Abstract

Grafting is an alternative approach used in vegetable production to fight against soil-borne diseases such as Fusarium wilt, bacterial wilt and nematodes since 1920s in Japan and Korea. Grafting as a technology for the commercial production was later on adopted by many countries in Europe, Middle East, Northern Africa, Central America and other parts of Asia. For the production of many fruit-bearing vegetables which include watermelon, cucumber, melon, tomato, eggplant and pepper, grafted seedlings were used. These seedlings besides providing resistance against biotic/abiotic stresses, increase the yield of the cultivars. This technique is considered eco-friendly for sustainable vegetable production because the resistant ischolar_mainstock reduces dependence on agrochemicals. Grafting improves quality of the plant and is used to induce resistance against low and high temperatures. Growth, yield and fruit quality of the scion is greatly influenced by the type of ischolar_mainstock used. Due to high post graft mortality of seedlings, this technology is still in infancy in India. For its commercial application in India, sharpening of grafting skills and healing environment need to be standardized.

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.
