“…Nevertheless the difficulties by anther culture were obtained pepper lines possessed traits such as high productivity, disease resistance, fruit quality ets. (HWANG et al, 1998;ARNEDO ANDRES et al, 2004;SHRESTHA et al, 2010). The genetic homogeneity of anther-derived lines can be determined on the basis of analysis of plant and fruit traits in successive generations (SUPENA et al, 2006;KISIAŁA et al, 2011).…”

The comparative breeding evaluation was carried out with six advanced pepper lines (Capsicum annuum L.) with androgenic origin and their initial pepper variety Hebar during the period 2008 - 2010 in field conditions at Plovdiv, Bulgaria. The genotypes were characterized by total and standard yield, plant height and fruit traits: length, width, wall thickness and weight. The response of two lines (4 and 6) and control variety to the Verticillium wilt was also investigated on artificial infected background. According to the results of the experimental work standard and total yield in all androgenic lines were higher compared to the initial variety but significant differences were established only for lines 1, 2, 4 and 6. Line 6 was characterized with the highest standard yield (4009 kg/da) followed by line 2 (3829 kg/da). They exceeded variety Hebar with 42.26% and 35.89%, respectively. Line 2 formed the heaviest (61.31 g) and longer (11.24 cm) fruits than most studied genotypes. Anther-derived lines were also with a good uniformity by studied traits. In line 6 was registered lower index of infestation byVerticillium dahliae Kleb. than the control during the investigated period. These perspective lines will be included as valuable genetic resources for future pepper breeding programs for development of new varieties

“…in this manner by doubling chromosomes in haploid plants it is possible to obtain genetically stable homozygous lines in a short time thereby providing a method for speeding up and increasing the selection efficiency. Such homozygous DH plants have been used in breeding programmes for production of pure lines and new highly adaptive and productive varieties (1,4,8,15,16,18,20,21,23,24,35,41,48). A number of studies (2,19,37,45,53,55) also reported that the obtained by the in vitro anther culture techniques haploids and Dh plants are an appropriate system for genetic manipulations, gene mapping and mutant line selection.…”

“…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.
