The path analysis of yeild and its components in safflower (Carthamus tinctorius L.)

Abstract

This study was aim to determine the relations among yield and some characters of safflower using correlations and path coefficient analysis. Fifteen safflower genotypes were grown at Van ecological conditions (eastern of Turkey) in 2000 and 2001 in randomized complete block design with three replications. Simple correlation analysis and path analysis were applied to the means of 15 genotypes in order to determine the relationships between agronomic characters and estimate the direct and indirect effects of agronomic characters on seed yield. Based on the results, positive and significant correlations were found between seed yield and all investigated traits except primary branches/ plant (r = -0.466**) and 1000-seed weight (r = -0.220*). According to the path analysis, it can be also that seed yield was determined by head diameter, heads/plant and seeds/head since these characters had highly positive significant direct effects on seed yield. © 2007 Asian Network for Scientific Information.
