The problem of long juvenility, incompatibility and sterility are the biggest hindrances for the improvement of fruit crops through conventional fruit breeding. To mitigate the biotic and abiotic stresses, improvement is desired in already cultivated cultivar for one or few traits. In that regard, the biotechnological tools will prove quite useful to expedite the rate of fruit crop improvement. For production of quality planting material by tissue culture is commercialized in banana and strawberry. Biotechnological tools such as somaclonal variation and in vitro mutagenesis are the choicest method for varietal development in banana. GCTCV-119 and Novaria are the result of somaclonal variation and in vitro mutagenesis, respectively. Somatic hybridization has been explored for the rootstock and scion improvement of citrus. Somatic hybridization research of almost two decades in citrus is yielding fruit now. Embryo rescue has helped in accelerating the pace of stenospermocarpic grape improvement and ‘Sweet Scarlet’ and ‘Thomcord’ are two of the seedless table grapevines, which were released using this technique. Transgenic variety Rainbow and Sun Up carrying resistance to PRSV are being commercially cultivated in Hawaii of USA. With the introduction of concept of cisgenics, the genetically transformed fruits are likely to get public acceptance. Molecular marker aid great help in early diagnosis of sex of dioecious fruit plant like date palm and papaya. Presently marker linked to resistance for Dagger nematode and pierce disease at university of California in the breeding programs are routinely used for grapevine rootstock improvement. Genome sequencing has unveiled the mystery about various genes, the phylogenetic relationship and evolution history of sequenced fruit crop.
