영문 초록

Dwarfness and Kunitz trypsin inhibitor (KTI)protein in soybean is useful traits for basic studies. df2 and ti gene control dwarfness and the expression of Kunitz trypsin inhibitor (KTI) protein in soybean, respectively. The objective of this research was to verify genetic linkage or independent inheritance of df2 and ti loci in soybean. The F2 population was made by cross combination between “Gaechuck#2”(Df2Df2titi genotype, KTI protein absence and a normal growth type) and T210 (df2df2TiTi genotype, a dwarf growth type and KTI protein present). A total of 258 F2 seeds were analyzed for the segregation of KTI protein using SDSPAGE. And so, 198 F2 plants were recorded for the segregation of dwarfness. The segregation ratio of 3 : 1 for Ti locus (201 Ti_ : 57 titi) and Df2 locus (143 Df2_ : 55 df2df2) was observed. Segregation ratio of 9 : 3 : 3 : 1 (116 Ti_Df2_:44 Ti_df2df2: 27 titiDf2_: 11 titidf2df2) between df2 gene and ti gene was observed (χ2= 3.53, P = 0.223). These results showed that df2 gene was inherited independently with the ti gene in soybean.
