Abstract

Correlation coefficient indicates only size and sign of relationship between traits. Path analysis can determine direct and indirect effects. Thus, plant breeders use path analysis to identify effective traits on yield. An investigation was conducted in unbalanced CRD including 27 genotypes (7 Poa species) collected from different parts of Zanjan province. Significant relationship was found by simple correlation coefficient among yield and traits, including spike weight, stem weight, spike length, pollination date, flowering date, stem number and leaf to stem ratio. After regression analysis, number of effective traits reduced to four traits, including spike weight, fresh forage weight, crown diameter and plant height. Final equation explained 96 percent of total variation. Eventually, path analysis showed that spike weight and fresh forage weight had the most direct effect on yield.
