Quantitative genetic analysis of wood property traits in biparental population of × .

breeding programme mainly aims at increasing productivity associated with wood property traits which are suitable for different end uses. The principal challenge in this endeavor is to combine productivity with industrially relevant wood traits. In the present study, 23 hybrid clones derived from a biparental mapping population of × was assessed for six wood property traits across two sites in Tamil Nadu, India.

Diversity of bacterial endophyte in Eucalyptus clones and their implications in water stress tolerance.

The genus Eucalyptus with over 747 species occurs in wide ecological range and is preferred for bioenergy plantations due to their short rotation, rapid growth and superior wood properties. They are planted in 22 million ha area and India is third largest planter of Eucalyptus. In the present study, the bacterial endophyte community in leaves of six Eucalyptus clones belonging to E.

Genetic linkage map and QTL identification for adventitious rooting traits in red gum eucalypts.

The eucalypt species, and , show tolerance to drought and salinity conditions, respectively, and are widely cultivated in arid and semiarid regions of tropical countries. In this study, genetic linkage map was developed for interspecific cross  ×  using pseudo-testcross strategy with simple sequence repeats (SSRs), intersimple sequence repeats (ISSRs), and sequence-related amplified polymorphism (SRAP) markers. The consensus genetic map comprised totally 283 markers with 84 SSRs, 94 ISSRs, and 105 SRAP markers on 11 linkage groups spanning 1163.

Species discrimination, population structure and linkage disequilibrium in Eucalyptus camaldulensis and Eucalyptus tereticornis using SSR markers.

Eucalyptus camaldulensis and E. tereticornis are closely related species commonly cultivated for pulp wood in many tropical countries including India. Understanding the genetic structure and linkage disequilibrium (LD) existing in these species is essential for the improvement of industrially important traits.
