In: Journal of Biological Chemistry and Environmental Sciences 2009.v.4(1)ISummary: The "Maekawa Jiro" (non-astringent persimmon cultivar) grown in Gropi farm, at Giza governorate was evaluated during 2004 and 2005 seasons. Results revealed that it gave high yield ranged from 12 to 16 tonslFeddan. Blooming was at March and flowering period ranged between two to three weeks. Fruit· set was about 30%, its maturity was at September. The fruit is medium to large (about 150 g.), oblate and four sided, and its skin is orange to yellow. The flesh is non-astringent type (at picking data, tannins were 0.327-0.33% but after two weeks declined to 0.191-0.203%. Random amplified polymorphic DNA (RAPD) analysis was carried out to evaluate polymorphism and genetic similarity between two persimmon cultivars, "Maekawa Jiro", a non-astringent type and "Costata", astringent type (The common cv. Planted in Egypt). Four random 10-mer primers were screened for RAPD markers. Three primers were used to assay genomic DNA from each cultivar. Each primer gave from 1 to 13 amplified bands with an average of 12.3 bands per primer. "Maekawa Jira" cultivar has the highest number of bands, and this polymorphism makes that numbers useful for genetic studies for persimmon cu1tivars. So, we can recommend to distribute Meakawa Jiro cv. As high yield cultivar with a pollination and nonastringent fruits.
