Yield performance and selection of F1 hybrid Liberica coffee

M. Muhamad Ghawas

Abstract

In an evaluation of 1 350 F1 hybrid progenies of Liberica coffee, 20 individual plants with yield indices between 3.04–5.74 have been identified and selected. All of them showed higher 100-fresh berry and green bean weights as compared to the current clonal standards. Their respective 100-fresh berry and green bean weights of 550.6–932.3 g and 30.08–39.91 g were about 0.75–70.59% and 6.10– 40.78% heavier. The respective weights of the current clonal standards were 546.5 g and 28.35 g. The criteria and basis of selection were also discussed. These selected potential progenies have been multiplied vegetatively and maintained in the germplasm area at MARDI Kluang, Johor awaiting for future clonal evaluation.
