In cacti, grafting has become a commercial method of propagation to accelerate and hasten the growth rate of slow growing species, to ensure the survival of the plants with poor root system, to ensure the survival of genetic aberration of variegated and brightly coloured cacti that lack chlorophyll, to accelerate the growth of plants for commercial use. With the above futuristic background, the present study on ornamental cacti grafting with all possible combinations of two species of rootstocks (Hylocereus triangularis and Myrtillocactus geometrizans) and five species of scions (Mammillaria beneckei, Hamatocactus setispinu, Ferocactus latispinus, Echinopsis mamillosa and Gymnocalycium mihanovichii) was carried out during 2017-18 at the Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu, India to assess the compatibility of grafted ornamental cacti and its performance. Among the graft combinations, the success and survival percentage were found to be maximum in graft with Hylocereus triangularis as stock and Echinopsis mamillosa as scion (90 % and 100%) whereas it was maximum with Myrtillocactus geometrizans as stock and Hamatocactus setispinus as scion (96 % and 100%). The results of grafting studies indicated that the compatibility was found to be good when scions like Mammillaria beneckei and Echinopsis mamillosa are grafted onto Hylocereus triangularis whereas Hamatocactus setispinus and Mammillaria beneckei are suitable scions when Myrtillocactus geometrizans is used as rootstock.
