p=0.05level of significance, while axis persistence has showed no significant difference. Genetic analyses showed heritability estimates for the characters axis persistence and straightness (below 15%) while moderate estimates of heritability for height, GGL and GBH (between 40.60%). It is suggested that selections could be made from superior trees of individual provenances in order to have broad base for genetic improvement of Casllarina equisetifolia in Andhra Pradesh.

The International Provenance trial of Casuarina equisetifolia was established in 1996, with 27 provenances in Regional Forest Research Centre, Rajahmundry, East Godavari District, Andhra Pradesh. The Australian Tree Seed Centre of CSIRO, Canberra, Australia coordinated in collection of seed throughout the natural range as well as from land race populations of Casuarina. The Analyses of Variance of data indicated significant difference among provenances for height, GGL, GBH and straightness ap=0.05level of significance, while axis persistence has showed no significant difference. Genetic analyses showed heritability estimates for the characters axis persistence and straightness (below 15%) while moderate estimates of heritability for height, GGL and GBH (between 40.60%). It is suggested that selections could be made from superior trees of individual provenances in order to have broad base for genetic improvement of Casllarina equisetifolia in Andhra Pradesh.

At Regional Forest Research Centre, Rajahmundry, East Godavari District, Andhra Pradesh the genetic improvement of Casuarina was commenced in 1994 and to date, considerable work under this project has been done, Candidate Plus Trees have been selected and established progeny tests. The progeny test comprises 16 families (16 CPTs) selected in North Coastal districts of Andhra Pradesh. In progeny test, the data was recorded at 24 months age for plant height, girth at ground level, girth at breast height, axis-persistence and straightness which showed great variation among the families. The characters Ggl, Gbh and straightness are showing significance at P⋍ O.05 level of significance. The broad sense heritability and genetic advance were calculated for all the parameters recorded and are presented. The interim results of this trial suggests that the further selections can bc made after monitoring the experiments for 3 to 4 years.- Rooting of Stem Cuttings of Wrightia tinctoria (Roxb.)
