ABSTRACT
Avocado being an energetic fruit owing to its high nutritional value has gained global popularity. Its global production has witnessed a two-fold increase in the last decade. This scenario has led a pressure on avocado nursery production. Generally, avocado has been propagated through seed production that led to variability among off-spring and long juvenile period. Therefore, asexual propagation via grafting is the most appropriate method for producing high-quality, true to type plants. The current study was planned to evaluate four different grafting techniques (Cleft, Tongue, Patch and T-budding) in ten different cultivars of avocado. The outcomes suggested that Cleft grafting was most suitable one among all other evaluated techniques. The highest survival rate (27.40%) was recorded in cleft grafting. Moreover, vegetative characters, i.e., no. of leaves and leaf area, no. of internodes and internodal length, shoot length and diameter were also higher in cleft and tongue grafting as compared to other grafting method. Among cultivars, NARC-Feurte and NARC-Purple give the best outcomes.
