|Abstract: ||The effect of open, self and cross pollination within and between three cultivars of pomegranate, namely: Khob El-Jamil, Taiefe and Al-madina on fruit set, seed number, fruit quality and yield were studied for two consecutive years. Percent of male and perfect flowers varied considerably according to the cultivar. The proportions of male to perfect flowers were 0.12, 0.35 and 0.37 for Khob El-Jamil, Taiefe and Al-madina cvs., respectively. Lowest pollen viability percentage was in Al-madina and the highest pollen viability was in Khob El-Jamil cultivar. Hand self pollination (HSP) in Khob El-Jamil cultivar increased fruit set percentage, followed by hand cross pollination with pollen grains from Taiefe or Al-madina cultivars (HCPT and HCPM). Results of fruit set percentages and seed number per fruit revealed that a partial self incompatibility was existing in Al-madina cultivar. A certain degree of cross incompatibility was found when Al-madina as seed parent was pollinated with Taiefe cultivar. Hand self pollination in Khob El-Jamil and Taiefe cvs. gave higher yield compared to other pollinizers. Application of pollen from Khob El-Jamil to emasculated flowers of Al-Madina cultivar significantly affected the weight, volume and size of fruits when compared with pollen of aiefe cultivar. Also, open pollination (OP) treatment in Khob El-Jamil cultivar significantly decreased peel thickness and juice volume compared to hand self pollination. Cross pollination in Taiefe cv. with pollen from Khob El-Jamil increased TSS, acidity and anthocyanin content of peel and pulp.|
