This study aimed to assess oil yield components and their interrelationships of spring safflower lines
and varieties by using different statistical techniques to increase the oil yield in safflower breeding
program. Field experiments were conducted at the Transitional Zone Agricultural Research Institute
in Eskisehir, Turkey during 2014, 2015 and 2016. Correlation, simple linear regression, stepwise
multiple regression, path, principal component and cluster analyze were used to investigate the
relationships between oil yield and some components in spring safflower. The results revealed that
characters affecting oil yield, which is important to determine selection criteria in plant breeding,
vary according to statistical methods. Therefore, to obtain reliable result, it is essential to use
multivariate statistical methods for scanning significant characters in studied material. According to
the numbers of common characters determined in different statistical analyzes; oil content, seed
weight, seed yield and number of head per plant would be important selection criteria for improved
oil yield in the breeding material studied. The lines and varieties may be used in hybridization
program and their hybrids may yield more transgressive sergeants for these characters for oil yield
improvement.
