CORRELATION AND PATH COEFFICIENT ANALYSIS FOR SOME EAR YIELD RELATED TRAITS IN POPCORN (ZEA MAYS VAR. EVERTA)

Abstract

The aim of this study is firstly to determine the suitable observations in popcorn breeding researches. And secondly aim is to identify all the possible interaction between grain yield and yield component in popcorn with correlation and path coefficient analysis. The experiments were designed in a randomized block design with 3 replicates. These experiments were conducted in Samsun, Turkey in 2014 and 2015. The results unveiled a significant and positive correlation between grain yield and the all component. The greatest positive effect on grain yield are yield per ear, grain yield per ear and grain moisture according to the path analysis, respectively. The presented results have demonstrated the potential of privileged of observation yield per ear, grain yield per ear and grain moisture thus increasing yield in popcorn.
