Abstract:
The present research was conducted for evaluating different Arabica coffee genotypes for yield and quality parameters during the year 2020-21 and 2021-22 at Central Coffee Research Institute, Balehonnur, Karnataka, India which in turn help in identifying high yielding varieties in Coffea arabica L. About 41 arabica coffee genotypes were used comprised of 39 exotic collections along with two check varieties such as Cauvery and Chandragiri (CCRI, selections). Results from the experiments revealed that significant variation among the genotypes were observed for clean coffee yield and caffeine content. Clean coffee yield was ranged from 418.42 to 474.18 kg/ha (2020-21) and 268.98 to 627.63 kg/ha (2021-22), similarly caffeine content was ranged from 0.56 to 1.05 per cent. Genotypes S.2724, Chandragiri, S.2532, S.1655, S.2608, S.2725, S.2502 and S.1482 established higher clean coffee yield per ha, while the genotypes S.1477,S.2602, S.1573, S.2532 and S.1655 revealed low caffeine content. Therefore these genotypes can be selected as these genotypes will serve as resource for further crop improvement programmes like breeding for high yield combined with low caffeine content.
