Performance of five arabica coffee selections in Karnataka and Tamilnadu zones
A survey was undertaken to assess the performance of five arabica coffee cultivars viz. S.795, Sln.5, Sln.6, Sln.8 and Sln.9 in different agroclimatic zones of Karnataka and Tamil Nadu. The survey showed varied performance of different cultivars in various zones. In Chikmagalur zone, S.795, Sln.5 (S.2931) and Sln.9 were the top performers compared to other selections whereas, in Aldur/Mudigere, Sakleshpur/Somwarpet and South Coorg zones, Sln.5, 6 and 8 showed better performance. In Pulneys (T.N.), Sln.5 (S.2931), Sln.6 and Sln.9 were the best performers. In Shevaroys, S.795 and Sln.9 averaged higher than others. Considering the performance over all the zones, Sln.8 and S.795 indicated better yield response to favourable environment while, Sln.5 showed marginal response. Sln.6 and Sln.9 revealed average response. The differential performance of the cultivars is attributed to the interaction between their genetic compliments and the environment.
