As the soybean cyst nematode (SCN), Heterodera glycines Ichinohe, has become a serious pest of soybeans in the USA, development of resistant culti-vars has received greater attention. This necessitates screening of large numbers of plant progenies to locate SCN-resistant isolates in segregating generations. Ross and Brim (1957) used a double-row method to detect SCN-resistant strains of soybeans.
