Mapping soybean locus, which confers resistance to soybean cyst nematode race 1 in combination with and derived from PI 84751.

The soybean cyst nematode (SCN) ( Ichinohe) is a devastating pest of soybean ( (L.) Merr.) in the world.

Mapping versatile QTL for soybean downy mildew resistance.

Three versatile QTL for soybean downy mildew resistance in Japan were detected using five RIL populations and confirmed using recombinant fixed pairs or a backcrossed line. Downy mildew reduces soybean seed quality and size. It is a problem in Japan, where 90% of soybean grown is used as food.
