The present study was carried out with the aim to determine genetic diversity in Salix alba germplasm/plus trees by employing the various catkin, seed and seedling characteristics. Divergence studies revealed grouping of 20 plus trees of S. alba into five clusters, with maximum plus trees in clusters I and II. There was maximum (748.77) cluster distance between clusters V and IV among all the clusters. This was followed by clusters I and IV (598.23). It indicates that there exists wide diversity between these groups. Cluster V had maximum for majority of the catkin, seed and seedling characteristics under study. The plus trees/genotypes in the clusters which are more divergent can be used for future breeding/tree improvement programmes of the species.
