Evaluation of embryological potential of soybean cultivars zoned in forest, steppe, and marshy woodlands of Ukraine as essential stage for the further transformation

Seven soybean (Glycine max (L.) Merr.) cultivars zoned in forest-steppe and marshy woodlands of Ukraine: "Chernuatka", "Vasylkivska", "Kyivska-91", "Kyivska-27", "Marjana", "Chernobura" and "Altair" were established in vitro for somatic embryogenesis inducing. Cultivars "Marjana" (88%) and "Vasylkivska" (86%) demonstrated the highest embryogenic capacity among all the tested cultivars. During the further plant regeneration cultivars "Marjana" and "Kyivska-91" showed the best capacity to form adult plants despite the fact that embryogenic capability of the cultivar "Kyivska-91" was 71%. According to the obtained data three genotypes were selected for the further investigation of effective methods of biolictic transformation of ukrainian cultivars.
