Inheritance of plant height was studied in Zhepi 1 and Aizao 3, two dwarfing gene donors used in barley (Hordeum vulgare L.) breeding programs in China. With direct cross and para-backcross methods, allelism tests were conducted for Zhepi 1 and Aizo 3 with barley entries carrying either brh 1, uzu 1, sdw 1, or six new dwarfing genes recently identified in Chinese barley accessions. Plant height in both Zhepi I and Aizao 3 was controlled by the same recessive dwarfing gene. The dwarfing gene carried by both of these cultivars is different from the three known and the six new dwarfing genes. Based on the results of this study, only two dwarfing genes have predominantly been used in barley breeding in China since 1950.
