Midwest crop production is dominated by two summer annual crops grown in rotation, viz., corn (<italic>Zea mays</italic> L.) and soybean (<italic>Glycine max</italic> L.). Winter oilseed crops, such as pennycress (<italic>Thlaspi arvense</italic> L.), can provide ecosystem and economic benefits when added to the corn–soybean rotation.

The objectives of this study were to (i) evaluate population development of three soybean cyst nematode (SCN; <italic>Heterodera glycines</italic>) biotypes on three pennycress genotypes and susceptible soybean and (ii) determine whether SCN inoculation level influenced plant biomass. SCN population density and biomass were determined after 60 d in the greenhouse. At the inoculation level of 2,000 eggs/100 cm3 soil, the average egg density for the three pennycress genotypes was 1,959 eggs/100 cm3 soil, lower than that for the susceptible soybean ‘Sturdy’ (9,601 eggs/100 cm3 soil). At the inoculation level of 20,000 eggs/100 cm3 soil, the average egg density for the three pennycress genotypes was 6,668 eggs/100 cm3 soil, lower than that for ‘Sturdy’ (40,740 eggs/100 cm3 soil). The inoculation level did not affect plant biomass. Pennycress is an alternative host to SCN under greenhouse conditions but is a less suitable host than soybean.

Midwest crop production is dominated by two summer annual crops grown in rotation, viz., corn (Zea mays L.) and soybean (Glycine max L.).

However, adding a new crop adds risks, such as increased pest pressure.
