Gene Discovery Could Overcome Aluminum Barrier To Higher Wheat Yields Worldwide
...01) 504-8324] USDA scientists developed a soybean strain with both high yields and high protein levels. This is a first in soybean breeding and will overcome the problem of decreasing protein levels as seed yield increases. [Contact: Richard F.
