Comparative Study of The Physico-Chemical Properties between Some Pollinizers for Bartamoda Dates in Aswan Governorate

This study was carried out during the 2020 and 2021 seasons to select and evaluate some male date palm trees for pollinating Bartamoda cultivar in Aswan governorate, Egypt. For this purpose, twenty-three different Maghal date palm male types, which are grown in Aswan governorate, were chosen to evaluate and recommend the best to be used as a pollinizer for Bartamoda date palm cultivar. Pollen grains from each male type were used as a pollinizer to test the impact of each male type on fruit set and fruit quality. Data showed that Male 22 had higher values for the initial fruit set percentage, retained fruit percentage, fruit weight, flesh weight, fruit length, fruit diameter, total soluble solids, total sugars, reducing sugars and non reducing sugars, and lower values for seed weight, seed length, seed diameter, and pH value of Bartamoda date palm fruits compared to the other males grown in the rest of the locations under study in Aswan governorate.
