Grafting is regarded as an integral component of sustainable vegetable production. It is important in the management of soil-borne diseases, and reports suggest that grafting with viable rootstocks can enhance crop growth and yield. This research was conducted using splices and cleft grafting techniques to investigate graft compatibility among varieties of high yielding eggplant scion (MCV1, MCV2, CCV1, CCV2, CCV3, NCV, and TCV) grafted onto wild rootstocks (MWR, BWR, and TWR) to study their morphophysiological and yield characteristics. High yielding scions grafted onto wild relative rootstocks were compared with two controls including self-grafted and non-grafted. All the scion had a high rate of germination (≥95%) and remarkable graft success (100%) was recorded in MCV1, MCV2, and TCV using the cleft techniques. Generally, the use of rootstocks resulted in higher total and marketable fruit yield compared to the non-grafted and self-grafted scion plants, respectively. In particular, MWR and TWR rootstock conferred the highest vigour to the scion, resulting in the highest values recorded for total and marketable fruit yield, number of fruits per plant and average fruit weight. A similar result was obtained in fruit length and diameter, where long and wide fruits were observed in scions grafted onto MWR and TWR rootstocks, respectively. Grafting of high yielding eggplant scion onto resistant MWR, BWR and TWR eggplant rootstock was found to be beneficial for eggplant cultivation. The remarkable compatibility and vigour of the rootstock with scion led to the improvement in total and marketable yield of the fruits. As such, it can be concluded that the use of wild relative rootstocks of eggplant species can be a valuable method of improving eggplant production.
嫁接被视为可持续蔬菜生产的一个重要组成部分。它在土传病害管理中很重要，并且报告表明用有活力的砧木进行嫁接可以促进作物生长和提高产量。本研究采用劈接和切接技术，研究高产茄子接穗品种（MCV1、MCV2、CCV1、CCV2、CCV3、NCV和TCV）嫁接到野生砧木（MWR、BWR和TWR）上的嫁接亲和性，以研究它们的形态生理和产量特征。将嫁接到野生近缘砧木上的高产接穗与包括自嫁接和未嫁接在内的两个对照进行比较。所有接穗的发芽率都很高（≥95%），使用切接技术时，MCV1、MCV2和TCV的嫁接成功率达到了显著的100%。一般来说，与未嫁接和自嫁接的接穗植株相比，使用砧木分别使总产量和可销售果实产量更高。特别是，MWR和TWR砧木赋予接穗最高的活力，导致总产量、可销售果实产量、单株果实数量和平均果实重量达到最高值。在果实长度和直径方面也得到了类似的结果，嫁接到MWR和TWR砧木上的接穗分别长出了长而宽的果实。将高产茄子接穗嫁接到抗性MWR、BWR和TWR茄子砧木上被发现对茄子种植有益。砧木与接穗显著的亲和性和活力导致果实总产量和可销售产量得到提高。因此，可以得出结论，使用茄子物种的野生近缘砧木可能是提高茄子产量的一种有价值的方法。
