Soybean varieties viable in southern Indiana, resistant to root-knot nematode

Root-knot nematodes, recently confirmed in southern Indiana, can cause extensive damage to soybeans, corn and watermelon, three of the main cash crops in that area of the Midwest. Purdue plant pathologist Andreas Westphal and his research team have identified several commercial varieties of soybeans that grow well in the area and are resistant or tolerant to this type of nematode and also to soybean cyst nematode.
