ResumoThe role of the pollen parent on pollen tube growth, fruit set, fruit weight and seediness of cultivar 'Ellendale' tangor was investigated in two different commercial citrus-growing regions. Cross-pollinations were carried out with pollen of cultivars of 'Imperial' mandarin, 'Silverhill' satsuma, 'Emperor' mandarin, 'Dancy' mandarin, 'Murcott' mandarin and 'Valencia' orange. 'Ellendale' tangor was self-compatible, but showed a low fruit set with reduced seed numbers when self-pollinated. Cross-pollinations resulted in a higher fruit set with all except 'Silverhill' satsuma pollen which showed high pollen sterility. Fruit weight and seediness of 'Ellendale', showed significant differences among pollen parents. 'Murcott' and 'Emperor' pollen gave the largest fruits with high levels of seeds. 'Imperial' pollen resulted in low seed numbers without significantly affecting fruit size. Fruit quality of 'Ellendale', in terms of low seed numbers, may be maintained when it is planted in solid blocks or with 'Imperial' mandarin. However, 'Murcott' and 'Emperor' pollen increased seediness appreciably.
