Relationships among morpho-phenological traits using principal components analysis in safflower
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2014, Vol 4, Issue 2
Abstract
Safflower (Carthamus tinctorius L.) is an oilseed crop which is adapted to semi-arid region of the world. The objective of this study was to use statistical method of principal components analysis to evaluate the relationship between morphological, phenological traits and yield performances of 20 different safflower genotypes. Plant characters such as day to initiate flowering (DIF), day to 50% flowering (50% DF), day to maturity (DM), plant height (PH), main head diameter (MHD), heads per plants (HP), seeds per head (SH), 1000-seed weight (SW) and seed yield per Plants (SYP) were main selected measurements for the data analysis. The information derived from principal components analysis could classify these characters into three groups based on the amount of variables among plant characters. These events enable to justify 80% of the all of variability within the genotypes. Number of head per plant, SW, SH, DF as well as DM are putative morphological markers which can be considered as the desirable tools for screening elite safflower genotypes for yield improvement in breeding of safflower.
