Comparison of Relationship of Some Traits of Soybean (Glaycin max L.) Genotypes

In order to determination of different soybean genotypes on the quantitative and qualitative yield, The experiment was conducted in randomized complete blocks design (RCBD) in two replications at Agricultural College of Guilan University in 2008. Result of analysis of variance showed that there were significant difference among the studied soybean genotypes in the majority of traits. Results correlation analysis showed that grain yield per plant had significant and positive correlation with all studied traits. The highest positive correlation were observed between day to %50 flowering and day to maturity (r = 0.966**) and between fresh & dry weight of plant (r = 0.939**). The results compare means showed Between genotypes significant difference were exists and data recorded in showed that Grain yield increased across the soybean genotypes. The minimum Grain yield was recorded in the Union genotype. The maximum Grain yield was recorded in Hamilton genotype.
