Vascular tissue which is arranged in vascular bundles have an important role in increasing yield of soybean. In plant breeding, heritability, and inheritance of a character are important genetic parameters in selection and in incorporation of important characters into a single genotype. The objectives of this study was to determine heritabilities estimates and inheritance pattern of number of vasvular bundles in soybean. Field experiments were conducted at Agricultural Research, Training, and Development Station (SPLPP), Faculty of Agricultue, Padjadjaran University, Arjasari, Bandung (960 m above sea level, ultisol, with pH 5.7 and 'B' type of rainfall according to Schmidt and Fergusson classification), during April 2003 - August 2003. The result of experiments showed that broads sense heritability estimates for number of vascular bundles in segregating populations were 0.40 in population I and 0.48 in population II. Narrow sense heritability estimates were 0.32 in population I and 0.46 in population II. Inheritance pattern of number of vascular bundles followed a simple Mendelian inheritance with 3:1 ratio, indicating that number of vascular bundles was controlled by at least a pair of genes with additive and dominance effect.
