. torvum took (49.17 days). Among the scions, Kashi Anupam achieved graftable size in (31.72 days), with Kashi Vishesh taking the least time at (29.77 days). The longest duration for graft union was observed in the combination of T 12 (S. incanum + Kashi Vishesh), requiring 8.14 days. Graft hardening took the maximum time in the combination of T 9 (S. xanthocarpum + Kashi Vishesh) scion, lasting (23.05 days). The grafting combination of T 1 (S. torvum + Kashi Anupam) exhibited higher graft success rates, minimal mortality, and the maximum survival percentage. The compatibility of the rootstock is crucial for the successful cultivation of grafted plants.
