Abstract
The experiment was conducted at Central Horticultural Experiment Station, ICAR- IIHR, Aiginia, Bhubaneswar, Odisha, India during kharif seasons of 2018 in collaboration with Odisha University of Agriculture and Technology, Bhubaneswar, to study the seed germination, days taken to reach grafting stage and grafting success (percentage) of rootstock and scion seeds used for grafting. The cultivated and wild species of brinjal and tomato were used as rootstocks with tomato Arka Rakshak F1 hybrid as scion. The experiment was conducted with 13 root stocks following statistical design CRD with three replications in pro trays to find out better root stock for grafting. A significant difference was recorded for the rootstock and scion parameters. Utkal Anushree had taken minimum number of days (6.67 days) for germination and the wild Solanum torvum had taken maximum number of days (16.67 days) to germinate, On the other hand, Arka Rakshak took least number of days (34.33 days) to reach grafting stage while the wild Solanum torvum reached to grafting stage within 56 days. The grafting success percentage ranged from 74.67 to 96 percent. Maximum grafting success (%) was recorded in Solanum torvum whereas minimum grafting success (%) was observed in S. sisymbriifolium wild solanum spp. root stock.
