Identification of the promising mango rootstocks and their response to grafting of some foreign mango cultivars in the nursery [electronic resource]

Includes bibliographic reference

This study was conducted during two successive seasons 2021 and 2022 to evaluate the performance of some scion of foreign imported mango cultivars (Keitt, Naomi, Osten and Shelly) on three rootstocks (Sukkary, Zebda and 4/9) grown in sandy soil with drip irrigation system in a private orchard nursery at Almansoria, Giza Governorate, Egypt. This experiment was laid out in a split-plot design to study the success, initial growth performance and vegetative characteristics. Results clearly showed that, grafting of studied different mango cultivars on Sukkary, Zebda and 4/9 rootstocks had a significant influence on studied growth parameters. Where the highest number of leaves/scion was found in Keitt and Naomi cultivars grafted on 4/9 rootstock. Moreover, number of growth cycles /scion was the highest in Naomi cultivar grafted on 4/9 rootstock. Grafting Osten, Keitt and Naomi cultivars on 4/9 rootstock enhanced stem height above of grafting area. The highest leaf surface area was found with Osten cultivar grafted on 4/9 rootstock. The obtained results clear that 4/9 rootstock present a promising performance under Egypt conditions.
Key words: Mangifera indica L., cultivars, grafting, rootstocks, scions.
