영문 초록

The present study was focused on variability of qualitative characters in anther-dervied plants to obtain basic information for rice breeding through anther culture. Variability in the progeny of antherderived plants, A₂ lines, were compared with F₂ generation of the same cross combination. The frequency of tall in culm length was 79% in 594 F₂ plants, but 56% in 175 A₂ lines derived from Milyang 74/Dashukei 2 F₁ hybrids. The ratio of tall to short was 3:1 in F₂ population, and 1:1 in A₂ lines. Short culm of Milyang 74 was controlled by a recessive gene. There was no variants related to glaborous leaf blade of Dashukei 2 and resistant reaction to bacterial leaf blight, pathotype K₁, of Milyang 74 in A₂ lines. The glaborous leaf blade blade of Dashukei 2 controlled by a recessive gene and resistant reaction to bacterial leaf blight, pathotype K₁, of Milyang 74 controlled by a dominant gene were domonstrated in both F₂ population and A₂ lines derived from Milyang 74/Dashukei 2 F₁ hybrids.
