摘要

这项研究于2017年至2019年期间在卡格拉查里（Khagrachari）巴里（BARI）山区农业研究站进行。研究从 Khagrachari 的 HARS 现有咖啡果园中选取了 30 个基因型的 Coffea canephora（同义 Coffea robusta）（俗称 robusta 咖啡）。被评估品系（CC Kha 001）的平均高度为中等（4.31 米），为小乔木灌木。叶片的平均宽度和长度分别为 9.2 厘米和 20.86 厘米，叶柄长 1.6 厘米。单个果实的平均宽度和长度分别为 1.28 厘米和 1.16 厘米，厚度为 1.06 厘米。浆果的采收期为 1 月中旬至 2 月中旬。受测咖啡植株（CC Kha 001）的种子颜色为绿褐色，形状呈圆形。单粒种子的平均长度和宽度分别为 1.09 厘米和 0.99 厘米，厚度为 0.75 厘米。100 粒种子的平均重量为 100.33 克。每个树干的平均浆果重量（千克）为 8.08（千克/树）。

Performance Evaluation of Coffee Coffea canephora (syn. Coffea robusta) Germplasm in the Hilly Region

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 height of evaluated line (CC Kha 001) was medium (4.31 m) and regular bearing shrub of small tree. The average width and length of leaf was 9.2 cm & 20.86 cm respectively with 1.6 cm of leaf petiole length. 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).
