In interspecific and intraspecific crosses, pre-zygotic barriers like pollen-pistil incompatibility may exist, and in the case that a parent is selected as male or female, this incompatibility may disappear. In this investigation seven high yielding commercial cultivars of potato (Agria, Savalan, Picasso, Caesar, Daifla, Luca and Satina) were reciprocally crossed with eleven promising potato clones in Ardebil Agricultural and Natural Resources Research Station during the summer of 2014 to obtain cheep TPS hybrids. The best cultivars and clones were appointed when they were as male and female. Results of two pollen fertility tests showed that cultivars Agria and Luca and clones AS10 and AS72 were sterile and did not produce fruit when participated as mate parents in crosses. Generally, when commercial cultivars were as female, the number of fruit and seed, seed weight, cross efficiency, strength and uniformity of germination and seedling growth were better.When commercial cultivars were considered as female parent and clones as male parent, Savalan, Caesar and Luca cultivars showed better traits than other cultivars. When clones were mate and commercial cultivars female, HS Clone and UT42 had higher percentages of fruit and seed set, crossing efficiency, percentage of seed germination and 100-seed weight. In crossing, when the commercial cultivars were male and clones were female parents, clones AS72 and AS10 had better traits than the other Clones. |
