Association of Agronomic Characters in Robusta Coffee (Coffea canephora Pierre ex Froehner)
K.R. Nikhila, V.B. Sureshkumar, K.V. Mohanan and A. Santaram

Abstract:
A study has been taken up in robusta coffee (Coffea canephora Pierre ex Froehner) to analyse the association of agronomic characters by factor analysis using 28 characters by principal component analysis. Five factors were obtained and the 28 characters under study could be grouped into five groups. Bush spread, length of primary branches and girth of primary branches were found to be the lead characters in the first group, out turn (fresh to clean coffee) the lead character in the second group, internode length the lead character in the third group, out turn (fresh to dry) the lead character in the fourth group and number of primary branches the lead character in the fifth group. These characters could be used as lead characters in selection and other plant breeding programmes in robusta coffee so that the bulk of variables for analysis could be reduced without compromising the outcome.
