영문 초록

This investigation was carried out to reveal the relationship between dwarfing sources and gibberellic acid responses with semidwarf barley cultivars, Baekdong, Namhae, Paldal, Dusn 8 and dwarf marker cultivars, Himalaya (br), Svanhals(br₂), Baitori 10 (uz). For analyzing growth response of first leaf internode length and its inheritance to GA₃ treatment, all possible combination crosses of above cultivars were performed. The optimum GA₃ concentration for elongating responses of first leaf internode length was 10ppm in barley. Five cultivars, such as Baekdong, Namhae, Hymalaya, Svanhals, Baitori 10 were low growth response of first leaf internode elongation to GA₃ while others were intermediate. Dominant alleles to dwarf genes, such as br⁺, br⁺₂, uz⁺ expressed complementary epistasis in the growth responses of first leaf internode length to GA₃ and it was revealed that Baekdong has the uz gene of Baitori 10 because of its same response. The growth response of first leaf internode length in Namhae showed complementarity of 2 dominant genes as that of the marker cultivars and the genes which control the responses of first leaf internode length in Paldal and Dusan 8 were considered to be same pattern in controlling their responses.
