Crop Science 46:865-869. HYPERLINK "http://crop.scijournals.org/cgi/reprint/46/2/865" http://crop.scijournals.org/cgi/reprint/46/2/865 Chen et al focus on one single trait identified in QTL analysis: plant height. In modern strands the soybean grows straight, like a stalk. Wild strands are like vines, almost like weeds and extremely hard to measure. In order to compare particular germplasm data and to evaluate cultivars this kind of data was needed. For this reason different methods were used to measure height and maturity levels. Different maturity markers (defined by points of height) were given to wild strands and the conclusion was that wild soybeans mature much more rapidly than domestic ones. Most importantly, wild soybean grows more rapidly and robustly earlier in its life than domestic soybean. Chung, Gyuhwa; Singh, Ram J. 2008. Broadening the Genetic Base of Soybean: A Multidisciplinary Approach. Critical Reviews in Plant Sciences, 27(5):295-341. HYPERLINK "http://www.informaworld.com.proxy.library.ucsb.edu:2048/smpp/section? content=a903079876&fulltext=713240928" http://www.informaworld.com.proxy.library.ucsb.edu:2048/smpp/section? content=a903079876&fulltext=713240928 Authors and researchers of this article employed a multidisciplinary approach to broaden the genetic base of the soybean through various modern biotechnological analyses. They build on knowledge already known about the wild progenitor of the modern Glycine max (Glycine soja), and comment on the difficulties currently in determined a smaller geographic origin. Since the 1970s, agreements about the geographic origin has become narrower, but still is very broad. It is currently thought that the soybean was domesticated in the 11 th Century under the Shang Dynasty in China, however some theories suggest that it was domesticated independently in different East Asian regions. Narrowing the genetic base and comparing molecular data will allow us in the future to narrow further the geographic location of the soybean since archaeological evidence is scarce and sometimes inconclusive since wild and domestic soybean seeds did not differ in size even during early soybean cultivation.
