In interspecific and intraspecific crosses, and pre-zygotic barriers like pollen-pistil incompatibility may exist. And when a parent is selected as male or female, this incompatibility may disappear. In this experiment, seven high-yielding commercial cultivars of potato, two advanced potato clones of direct intraspecific hybrids (Solanum tuberosum ssp andigena x S. tuberosum) and three advanced clones of S. tuberosum hybrids were crossed reciprocally, in the Ardabil Natural Resources and Agricultural Research Station during the summer of 2013 and the best cultivars and clones were determined when they were selected as the female or male parent. Generally, when the commercial cultivars were used as the male parent, the number of berries, the total number of seeds, the number of the seeds per berry, cross efficiency and the germination percentage of true seeds generated were 5, 73, 15, 0.73 and 27%, respectively; and when the parent was female, the above were measured as 74, 3841, 59, 3.
