Abstract

The blooming period of Dorsett Golden cultivar was 35-38 days, which coincides with the blooming period of Anna (28-32 days). Ein­Shemer blooming period was comparably shorter (14-21 days). This per­iod did not completely coincide with the blooming period of "Anna". The highest fruit set was obtained under open pollination condi­tions. The best pollinizer for "Anna" cultivar was "Dorsett Golden" which gave the highest fruit set (65.00 and 66.66%) compared to Ein-Shemer pollinizer which gave the lowest (4.03 and 35.00%) in two seasons. The pollen viability of the three cultivars ranged from 73.30 to 86.10% in 15% sucrose.
