Heritability, potential ratio, and heterosis of soybean (Glycine max [L.] Merrill) resistance to soybean mosaic virus.The use of soybean cultivars with resistance to SMV is a beer button down shirts for men way for controlling soybean mosaic disease.

The objective of this research was to estimate the disease severity, the narrow sense heritability, potential ratio and heterosis of resistance character and number of pithy pods, number of healthy seeds, and healthy seeds weight per plant of ten F1 populations of soybean crossing result to SMV infection.The experiment was arranged in a randomized complete block design in two replications.Observed characters were disease severity, number of pithy pods, number of healthy seeds, and healthy seeds weight per plant.

The result of this research showed that 1) the crossing combinations those which were resistant hp pavilion 15-eg1053cl to SMV (lower disease severity) were Yellow Bean x Tanggamus, Tanggamus x Orba, and Tanggamus x Taichung, 2) the narrow sense heritability of disease severity was included in medium criteria, 3) number of pithy pods belonged to high criteria, and 4) number of healthy seeds and healthy seeds weight per plant were included in low criteria.The crossing combinations that had low estimation value of heterosis and heterobeltiosis of resistance to SMV infection were Yellow Bean x Taichung, Bean x Tanggamus and Tanggamus x B3570.Disease severity or resistance to SMV is influenced by genetic and environmental factors.
