The Bapatla technique of soft-wood grafting on 35-45 days old root stock retained with one pair of leaves was observed with greater percentage of success during December and January for the regions of coastal Andhra Pradesh. This technique gave good graft-take with a high percentage of scion sprouting with good growth of grafts having maximum plant height, number of leaves and maximum leaf area per graft during all the months except during March when compared to normally adopted methods of vegetative propagation for multiplication of cashew in India. The vigourous rootstocks of commercial giant and dwarf cultivars as well as hybrids developed at cashew research station of Bapatla in Andhra Pradesh may be useful for identification and development of dwarfing rootstocks in cashew for high productivity, suitability to high density planting and adoptability to diverse agroclimatic conditions of India. The presented germplasm of high yielding cultivars, dwarf cultivars and hybrids are a valuable resource i) to study the reproductive biology of cashew ii) develop cultivars with high percentage of hermaphrodite flowers iii) to produce scions with prolific yields iv) to improve national income from export earnings of cashew nuts and v) to sustain the quality standards and international market. Physiological studies on the potential rootstocks of cashew is the present research need.
