Abstract
This study was carried out to improve Banana crop growth and productivity byplanting cultivars that may be tolerant to banana diseases with high productivity and quality. Threeimported cultivars (Zeef, Grand Nine, and Canary) were planted in private orchard in El SalhyaDistrict, Sharkia Governorate, Egypt in two consecutive seasons of 2016 and 2017. The results of thiswork indicated that Zeef and Grand Nine were significantly higher in growth parameters such asplants length and number of functional leaves than Canary. Similar results were noticed inproductivity parameters where Zeef plants and Grand Nine were significantly higher than Canary suchas total yield, bunch weight, bunch length, finger length and diameter, while no clear differences werefound in quality components. Also the second season 2017 (the first sucker) was higher than the firstone (Mother) in the three cultivars in all parameters. Also Zeef plants and Grand Nine recorded thehighest value for each of antioxidants enzymes, soluble sugars and proline, this reflects that defensesystem in both cultivars was stronger than Canary cultivar, so they were more tolerant to diseases thanCanary plants. Therefore the general evaluation showed that Zeef and Grand Nine banana cultivars areconsidered promising cultivars for the Egyptian conditions with high productivity and quality andtolerant to biotic and abiotic stresses.
