Relationships between selected traits in maize (Zea mays L.). Part 1. Linear and rank correlations
Journal Title: Journal of Research and Applications in Agricultural Engineering (ISSN 1642-686X) - Year 2019, Vol 64, Issue 3
Abstract
The objective of this study was to assess the relationships between grain yield and selected traits in maize linear Pearson correlation coefficients and Spearman’s rank correlation coefficients. The study comprised of 13 maize cultivars, evaluated at two years in a randomized complete block design, with four replicates. The linear and rank correlation coefficients were shown in tables and as figures for easier observation of their tendency and significance.
