Determination of Cross-Pollination in Safflower (Carthamus tinctorius L.) Using Different Experimental Designs

Abstract

This study was carried out at the University of Ankara, Faculty of Agriculture and Field Crops Department experimental field during 2012-2013. Two safflower (Carthamus tinctorius L.) cultivars having two different characters (spiny and spineless) were used as the study material. The cultivars with spiny (Balcı) was used as a donor and spineless cultivar (Yenice) was used as a receptor. Average cross-pollination ratio ranged between 1.12% and 7.72%. The highest cross-pollination ratio was obtained from third experimental design while the lowest ratio was in north direction of forth experimental design. General average ratio was 3.49% in Ankara conditions. There were differences among the experimental designs in respect to cross-pollination. The results of this research showed that cross-pollination ratio decreased when distance between donor and receptor plants increased.
