水稻品種 “統一”과 “統一찰”의 遺傳背景 Ⅰ. Polyacrylamide gel 等電點電氣泳動에 의한 種子 esterase isozyme의 band 類型

Genetic background of rice variety “Tongil” and “Tongilchal” Ⅰ. Esterase isozyme banding patterns in rice grain by polyacrylamide gel isoelectric focusing

Polyacrylamide gel isoelectric focusing was used to analyze the grain esterase isozymes of rice varieties, Tongil, Tongilchal and their related parents. Six major bands were revealed in the gel part of high pH and observed different banding patterns. Esterase isozyme banding patterns in grains were separated into three types, namely Est-Ⅰ, Est-Ⅱ and Est-Ⅲ in this experiment. Of the varieties analyzed, Japonica showed Est-Ⅰ and Indica was both Est-Ⅰ and Est-Ⅱ, while Japonica×Indica showed Est-Ⅲ, respectively. Esterase isozyme banding patterns of Tongil, Tongilchal, IR8, IR262, IR833, IR1317 and Peta were identical. It was concluded that the source of esterase isozymes genotype in grains of Tongil and Tongilchal was Indica variety Peta.
