Research Notes: Resistance of soybean lines and cultivars to the root-knot nematode, Meloidogyne javanica

In a clayed soil heavy infested with Meloidogyne javanica at Guatapara farm , state of Sao Paulo , 36 soybean cultivars and breeding lines were tested for resistance to this nematode. Plots were constituted of three rows, 3 m long and 0.60 m apart and each plot was bordered on both sides with a row of \u27Davis \u27 cv, the susceptible check. Soybeans were seeded in November, 1979, in a randomized complete block design with eight replications
