Telah dilakukan analisis kadar protein dan vitamin C dalam kedelai hitam (Glycine soja (L.) Merrill) dan kedelai kuning (Glycine max (L.) juga tahu dengan beberapa pengerjaan yang berbeda dengan rata-rata perbedaan kadar yang didapat selisih 1% lebih besar kadar kedelai hitam (Glycine soja (L.) Merrill) dibanding kedelai kuning (Glycine max (L.) Merrill) untuk persentasi kadar protein. Sedang untuk kadar vitamin C selisihnyaa tidak mencapai angka 1% namun tetap saja kadar tertinggi dimiliki oleh kedelai hitam (Glycine soja (L.) Merrill) maupun produk olahan tahunya. Pada Uji hedonik yang dilakukan terhadap tahu goreng kedelai hitam (Glycine soja (L.) Merrill) dan tahu goreng kedelai kuning (Glycine max (L.) didapatkan persentasi kesukaan para panelis sebesar 80,66% dan 6733%. Kata Kunci : Kedelai, Tahu Kedelai Kuning, Tahu Kedelai Hitam, Protein, Vitamin C. ABSTRACT We analyzed the levels of protein and vitamin C in the black soybean (Glycine soja (L.) Merrill) and yellow soybean (Glycine max (L.) is also out with a few different treatments with an average difference of differences in levels gained 1% larger levels of black soybean (Glycine soja (L.) Merrill) than yellow soybeans (Glycine max (L.) Merrill) to the percentage of protein content. Moderate to high levels of vitamin C difference not reach the 1% but still owned by the highest levels of black soybean (Glycine soja (L.) Merrill) and processed him. Hedonic In the test conducted on the fried tofu black soybean (Glycine soja (L.) Merrill) and fried tofu yellow soybean (Glycine max (L.) A percentage obtained by the panelists 80.66% and 6733%.

The effect of selection for high seed protein content on plant development in soybeans (Glycine max (L.) Merr.) was investigated by comparing the lengths of growth stages of four selected populations with those of a nonselected control. Each population, grown at two locations in one season, was a composite of four crosses between G. max and its putative wild ancestor, Glycine soja Sieb. and Zucc. The growth stages were planting to emergence, emergence to flowering and flowering to maturity. The length of each growth stage was measured in soybean development units (SDU) and in days. On average, populations selected for protein alone required more SDUs from planting to emergence and from emergence to flowering and fewer SDUs from flowering to maturity than did the control. The mean temperature in the stage from flowering to maturity was negatively correlated with protein content in all populations. The correlations ranged from −0.22* to −0.34**.

Twelve isoflavones and eight anthocyanins were quantified in black soybean seeds by HPLC-MS analyses; the coupled OPLS-DA multivariate statistical analysis helped us to determine their geographical origin.
