Forty-three open-pollinated maize varieties were tested for resistance to the southern root-knot nematode, Meloidogyne incognita race 4, in greenhouse tests. An experiment repeated on five different planting dates assessed nematode reproduction 60 days after inoculation with 3,000 eggs per plant. Tebeau and Old Raccoon showed consistently high levels of resistance in all plantings, with the lowest reproduction factor (RF) values (0.2 and 0.4) and low numbers of eggs per gram of fresh root (222 and 955). Bill Dailey Variety and Sheppard Corn had the same level of resistance to M. incognita as the resistant hybrid, Mp307 x Mp707, but they were less consistent in different plantings. Levi Mallard, African Bushman, and Field's White Variety were the most susceptible varieties with RF values of 3.1-3.3 and 2,479-3,678 eggs per gram of fresh root.
在温室试验中，对43个开放授粉的玉米品种进行了抗南方根结线虫（Meloidogyne incognita 4号小种）的测试。在五个不同的种植日期重复进行了一项实验，评估每株接种3000个卵60天后线虫的繁殖情况。Tebeau和Old Raccoon在所有种植中均表现出持续的高抗性，繁殖系数（RF）值最低（分别为0.2和0.4），每克鲜根中的卵数也较少（分别为222和955）。Bill Dailey Variety和Sheppard Corn对南方根结线虫的抗性水平与抗性杂交种Mp307×Mp707相同，但在不同种植中表现不太一致。Levi Mallard、African Bushman和Field's White Variety是最易感品种，RF值为3.1 - 3.3，每克鲜根有2479 - 3678个卵。
