“…These findings are in alignment with previous findings that reported the effect of donor plants (Cheng et al 2013), microspore developmental stage (Parra-Vega et al 2013a), culture medium (Irikova et al 2011a;Nowaczyk et al 2016;Ata et al 2019;, growing conditions and age (Irikova et al 2011b;Parra-Vega et al 2013b;Popova et al 2016;. Niklas-Nowak et al (2012) observed that the significant differences were seen in the androgenic response of tested genotypes of individual plants and confirmed that the donor plant genotype is a critical factor in determining the effectiveness of androgenesis in pepper, which is in coherence with our findings.…”

“…Variation for fruit morphological and agronomical traits observed between genotypes of Stryama, Zlaten medal 7, and Victoria varieties background and similar observations have been observed in previous studies in regard to fruit morphological traits variation among androgenic lines of similar background (Shrestha et al 2011;Luitel et al 2012;Shmykova et al 2014;Trajkova and Koleva-Gudeva 2017). The breeding value of different pepper androgenic material has been observed by many authors and promising breeding lines have been created for enhanced fruit quality (Shrestha et al 2011;Luitel and Kang, 2013b;Nowaczyk et al 2014;, improved productivity, plant and fruit traits (Koleva-Gudeva and Trajkova 2012;Luitel et al 2012;Todorova et al 2013;Shmykova et al 2014;Trajkova and Koleva-Gudeva 2017;. Applications of pepper androgenesis have not only been limited to fruit quality and fruit morphological traits, but have also been useful in creating DH lines that have resistance against economically important viral, bacterial (Hwang et al 1998), and fungal diseases (Todorova et al 2013), and nematodes (Ö cal et al 2019;Shimira et al 2019).…”

The Balkan pepper breeding program aims to use in vitro embryogenesis (anther culture) to develop doubled haploid pepper lines with valuable traits. We analyzed the effectiveness of microspore embryogenesis on 17 pepper genotypes comprised of varieties, breeding lines, and F1 hybrids of different varietal types (conical, bell shape, and kapia) and characterized the agronomic traits of newly generated doubled haploid lines. The highest androgenic potential was observed in the variety Stryama and breeding line 560/06 with 9.55 and 13.00% reacted anthers, respectively. Of the 186 regenerated plants, 147 were successfully adapted with a survival index of 79.03%. Flow cytometry analysis showed that the haploid:diploid ratio of regenerants was 1.5:1. All diploid plants were confirmed to be androgenic in origin. There were significant differences in terms of quantitative fruit characteristics of length, width, weight, pericarp weight, pericarp thickness, and productivity per plant among the diploid lines. Also, androgenic lines 21, 23, and 74 derived from Stryama and line 55 obtained from Zlaten medal 7 were distinguished with higher values of some fruit traits compared to initial genotypes. Additionally, several androgenesis lines (Stryama lines 21, 23, and 74, and Zlaten medal 7 line 55) scored higher for some fruit traits compared to the initial genotype. These results show that anther culture is a promising tool for the creation of Balkan pepper breeding lines with improved traits.

“…Higher visual and taste quality, fruit firmness, dry matter content, total soluble content, titratable acidity, phenolic content, and antioxidant activity were exhibited in pepper DHs (Luitel and Kang, 2013b). Nowaczyk et al (2014) proved that DH technology can be successfully used for the rapid genetic stabilization of soft-flesh Capsicum spp. recombinants.…”

IntroductionIn general, haploid cells or individuals are those in which the original chromosome number has reduced by half. According to Seguí-Simarro (2010), androgenesis can be defined as a set of biological processes leading to an individual that genetically originated exclusively from a male nucleus. After spontaneous or induced genome doubling, double haploids (DHs) that are completely homozygous are obtained. The production of haploid plants can be induced by methods such as parthenogenesis, interspecific hybridization, pollination with irradiated pollen, hormonal and/or chemical treatment, and application of high-temperature stress (Forster et al., 2007;Murovec and Bohanec, 2013). In anther culture, haploids and DHs occur through direct microspore embryogenesis. This technique has no analogue for fast creation of pure homozygous lines in a single step. In pepper-plant breeding, for example, this method has helped in the development of important new varieties with improved adaptability, productivity, and disease and pest tolerance (Chunling and Baojun, 1995;Venczel and Mitykó, 1995;Arnedo Andrés et al., 2004;Nervo et al., 2007). DH lines are a suitable material for genetic and molecular studies, and this determines their high value in molecular breeding as well (Madhusudhana, 2015).Regarding the genus Capsicum, the first haploids were derived by in vitro anther culture of C. annuum and C.

Chipotle peppers were grown in America before being carried to Europe by Columbus. Capsicum breeding began with choosing wild species for desired characteristics, with additional development based on precision selection. To improve capsicum yields, traditional methods such as mass selection, pedigree, single-seed descent, backcrossing, and hybridization are being used. Capsicum has a high level of genetic diversity due to multiple new gene rearrangements. Capsicum fruits are high in nutrients that are beneficial to human health. As a result, the world market for and consumption of capsicum has lately grown. Capsicum breeding programmes aim to improve yield, biotic, abiotic resistance, and nutritional quality. Recent breakthroughs in capsicum breeding have included introgression, mutation breeding, polyploidy, haploidy, embryo rescue, and the use of genetic markers. Molecular technology has grown into an important tool that, when coupled with classic selection and hybridization procedures, has the potential to result in great success in an established capsicum genetic breeding programme.
