Research Abstract |
Soybean seeds contain low levels of α-tocopherol (Toc). Since α-Toc acts as vitamin E efficiently, increasing α-Toc content will improve nutritional value of soybean. Lutein shown to reduce risks for ocular diseases is found in low in the seeds. We have identified varieties with high α-Toc and wild soybean strains with high levels of lutein content. Genetic analysis of the high α-Toc and lutein traits, respectively, revealed that the high α-Toc and lutein contents are highly heritable. Two SSR markers, Sat_243 and Sat_167 were shown to be associated with high α-Toc content. We obtained some lines with high levels of lutein and α-Toc contents in the progenies. Accumulation of high contents of α-Toc and lutein was possible.
