In order to estimation genotypic correlation and heritability of some faba bean traits, 26 faba bean
genotypes were evaluated in a randomized complete block design with three replications during 2014-
16 growing seasons in Agricultural Research Sation of Borujerd located in Lorestan province, Iran.
The restricted maximum likelihood (REML) was used to estimate the genotypic and phenotypic
correlations, broad sence heritability and genetic gain. Analysis of variance based on least squares and
REML indicated significant effect of genotype on days to maturity, plant height, hundred seed weight,
pod length and dry seed yield. Genotype×year interactions were significant on all of the traits except
of pod length. Borujerd cultivar (G26) and G20 had the highest dry seed yield in both of years. REML
results indicated a significant positive genetic correlation between dry seed yield and biological yield
and plant height. Also, there were a significant negative phenotypic correlation between dry seed yield
and days to maturity, and significant positive phenotypic correlation between dry seed yield and plant
height, biological yield and harvest index. So, the selection of early maturing genotypes with a higher
yield is achievable and selection can be done to improve the performance of dry seed yield. Cluster
analysis indicated variability among genotypes. According to values of broad sence heritability and
genetic gain for plant height and high genetic correlation of this trait and dry seed yield; plant height
can be used as a suitable trait for improving dry seed yield by selection.
