dc.description.abstractThe present investigation was conducted at Vegetable Research Farm, Department of Vegetable Science, Punjab Agricultural University, Ludhiana for “Imparting root knot nematode resistance through grafting in tomato (Solanum lycopersicum L.)” during Autumn season of 2015-2016 and 2016-17. The work plan was divided into three experiments based on different grafting methods which further divided into two different sites i.e. infested with root knot nematode and non-infested soil. Ten rootstocks with combination of two different scions (Punjab Sartaj and Punjab Ratta) were used as experiment material. For infested plots pure culture of nematodes were raised by taking galled roots of tomato plants from infested plots than galls were teased and freshly hatched second stage juveniles were raised and used for inoculums. It was observed that plant and fruit characters like plant height, fruit weight, harvest duration, marketable yield as well as total yield increased in grafted plants over nongrafted plants both in nematode free as well as Nematode infested plots. Further it was also revealed that plants grafted with Tube graft method observed highest success rate and was even responsible for earliness as well as high marketable yield in tomato plants. On evaluation of rootstocks plants grafted on EC-119197 recorded highest plant height, higher total and marketable yield, higher fruit weight and prolonged harvest duration both in Nematode infested and nematode free plots. Whereas plants grafted on rootstock PNR-7 recorded early flowering as well as early picking in infested plots. Rootstock L-097 recorded maximum fruit TSS while plants grafted on rootstock EC-119197 recorded maximum pericarp thickness. No significant effect was observed when grafted and non-grafted plants were examined for lycopene content. Overall rootstock EC-119197 can be used as a resistant rootstock against root knot nematode in addition it can fetch higher yield and better fruit quality.en_US
