Identification of putative trait based markers for Genetic Improvement of Eucalyptus tereticornis
نویسندگان
چکیده
Tree breeding is basically aimed at producing quality products like seeds and clones and the most valuable contribution of molecular markers in breeding programs would be to reduce the time of selection or to reduce the number of breeding cycles. This can be achieved either by the early identification of superior progeny or by the identification of parents that will yield superior progeny. The present study highlights the use of microsatellite markers towards development of putative markers tagging the adventitious rooting trait in Eucalyptus tereticornis. Further, putative cellulose synthase specific markers were identified and correlated with pulping character of wood tissues. The validation of these putative markers in larger populations can lead to more efficient and broadly applicable early selection procedure for key traits in eucalypt breeding programs.

متن کاملSpecies 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. Our goal was to evaluate the use of simple sequence repeat (SSR) loci for species dis...
متن کاملDetermination of inter- and intra-species genetic relationships among six Eucalyptus species based on inter-simple sequence repeats (ISSR).
Eucalyptus is the most economically important hardwood plantation tree cultivated in tropical and subtropical countries. Inter-simple sequence repeat (ISSR) markers were used to evaluate genetic relationships within and between individuals of six Eucalyptus species. A total of 583 loci (265 to 1535 bp) were amplified from 149 individuals belonging to the six Eucalyptus species using seven ISSR ...

Flowering period and longevity play important roles in determining the quality of commercial flowers. Marker-trait associations for eight flowering and 12 ornamental traits have been studied using a GLM and MLM analysis with a set of 2099 AFLP polymorphic markers in Chrysanthemum. The GLM model identified 453 markers for phenotypic traits whereas the MLM association analysis model revealed a t...

Background Eucalyptus globulus is the most planted hardwood species for pulpwood in temperate regions. Genomic researches in Eucalyptus have increased the information available in DNA sequences public databases and several structural and regulatory genes involved in the cellulose and lignin pathways are known. Functional genetic markers, while frequent in crop, are still scarce in forest specie...
