Abiotic stressors are increasing gradually due to climate change. Among abiotic stresses, drought is a difficult constraint in confined cultivation. The advancement in molecular tools has increased fruit productivity via hybridization. Because of the greater heterozygosity, pollination phenomenon, and long juvenile era, conventional breeding has had poor accomplishment. The utilization of contemporary molecular methods can aid in the development of hybrid fruit crops, particularly Indian jujube, for required traits. Genetic manipulation and gene transfer have had a greater potential to increase genomic uniqueness in fruit crops by introducing new genes. Even so, the random integration of foreign DNA into the genome of a fruit tree results in transgene silencing. Gene editing is an important method for modifying the genome of fruit trees at specific sites, which is an appealing primary objective for fruit tree breeders. The present study is focused on fruit tree breeding through the use of exact molecular strategies. Genome editing tools are extensively used in genetic modification to enhance tolerance to abiotic stresses in a diverse array of horticultural crops. However, its implications in underutilized fruit crops remain limited. Jujube is an underutilized/minor fruit crop with significant health benefits, particularly in terms of ascorbic acid. Breeding wild and domesticated landraces on the basis of modern molecular methods is required to improve tolerance to drought.
