One hundred and sixteen forage type hybrid parents (seed and pollinator parents) were investigated at International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), India, in summer seasons of 2015 and 2016 for estimating inter-relationships between forage quantity and quality traits and their direct and indirect effects. Significant negative correlation but of low value was found between crude protein (CP), In vitro organic matter digestibility (IVOMD) and dry forage yield (DFY).  The direct and indirect effect of these forage quantity related traits on the DFY and other forage quality related traits on IVOMD was investigated in pearl millet. Path analysis revealed that total green forage yield (TGFY) had highest positive direct effect on DFY for forage quantity traits followed by plant height (PH). For forage quality traits, metabolizable energy (ME) had highest direct effect on IVOMD in both the cuts. CP and cellulose also had positive direct effects on IVOMD in both the cuts.

Key words: Dry forage yield (DFY), Green forage yield (GFY), Metabolizable energy (ME), In vitro organic matter digestibility (IVOMD)
