Morpho‐Physiochemical Characterization of Grafting Compatibility Among Jackfruit ( <i>Artocarpus heterophyllus</i> L.) and Its Wild Relatives

Jackfruit ( Artocarpus heterophyllus ) is a nutritionally and economically important tropical fruit crop but poor tolerance to abiotic stress constrained its cultivation. Hence, interspecific grafting with stress‐resilient wild relatives would be a sustainable strategy to overcome it. In this study, nine reciprocal graft combinations among A. heterophyllus (jackfruit) and its wild relatives of A. lacucha (“dewa”), and A. chama (“chama kathal”) were evaluated to sort out efficient rootstock and scion after assessing graft compatibility following early‐stage phenotyping and biochemical profiling characterization. Results revealed that among the studied jackfruit wild relatives, dewa was found as effective rootstock for grafting with the scion of jackfruit that showed the highest number of leaves (16.2), branches (2.3), maximum carotenoid content (82.57 mg/g), and…
