Achieving self-compatible apricots by controlled crosses among selected cultivars

The native cultivated apricots in Iran are Asian grouped apricots and thus all are considered as self-incompatible.
For economic yield adequate pollination is necessary.
Planting self-compatible cultivars makes it possible to establish solid blocks of apricots and increasing uniform fruit production.
Controlled hybridization with selected parents was carried out to have self-compatible hybrids.
In this way, two commercial endemic cultivars namely: ‘Shams’ and ‘Shahroodi’ were crossed as seed plants with four self-compatible pollen donors; to obtain offspring with inherited “Sc” allele.
Common techniques were applied to test the auto-fertility of these 4-year-old hybrid trees.
The successful transmission of the “Sc” allele in this article is presented.
Some hybrid plants produce high-quality fruits.
The fruits are also characterized in this paper.
This work shows the ease of “Sc” allele inheritance in apricots.
