Inheritance of semi-dwarf and GA response in barley Ⅰ. Genetic analysis of semi-dwarf characters

This investigation was carried out to identify dwarfing sources of five Korean barley cultivars, Baekdong, Namhae, Songhak, Paldal, and Dusan 8. Three foreign cultivars, Himalaya, Svanhals, and Baitori 10 were used as the genetic markers of the dwarf genes, br, br₂ and uz respectively. Eight cultivars were crossed by all possible combinations so as to know the genetic sources of their culm lengths. The major dwarf gene of Baekdong was the uz by which Baitori 10 was controlled. Songhak was controlled by two independent recessive dwarf genes and one of them was considered to be uz gene. The crosses between Korean cultivars, Namhae, Paldal and Dusan 8, and the cultivars of three genetic markers showed that three Korean cultivars were controlled by one recessive dwarf gene different from br,br₂ and uz gene. In the crosses among three Korean cultivars, Namhae, Paldal, Dusan 8, each one was controlled by different gene or genes from another ones.
