Thirty-two half sib progenies of Kachnar (Bauhinia
variegats L.) belonging to different geographic regions of
Himachal Pradesh, Haryana, and Jammu & Kashmir were
sown in glasshouse and field condition during 2004 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 ten and eight clusters in
glasshouse and field atmosphere, respectively. Families
of plus tree T5 and T6 formed one cluster both under
glasshouse and field back ground. Whereas, T3 and T9;
T
19 and T2; T17 and T1S; T15 and T22; T15 and T1S; T30
and T31 , formed same group but different clusters. Intra
cluster distance only under glasshouse condition was
zero for cluster II, VI and X. The highest inter cluster
distance was found between cluster X and III (12.293,
under glasshouse), cluster IV and I (7.325, under field
situation). Seedling height contributed maximum to the
total divergence and played a predominant role in creating
the genetic diversity.
