영문 초록

Colored apiculus, awn, and long empty glume are indicators of wildness and are usually eliminated during rice domestication. Genetic analysis was conducted to clarify the inheritance patterns of awn, apiculus color, and long empty glume in Korean rice collection. Based on individual characterization of F₂ progenies derived from crosses between parents with colorless and purple apiculus, two (3 colored: 1 colorless) or three dominant genes (9 purple: 3 red: 4 colorless) are estimated as controlling this character by simultaneous complementary action. Different inheritance systems were detected between S237 and S245 of Shareibyeo which belong to the weedy type. To determine the genes responsible in awning and long empty glume characters, the inheritance of landrace varieties of rice ( Naengdo and Yuna ) was investigated. In the crosses of awned land race and awnless cultivar, three dominant genes are supposed to control the awning genetic system by 63 awned: 1 awnless individual. As for long empty glume, one recessive gene, g-l on the chromosome 4, was the one controlling the segregation ratio of 3 normal empty: 1 long empty glume. By analyzing the Korean rice collection, the inheritance systems of these wild characters may lead to a better understanding of rice domestication in the future.
