“…Iran is one of the most important producers of quince in the world. The growing of a single-cultivar in the quince orchard is common, but there are some economic concerns in a single-cultivar orchard, such as pollination and fruit set problems, as well as decreasing quality and yield (Tatari et al 2018).…”

Some morphological and physiological traits of seedlings in eight quince populations from seeds obtained in 2015 (350 progenies per population) were evaluated in 2017 and 2018. They resulted from open pollination of ‘Viduja’, KVD2 and KVD4 genotypes as well as from the crossings of ‘Viduja’ × KVD4, KVD2 × ‘Viduja’, KVD2 × KVD4, KVD4 × ‘Viduja’ and KVD4 × KVD2. Populations showed significant differences in some measured traits, including height and diameter of seedlings, canopy width, annual growth, leaf iron, and chlorophyll content, as well as catalase and peroxidase activities. Based on the results of descriptive statistics, a high variation coefficient was observed in canopy width, peroxidase activity, chlorophyll, and iron content traits. Results of simple correlation showed that there were significant positive correlations between leaf iron content and catalase activity as well as canopy width with both annual growth and leaf length. Cluster analysis among populations based on total traits divided the populations into four distinct groups. The role of the female parents was visible in reciprocal crosses of ‘Viduja’ × KVD4 and KVD2 × KVD4, but all populations with similar female parents were not grouped in the same clusters.

“…In single-cultivar quince orchards dominates selfpollination, resulting in flower and fruitlet abscission, which leads to the severe decline of yields (Tatari et al 2018). The cultivation of several cultivars in the quince orchards can prevent abscission and increase yield.…”

“…Quince orchards, however, confront significant challenges, notably the premature loss of flowers and fruits during early growth stages. This issue is multifaceted, influenced by factors such as water availability, soil quality, pruning practices, nutritional factors, and varying environmental conditions affecting pre- and post-pollination [ 6 , 7 ]. The interplay between pollination and compatibility is crucial in determining fruit production.…”

“…The interplay between pollination and compatibility is crucial in determining fruit production. A notable gap in pollination and an incomplete understanding of the mechanisms behind self-compatibility and self-incompatibility have been identified as primary contributors to the suboptimal fruit set in quince [ 7 ]. Despite reports of self-compatibility, a prevalence of self-incompatibility in a majority of quince cultivars and genotypes has been observed, suggesting a need for its consideration in breeding programs aimed at developing cultivars with enhanced fruit set and yield [ 7 ].…”

The Quince (Cydonia oblonga Mill.), typically known for its self-compatibility, surprisingly presents a degree of self-incompatibility. This research focused on exploring the diversity within the self-incompatibility gene locus (S) in various C. oblonga genotypes. Through meticulous DNA sequencing, the study sought to unearth potential novel S alleles. In the process of genotyping the S gene across multiple quince genotypes, not only were the previously documented S1 and S2 alleles identified, but this investigation also uncovered two previously unrecognized alleles, termed S4 and S5. These alleles, particularly S4, emerged as the most prevalent among the tested genotypes. To corroborate the findings derived from DNA sequencing, the study employed pollen tube growth germination assays. These assays elucidated a higher pollen germination rate in the Ardabil2 genotype in contrast to Behta. Additionally, the study involved assessing pollen tube growth in both Ardabil2 and Behta through cross-pollination techniques, meticulously tracking the development of pollen tubes at various stages. Remarkably, the outcomes demonstrated that the Behta genotype possesses self-incompatibility, whereas the Ardabil2 genotype showcases a notable degree of self-compatibility. This groundbreaking discovery of new S alleles in quince not only affirms the species’ self-compatibility but also sheds light on the complexities of allelic diversity and its impact on self-incompatibility. Such insights are invaluable for enhancing the yield of quince orchards through strategic breeding programs.
