Ketahanan Beberapa Varietas Kedelai Terhadap Nematoda Puru Akar (Meloidogyne incognita)

Abstract

Resistance of several soybean varieties to root-knot nematodes (Meloidogyne incognita) Resistance of 19 soybean varieties to the root-knot nematode (Meloidogyne incognita) was evaluated in the green-house. One-week old seedling, in a plastic bag containing 4 liters soil of Segunung Andosol type, was infested with 500 second stage juveniles (L2) per 1000 cm cubic of soil. The experiment was arranged in a completely randomiz-ed design with three replications. Based on the reproductive index of M. incognita, two varieties (Wilis and Ringgit) were moderately resistant, 14 varieties were slightly resistant and three varieties (Muria, Malabal; and Lokon) were susceptible to M. incognita. The repmductive index of M. incognita on the varieties that were moderately resistant, slightly resistant, and susceptible were 12.75 - 23.65, 25.48 - 42.88, and 50.99 - 58.83%, respectively.
