Abstract
Aims: Evaluation of grafted tomato for resistance to Fusarium wilt under Telangana conditions.
Study Design: The poly bag experiment was laid out in Randomized Block Design (RBD).
Place and Duration of Study: The current experiment was conducted at College of Horticulture, Rajendranagar during Rabi, 2022.
Methodology: To find out the sources of resistance in grafted tomato for Fusarium wilt, three graft combinations i.e.T1 – Arka Vikas on Solanum torvum, T2 – Arka Vikas on Surya and T3 – Arka Vikas on Arka Keshav along with T4- Arka Vikas (Susceptible un grafted check) were screened under artificial inoculation conditions in poly bags.
Results: Among the four treatments, Fusarium wilt incidence ranging from 0 to 1 among three graft combinations such as T1 – Arka Vikas on Solanum torvum (0.00), T2 – Arka Vikas on Surya (1.00) and T3 – Arka Vikas on Arka Keshav (0.67) and (4.00) in T4 – Arka Vikas (Susceptible un grafted check). Among these T1 – Arka Vikas on Solanum torvum was showed highly resistance to Fusarium wilt with “0” score and the remaining graft combinations T2 – Arka Vikas on Surya and T3 – Arka Vikas on Arka Keshav was showed the resistance with the score values 1.00 and 0.67 respectively. Per cent of incidence was varied from 0% to 100%. The lowest per cent of incidence was recorded with the graft combination of T1 – Arka Vikas on Solanum torvum (recorded zero per cent incidence) and the highest per cent incidence was recorded in T4 – Arka Vikas (100% of incidence) where as T2 – Arka Vikas on Surya (25 % of incidence) and T3 – Arka Vikas on Arka Keshav (16.66% of incidence) respectively.
Conclusion: T1 – Arka Vikas on Solanum torvum was highly resistant to Fusarium oxysporum f. sp. lycopersici.
