Abstract :Microspore cells develop into male gametophytes, which are released as pollen. Under certain stress conditions, the developmental pathway of microspores can be transformed into an embryo instead of pollen with haploid technology. In this experiment, 2 pepper breeding lines insert ignore into journalissuearticles values(G-1 and G-2); and 4 nutrient media formed with Murashige & Skoog insert ignore into journalissuearticles values(1962-MS); + 30 g L-1 sucrose or maltose and with or without vitamins as antioxidants. 0.05 mg L-1 biotin insert ignore into journalissuearticles values(vitamin B7); and 0.5 mg L-1 ascorbic acid insert ignore into journalissuearticles values(vitamin C); were studied as antioxidants. The anthers were pretreated for 2 days at 35 ºC in dark, then they were incubated in a climate chamber at 25 ºC and 16/8 hours photoperiodic conditions. The highest embryos rate, and development of embryos into the plantlet has been obtained from the medium containing maltose, and antioxidants. Although there was no significant differences between genotypes in medium- I insert ignore into journalissuearticles values(MS + sucrose);, medium-II insert ignore into journalissuearticles values(MS + sucrose and antioxidants); and medium-III insert ignore into journalissuearticles values(MS + maltose); in terms of embryogenic response, a significant difference was determined between genotypes in medium-IV insert ignore into journalissuearticles values(MS + maltose and antioxidants);. The number of embryos obtained from the G-1 in medium-IV has increased 2.5, 6.4, and 4.5 times, compared to the medium-I, medium-II, and medium-III respectively.
