“…Subramanian et al (1995) reported that height, clear bole height, girth, diameter and basal area showed moderate heritability and genetic advance in Eucalyptus grandis. Pande et al (2013) also found high heritability coupled with moderate level of genetic advance and genetic gain for girth at breast height, specific DBH = diameter at breast height, SG = specific gravity, FL-fibre length, FD = fibre diameter, FCWT = fibre cell wall thickness, VL = vessel length, VD = vessel diameter, VF = vessel frequency gravity and height in L. leucocephala. The rest of the characters in this study showed moderate/low heritability with low genetic advance, indicating the presence of non-additive gene action.…”

“…For specific gravity, genotypic coefficient of variation and environmental coefficient of variation were almost the same and there was considerable intergenotypic variation existing for further genetic improvement. Pande et al (2013) reported higher environmental coefficient of variation for all the traits in L. leucocephala except specific gravity and DBH than their corresponding genotypic coefficient of variation. Heritability is defined as the degree to which a character is influenced by heredity compared with the environment.…”

“…Inter-and intra-cluster distances calculated were presented in Table 3. Hybridisation between the populations selected from diverse clusters is expected to express higher heterosis and produce desirable recombinants and transgressive segregants (Pande et al 2013).…”

“…This technique has been effectively applied to distinct populations of Eucalyptus camaldulensis and Acacia nilotica (Burley et al 1971, Bagchi 1992. Divergence studies analyse the degree of diversification and relative proportion of each component character to the total divergence, which measures the forces of differentiation at intra-and inter-cluster levels (Pande et al 2013). Assessing all available genetic variations or divergence within/between species and delineation of best genotype matching to the site for increased productivity is of prime important in any tree improvement programme (Sharma & Bakshi 2014).…”

Forty-six Casuarina equisetifolia clones were evaluated for growth and wood parameters to study their genetic divergence. The clones were grouped into seven clusters using Mahalanobis D 2 analysis. Vessel frequency contributed maximum (51.50%) towards divergence followed by specific gravity (16.23%). Maximum intercluster distance was observed between clusters 3 and 5 (14.58) followed by clusters 5 and 7 (12.098). Intracluster distance was maximum in cluster 5 (9.225) followed by clusters 6 (8.991), 7 (8.068) and 1 (7.700). Highest value of heritability, genetic advance and genetic gain were obtained for specific gravity, fibre length and volume respectively. Both phenotypic coefficients of variation (PCV) and environmental coefficients of variation (ECV) were highest for vessel frequency, while genotypic coefficients of variation (GCV) was highest for volume. ECV was observed to be higher than GCV for all the traits showing the influence of environmental factors on these traits. The results on genetic divergence had potential for immediate application in the establishment of clonal seed orchards. Information on genetic divergence provides an opportunity for hybridisation among the genotypes and obtaining quality seeds with high vigour.

Genetic variability of growth, wood density and fibre characters was determined in twenty second-generation clones of Acacia auriculiformis grown at IFGTB-Field Research Station, Neyvli, Tamil Nadu, India. Total volume revealed high phenotypic (29.10 %) and genotypic coefficient of variation (31.30%). Moderate PCV and GCV values were observed for height, fibre lumen diameter, Runkel ratio, slenderness ratio and wood density. The volume and fibre lumen diameter had high heritability 86 and 76 per cent, respectively. Fibre length, Runkel ratio, slenderness ratio and rigidity coefficient showed high heritability coupled with high to moderate genetic advance. Twenty clones was formed into four clusters by D2 analysis. Maximum inter-cluster distance was recorded between cluster II and cluster IV (7.396) and minimum inter-cluster distance was recorded between clusters II and IV (3.364). Higher intra-cluster values were observed in clusters I (4.171) and lower values in cluster III (3.179). Selection of clones based on clusters provides an opportunity for further improvement of growth and wood quality.
