When it comes to fruit crops, rootstocks are crucial in determining how productive orchards are. separate growth results can be obtained by budding or grafting two separate plants together that have complementary traits. This variance is apparent when taking into account the relative importance of rootstocks with respect to precocity, yield, and tree size control; additionally, variations in crop load, annual phenological cycles, fruit respiration patterns, and canopy management approaches are all taken into account. However, the impact of these factors on physiological, biochemical, and molecular aspects is still not fully comprehended. Rootstocks exert their influence on scion growth, vigor, and structure, as well as the precocity of the scion, flowering abundance, the likelihood of successful fruit set, and yield efficiency. The utilization of rootstocks in various fruit crops significantly impacts fruit crop production by influencing factors such as canopy structure, nutrient absorption, flowering, yield, and fruit quality (Rom et al., 1987). Moreover, rootstocks can also mitigate both biotic and abiotic stressors, including challenges related to soil pathogens, temperature extremes, salinity, and nutritional imbalances (Reddy et al., 2003). Rootstocks play a central role in determining the overall efficiency of orchards, encompassing responsibilities for water and mineral uptake and providing tree stability. They can provide some degree of tolerance to soils that may be overly moist or dry, and they are essential in regulating the size of trees. Studies and research on the selection and use of appropriate rootstocks in crops such as citrus, mango, and grapes have previously been carried out in a number of nations, with an emphasis on controlling growth vigor, nutrient absorption, soil salinity, moisture stress, and yield efficiency. India has yet to fully exploit the significant potential of rootstocks for many commercial fruit crops, and there is a need to identify rootstocks with optimal attributes that align with the specific environmental conditions in which the trees will be cultivated. This implies that a rootstock deemed most suitable for a particular variety and set of environmental conditions may not be the ideal choice for a different variety in a distinct environmental context (Nimbolkar et al., 2016). As such, comprehensive research on rootstocks for tropical and sub-tropical fruit crops becomes imperative.
