Abstract

The study was conducted at the Hill Agricultural Research Station, BARI, Khagrachari during the year 2017 to 2019. Thirty (30) genotype of Coffea canephora (syn. Coffea robusta) commonly known as robusta coffee from the existing coffee orchard of HARS, Khagrachari was selected for the study.

The average width and length of individual fruit was 1.28 cm & 1.16 cm respectively with 1.06 cm of thickness. Harvesting duration of fruit berry was mid-January to mid-February. The seed colour of evaluated coffee plant (CC Kha 001) was greenish brown with roundish shape. The average length and width of individual seed was 1.09 cm & 0.99 cm respectively with 0.75 cm of thickness. Average weight of 100 been was 100.33 gm. Average berry weight (kg) per trunk was 8.08 (kg/tree).
