The present study was conducted to find out correlation and path analysis for 10 yield and yield attributing traits using 159 diverse pea genotypes. Correlation studies revealed that the days to 50% flowering, node at which 1st pod appears, number of pods/plant, number of seeds/pod, pod length, pod weight and days to 1st picking had significant and positive correlation with total yield/plant while, plant height and shelling percentage were negatively correlated with total yield/plant. The inter-correlation was observed between days to 50% flowering, days to 1stpicking and node at which 1stpod appears; shelling percentage with number of seeds/pod and pod length; plant height with number of pods/plant and days to 1st picking. It is concluded that there is positive and inter-correlation of total yield/plant with the number of pods/plant, pod length, number of seeds/pod, days to 50% flowering, days to 1stpicking. The positive association suggested that selection should be oriented towards more number of pods per plant, pod length, more number of seeds per pod which would consequently leads to higher pod yield per plant. The Path analysis studies revealed that the number of pods per plant exhibit highest positive effect on yield per plant.
