(1) evaluate this unique germplasm for resistance to two major pests, soybean cyst nematode and southern root-knot nematode, and identify agronomically superior genotypes for potential cultivar releases;
(2) incorporate the glyphosate resistance trait into nematode-resistant, high-yielding, long-juvenile lines;
(3) determine economic advantages or disadvantages of LJ genotypes when planted very early or late as compared to a conventional, full-season soybean crop and double-cropped soybean.
