        Soybean cultivars with genetically low levels of stachyose enhance the utilization of soybean in food as well as feed uses. The objective of this research is to obtain the information on indirection selection of soybean lines with low stachyose content using DNA marker based on RS2 (rs2) gene. Two genetic populations were developed from the crosses of three parents (116-13 parent : low stachyose content, PI417227 and PI506903 parents: normal stachyose content). Twenty F2 plants of RS2_ genotype and twenty F2 plants of rs2rs2 genotype from each populations were harvested. Content of stachyose was detected by HPLC. Stachyose contents (g/kg) of 116-13, PI417227, PI506903 parents were 3.7, 23.7, and 17.8, respectively. In population 1, stachyose content 20 F2 plants with RS2_ genotype was 14.8 – 24.1 and stachyose content 20 F2 plants with rs2rs2 genotype was 2.1 – 4.7. In population 2, stachyose content 20 F2 plants with RS2_ genotype was 12.4 – 19.7 and stachyose content 20 F2 plants with rs2rs2 genotype was 2.1 – 5.0. Mean difference between RS2_ genotype and rs2rs2 genotype in population 1 and 2 was highly significant. From this results, selection of genetic lines with low stachyose content by DNA marker based on RS2 (rs2) gene will be possible.

        Soybean [Glycine max (L.) Merr.] seed is an important dietary source of protein, oil, carbohydrates, isoflavones, and other nutrients for humans and animals. Raffinose and stachyose are the main antinutritional factors in soybean seed. They are carbohydrates belonging to the raffinose family of oligosaccharides, which are not readily digested in humans and cause flatulence or diarrhea. The genetic reduction of the raffinose and stachyose contents in mature soybean seeds will improve the nutritional value of soybean. The objective of this research was to evaluate agronomic traits with 10 F6 strains selected from breeding populations derived from a cross among seven parents. The contents of raffinose and stachyose in mature seeds were detected by high-performance liquid chromatography. Agronomic traits such as flower color, flowering date, harvesting date, lodging, plant height, seed coat color, hilum color, 100 seed weight, and yield were evaluated. Ten intermediate parents showed low raffinose and stachyose contents. The intermediate parent 883-1 had a small seed size, six intermediate parents (15A1, 15D1, RS-5, RS-33, RS-64, and RS-70) had a medium seed size, and two intermediate parents (14G20 and RS-21) had a large seed size. The intermediate parent RS-21 had a black seed coat and a green cotyledon. Four intermediate parents (883-1, 14G20, RS-5, and RS-21) had elite agronomic traits. The new intermediate parents developed through this study will be used to develop improved soybean cultivars with low contents of raffinose and stachyose.

        Soybean (Glycine max (L.) Merr.) is an important crop for protein, oil, carbohydrates, isoflavones, and many other nutrients to humans and animals. But, antinutritional factors in the raw mature soybean are exist. Raffinose and stachyose are main antinutritional factors in soybean seed. Both raffinose and stachyose are carbohydrates, belonging to the raffinose family of oligosaccharides (RFOs). RFOs are not readily digested in humans and cause flatulence or diarrhea. The objective of this research is to obtain the information on raffinose and stachyose content according to genotype and environment. A total of twenty two soybean genotypes (11 cultivars, 3 germplasms and 8 breeding lines) were selected. Each genotype was grown in the field for two years with two replications and harvested in bulk at natural maturity for two years. Content of raffinose and stachyose was detected by HPLC. The raffinose content (g/kg) of 22 genotypes was 2.68±0.21 - 5.87±2.43 in year 1 and was 3.24±0.37 - 9.05±0.16 in year 2. The stachyose content (g/kg) was 4.23±0.98 - 27.68±9.90 at year 1 and was 5.11±1.09 - 25.32±0.35 in year 2. Genotype and environment have highly significant effects on raffinose and stachyose content. Three genotypes (Da-7, 116-13, and RS-78) have low stachyose content at 5% significant level in two years. A positive correlation (R2=0.1985*) between raffinose and stachyose was observed in year 2. These informations are valuable in soybean genetics and breeding program related with raffinose and stachyose content.

        Soybean proteins are widely used for human and animal feeds worldwide. The use of soybean protein has been expanded in the food industry due to their excellent nutritional benefits. But, antinutritional and allergenic factors are present in the raw mature soybean. P34 protein, referred as Gly m Bd 30K, has been identified as a predominant immunodominant allergen. The objective of this research is to identify the genetic mode of P34 protein for the improvement of soybean cultivar with a very low level of P34 protein. Two F2 populations were developed from the cross of "Pungsannamulkong" x PI567476 and "Gaechuck2ho" x PI567476 (very low level of P34 protein). Relative amount of P34 protein was observed by Western blot analysis. The observed data for the progeny of "Pungsannamulkong" and PI567476 were 133 seeds with normal content of P34 protein and 35 seeds with very low level of P34 protein (X2=1.157, P=0.20-0.30). For the progeny of "Gaechuck#1" and PI567476, the observed data were 177 seeds with normal content of P34 protein and 73 seeds with very low level of P34 protein (X2=2.353, P=0.10-0.20). From pooled data, observed data were 310 seeds with normal content of P34 protein and 108 seeds with very low level of P34 protein (X2=0.156, P=0.50-0.70). The segregation ratio (3:1) and the Chi-square value obtained from the two populations suggested that P34 protein in mature soybean seed is controlled by a single major gene. Single gene inheritance of P34 protein was confirmed in 32 F2 derived lines in F3 seeds, which were germinated from the low level of P34 protein obtained from the cross of "Pungsannamulkong" and PI567476. These results may provide valuable information to breed for new soybean line with low level of P34 protein and identification of molecular markers linked to P34 locus.

        Dwarfuess 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 SDS-PAGE. 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 TiDf2: 44 Tidf2df2: 27 titiDf2: 11 titidf2df2) between df2 gene and ti gene was observed (x2 =3.53, P = 0.223). These results showed that df2 gene was inherited independently with the ti gene in soybean.
