An inter-specific tomato-potato graft study was undertaken in a naturally ventilated quonset polyhouse at Palampur during the autumn and winter seasons 2015. The treatments comprised of combination of two tomato hybrids [Avtar-7711 (S1) and GS-600 (S2)] as scions, three potato cultivars viz. Kufri Himsona (V1), Kufri Himalini (V2) and Kufri Giriraj (V3) as ischolar_mainstocks and two grafting methods viz. tongue grafting (G1) and cleft grafting (G2). GS-600 tongue grafted on Kufri Himalini (V2G1S2) resulted in maximum survival of grafted plants (93.25%) as well as grafting success rate (81.68%). Kufri Himalini (V2) was found to be the best ischolar_mainstock for tomato scions which gave 2 maximum survival of grafted plants (87.89%) as well as grafting success rate (76.59%). Cleft grafting (G2) resulted in maximum survival of grafted plants (84.13%) and grafting success rate (72.95%). Tomato scion GS-600 (S2) was found to be the best scion for potato ischolar_mainstocks which resulted in a significantly higher survival of grafted plants (85.72%) and grafting success rate (73.85%) as well. Kufri Himalini+GS- 600 was the best ischolar_mainstock-scion combination giving maximum survival of grafted plants and grafting success rate irrespective of the grafting methods used. It is also concluded from the study that irrespective of the ischolar_mainstocks and grafting methods employed, scion GS-600 (S2 always had better survival in grafted plants and a significantly higher grafting success rate at least for the three best performing treatments and grafting tomato on potato plants in compatible combinations had a significant impact on their survival.

Abstract


An inter-specific tomato-potato graft study was undertaken in a naturally ventilated quonset polyhouse at Palampur during the autumn and winter seasons 2015. The treatments comprised of combination of two tomato hybrids [Avtar-7711 (S1) and GS-600 (S2)] as scions, three potato cultivars viz. Kufri Himsona (V1), Kufri Himalini (V2) and Kufri Giriraj (V3) as ischolar_mainstocks and two grafting methods viz. tongue grafting (G1) and cleft grafting (G2). GS-600 tongue grafted on Kufri Himalini (V2G1S2) resulted in maximum survival of grafted plants (93.25%) as well as grafting success rate (81.68%). Kufri Himalini (V2) was found to be the best ischolar_mainstock for tomato scions which gave 2 maximum survival of grafted plants (87.89%) as well as grafting success rate (76.59%). Cleft grafting (G2) resulted in maximum survival of grafted plants (84.13%) and grafting success rate (72.95%). Tomato scion GS-600 (S2) was found to be the best scion for potato ischolar_mainstocks which resulted in a significantly higher survival of grafted plants (85.72%) and grafting success rate (73.85%) as well. Kufri Himalini+GS- 600 was the best ischolar_mainstock-scion combination giving maximum survival of grafted plants and grafting success rate irrespective of the grafting methods used. It is also concluded from the study that irrespective of the ischolar_mainstocks and grafting methods employed, scion GS-600 (S2 always had better survival in grafted plants and a significantly higher grafting success rate at least for the three best performing treatments and grafting tomato on potato plants in compatible combinations had a significant impact on their survival.
