“…Although self-incompatibility had been previously reported for some mango cultivars (Singh et al, 1962;Mukherjee et al, 1968;Sharma and Singh, 1970;Ram et al, 1976;Gehrke-Vélez et al, 2012;Dutta et al, 2013), our results with 'Osteen', 'Kent' and 'Kensington' do not suggest an evident self incompatibility system at the stigma or style level that can significantly affect pollen tube growth.

“…Floral incompatibility systems are a common phenomenon in several plant species, resulting in the avoidance of self-fertilization or crossing with genetically close genotypes favouring genetic exchange. The occurrence of self-incompatibility in some mango cultivars has been described previously (Singh et al, 1962;Mukherjee et al, 1968;Sharma and Singh, 1970;Ram et al, 1976;Gehrke-Vélez et al, 2012;Dutta et al, 2013), but no conclusive data about a possible incompatibility system in this species have been put forward. In this study a combination of molecular and microscopic techniques was used.…”

Mango (Mangifera indica L.) is a tropical fruit tree originated from Southeastern Asia, which is cultivated worldwide in regions with tropical and subtropical climates. Mango cultivation area has significantly extended in the last decades often to regions where environmental conditions are not the most favourable for optimal mango flower development and fruit set and, consequently, several reproductive problems had been described in this species. Some of them could be related to self-incompatibility, but so far information is not clear on the possible self-incompatibility system operating in this crop. In this work we study pollen tube growth, following self and cross pollination, in three mango cultivars ('Osteen', 'Kent' and 'Kensington'). Paternity was also determined in the offspring of two of these cultivars-'Osteen' and 'Kent'-and in a solid block of an additional cultivar, 'Keitt'. Sequential examination of pollen tube

Abstract. Hidayat A, Rahayu ES, Abdullah M, Retnoningsih A. 2021. Microsatellites to reveal genetic diversity and to distinguish four mangoes of Tegal District, Central Java, Indonesia. Biodiversitas 22: 3467-3473. The Wirasangka mango is Tegal District’s flora of identity, which requires recognition, and its existence deserves to be preserved. However, based on the morphology of the fruit, most of the people of Tegal still have difficulty distinguishing the wirasangka mango from other mangoes. Molecular markers are needed to ascertain the differences between these mango varieties. Microsatellite DNA is a repeating DNA of stable DNA markers with high repeatability and polymorphism. This study analyzes the level of genetic diversity and microsatellite alleles that can differentiate four mangoes from Tegal District, Central Java, Indonesia, i.e. wirasangka, tengkueh, golek, and okyong. Eleven accessions of six locations in Tegal District were analyzed using ten microsatellite loci. The microsatellite amplification result was separated using electrophoresis in 6% polyacrylamide gel and then visualized with silver dye. A total of 35 microsatellite alleles were found measuring 100-1000 bp, ranging from 1-7 alleles for each locus. The average polymorphism information content (PIC) of 0.54 indicates that genetic diversity is relatively high and informative. Therefore, the microsatellite alleles can be used to differentiate mango varieties. The specific allele characteristic of wirasangka mango accession is locus AJ63516, with an allele size of 600-700bp.

“…Mango fruit drop due to a putative incompatibility system has been proposed and supported by several authors (Singh et al, 1962;Mukherjee et al, 1968;Sharma and Singh, 1970;Ram et al, 1976;Gehrke-Vélez et al, 2012). To check if an incompatibility system is operating in the varieties studied in this work, a paternity analysis was performed using microsatellite markers in fruits harvested in a multivarietal and in a monovarietal orchard.…”

Mango (Mangifera indica) is a tropical fruit tree originated in Southeastern Asia, which is cultivated in regions with tropical and subtropical climates worldwide. Mango cultivation has significantly increased in the last decades, often spreading to areas where environmental conditions are not the most favorable for optimal fruit set. In this work, we describe the reproductive biology of mango in the coastal areas of Southern Spain, the furthest region from the equator where mango is produced commercially at a significant scale. As in other regions, mango trees produced several inflorescences per tree with hundreds to thousands of male and hermaphrodite flowers, depending on the cultivar, but only a very small percentage of the flowers are able to set fruits due to a massive drop of flowers and fruitlets. Although about half of the flowers in the inflorescence are male flowers and, consequently, contribute to this massive drop, a high proportion of the hermaphrodite flowers were not receptive to pollen germination. In receptive flowers, the characterization of the pollen tube pathway within the pistil showed chalazogamy. A detailed study of the ovules indicates that a high proportion of them showed degenerated embryo sacs, both before and after fertilization. Paternity analysis with molecular markers showed a high proportion of embryos resulting from self-pollination in orchards planted with a single cultivar. However, without pollination restrictions, the offspring shows a higher proportion of genotypes resulting from cross-pollination, suggesting preferential cross-fertilization. The variable response of this parameter, together to the variable proportion of hermaphrodite/male flower ratio, also obtained in response to environmental conditions, suggests a reproductive plasticity in this species.
