Dimension, geometric, agricultural and quality characteristics of safflower seeds

Abstract

This research was carried out in the research field of Agricultural Faculty , Selcuk University , Konya, Turkey .Field experiments were carried out in two growing seasons (2011 and 2012) according to RandomizedComplete Block Design with three replications. In the study, a total of 13 promised safflower (Carthamustinctorius L.) lines (A13, A29, C12, E12, F4, F5, F6, G16, H3, J19, Y1 -8 -14 -1 , AOL-2(2), DP 1.5.8 -1) and 5cultivars (Black Sun1, KS 06 and Oleic Leed, Dinçer, Remzibey) were used as material. Oil content of thesafflower genotypes were rang ed in between 24.05 -33.18 %. The highest protein content value wa s obtainedfrom J19 line (21.72 %) while the lowest was found on the Turkish cultivar of Remzibey (16.03 %). Negativecorrelations were found for oil content and hull thickness (r=-0.3152**), hull ratio (r=-0.7122**) and pappusratio (r=-0.3408**). Protein content was found as significantly and negative correlated with some characters,similar to the seed widness (r = -0.2546**), seed thickness (r=-0.1918*), geometric diameter (r=-0.3194**), seedsurface area (r=-0.3119**), pappus ratio (r=-0.3114**) and 100 -seed weight (r=-0.2597), respectively.According to the results, increasing the dimension and geometrical values cause to a decrease in the oil andprotein content of safflower seeds. Quality components (oil and protein content) showed negative correlationswith both of pappus rate and hull features.
