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.
