Genetic Divergence between Half-sib Families under Different Environments in Albi ia lebbeck Benth

Ten half-sib progenies of Albi ia lebbeck belonging to different places of Allahabad regions were sown in glasshouse and field condition with a view to assess the impact of two different environments on the expression of genetic diversity using non-hierarchical Euclidean cluster analysis. Superior tree progenies were grouped into four clusters under glasshouse as well as in field atmosphere. Families of plus tree S₉ and S₁₀ formed one cluster both under glasshouse and field back ground. Inter cluster distance was found to be highest between cluster IV and II (59.06) under green house whereas, under field condition cluster III and I showed maximum (51.80) inter cluster distance. Within a cluster showed low intra-cluster distance <1.681), under both the environments, revealing their genetic closeness. Leaf area followed by seedling height contributed maximum to the total divergence and played a predominant role in creating the genetic diversity.
