**2. Materials and Methods**

This experimental study was conducted during the crop season of 2017 and 2018 at Floriculture Research Station, University of Agriculture, Faisalabad to evaluate the compatibility and suitability of grafting techniques for hybrid cucumber cv. Kalaam F1 scion grafted onto four local cucurbitaceous rootstocks (Pumpkin, Ridge gourd, Bottle Gourd and Bitter gourd) under greenhouse conditions (Temperature 28 ◦C and 90% humidity). Screening and determining the resistant and tolerant rootstock against soil pathogenic characteristics were performed.

#### *2.1. Grafting Plant Materials*
