Abstract
Although conventional methods of vegetative propagation of cashew are-available, such as layering, patch-budding, side-grafting, veneer grafting and epicotyl grafting, which give varying degrees of success, these are not adequate to meet the large quantum of 8-10 million planting materials that are required for gap-filling, replanting and new planting in the country. Hence, there is an urgent need for supplementing these methods through tissue and meristem culture for: (a) generating more scion material for use in grafting, (b) obtaining rooted plants directly from elite trees, (c) developing an in vitro system for screening germplasm, hybrids, and other induced variability for resistance/ tolerance to diseases and pests, and (d) exploring possibility of inducing mutations of somaclonal variations for higher productivity and quality, as well as resistance/ tolerance to diseases, pests and stress environments. The potential applications of tissue culture in cashew improvement and some preliminary results obtained are discussed in this paper.
