초록

Resistance to herbicide was the first trait to be introduced into crop plants using new
genetic approaches for a number of technical and practical reasons. The agronomic importance of herbicides
is a major driving force behind the development of herbicide resistant plants. Insertion of herbicide
resistant gene allows selective control of production of weeds in rice cropping systems. This study was
conducted to investigate the major characteristics of genetically modified elite rice, Iksan483, compared
to a non-transgenic rice varieties. The herbicide, glufosinate, resistant transgenic elite rice Iksan483
showed similar phenotypic traits compared to a non-transgenic rice variety Shindongjinbyeo and
Anjungbyeo. Heading date and culm length of Iksan483 were same with Shindongjinbyeo, but slightly
earlier and shorter in Anjungbyeo. In panicle length of Iksan483 was shorter than Shindongjinbyeo and
Anjungbyeo. In yield components and yield, Iksan483 was inferior except for percentage of ripened
grain and yield index showed 88% to Shindongjinbyeo. Grain apparent traits of Iksan483 showed
shorter grain type than Shindongjinbyeo and same with Anjungbyeo. There is no white core and belly
grain in Iksan483 as Anjungbyeo. In grain quality traits, contents of amylose and protein of Iksan483
was slightly high compared with Shindongjinbyeo, but Toyo meter showed low index. In the test of leaf
blast and bacterial leaf blast, leaf stripe virus resistance in Iksan483 showed similar resistance with Shindongbyeo
and Anjungbyeo.
