Abstract

Correlations and path analysis were worked out in three-year-old progeny trial of five different Prosopis species viz. P nigra, P chilensis, P flexuosa, P alba and Prosopis species - preuvian. All the correlations between plant height, collar diameter, crown diameter and biomass were found to be positive. Correlation coefficients were the maximum between plant height and collar diameter and ranged from 0.79 (Pchilensis) to 0.87 (Prosopis species - peruvian). Path analysis revealed that maximum direct effect towards biomass was contributed by collar diameter in P nigra (0.48), P alba (0.36) and Prosopis species – peruvain (0.38). However, in case of Pchilensis plant height had maximum direct effect towards biomass (0.36). In P flexuosa, crown diameter contributed maximum in this respect (0.51). Residual effects were high in all the cases and ranged from 0.56, in P chilensis to 0.73 in P flexuosa.
