Abstract
Arabica coffee is one of export commodities that contribute income to Indonesia economic. Coffee conversion program from robusta to arabica requires reliable seedling technology. Grafting is one of seedling technologies that can be carried out during the early stage of plant growth, in which robusta serves as the rootstock and arabica as the entrees. This experiment was conducted at Agriculture Experimental Sites of Agriculture Faculty, University of Bengkulu from May to September 2003. Treatment consisted of seven grafted combinations of robusta and arabica coffee that planted in three different growing media. Experiment was arranged in Randomized Block Design with three replications. Observations were addressed to the seedling growth traits. Analysis of variance, estimated variance, coefficient of genetic variability, and estimated heritability were performed in the data analysis. Result indicated that genetic variances of couple-leaf weight and root length traits were greater than environmental variance. Couple-leaf weight and couple-leaf area had high coefficients of genetic variability. In adidition traits of couple-leaf weight and leaf length and root number had high estimated values of heritability. For selection indicators of four month old of seedling, it is recommended to use couple-leaf weight and root length traits.
