<![CDATA[Soybeans(Glycine max (L.) Merill) is an important food crop that served as an alternative source of protein in Indonesia, due to its very high grain protein content ranging from 40% to 50%. This research is intended to determine genotypic variance components, and heritability of important characters in a soybean population at two planting space. The field experiment was conducted using a randomized block design with 3 replications. Six varieties including Argomulyo, Anjasmoro, Kaba, Burangrang, Gema, Grobogan and three line including KM1, KM-12 and KM25 were grown with two spacing plants, ie, 40cm x 20 cm and 40cm x 15 cm in a plot measuring 3 m in lenght and 2 m in wide. Characters Observed were plant height, flowering date, harvesting date, seed number per plant, grain weight per plant, 100-grain weight, and grain yield m-2. Generally,the result indicate that all characters vary greatly among genotypes but not significantly different between planting space. Specificaly, genotypes showed high variability in flowering date, harvesting date, grain yield m-2 and 100-grain weight, but not for other traits. The value of genotypic varian components was different from 0 only for flowering date, harvesting date, grain yield m-2 and 100-grain weight. Heritability estimated were diffrent from 0 for flowering date, harvesting date, grain yield m-2 and 100-grain weight, but not for other characters. Keywords : soybean, variability, varians component , heritability]]>
