AbstractThis study was conducted in local orchard, Abu-Ghraib district for 2006 season while the second season was carried out in local orchard-Falluja district 60 Km western Baghdad to study the effect of cross pollination on physical characteristics for Apple fruits CV. Anna, pollen grains were used from the cultivars (Aujami, Sharabi, Hajari, Magrabi and Fatimi). The average fruit weight was increased when open pollination carried out for the season 2006 to 119.92 gm and 146.59 gm when Anna cultivar pollinated with Sharabi cultivar in 2007 season, while the average fruit weight was decreased to 100.76 gm when self pollination was carried out during 2006 season.The average fruit size was significantly increased when open pollination used in 2006 season upto 185.00 cm3and to 181.66 cm3 when hand pollination between Anna and Magrabi cultivars during 2007 season, while the fruit size decreased when self pollination used to 133.33 cm3 during the first season and 155.00 cm3 when Anna cultivar pollinated with Aujami cultivar during second season.The highest average fruit length(7.36cm) was recorded when the open pollination was carried out during 2006 season. the crossing between Anna and Hajari cultivars gave the highest average fruit length during 2007 season upto 7.26 cm,while the lowest average fruit length of 6.73 cm was recorded when open pollination carried out during second season.Hand pollination of Anna cultivar with Sharabi cultivar resulted in the highest fruit diameter of 6.40 cm and 6.70 cm for both seasons respectively, while self pollination reduced fruit diameter to 5.96 cm during 2006 season.The highest average number of seeds 7.00 seed was found due to hand pollination between Anna and Fatimi cultivars during 2006 season, while the lowest of seeds per fruit 2.33 seed due to the self pollination for the same season. The crossing between Anna and Aujami cultivars gave 7.73 seeds per fruit in 2007 season, while the open pollination gave 3.33 seeds per fruit per fruit during the same season.
