چکیده
A study was carried out to assess the genetic variability and association among yield attributing traits in 60 different safflower genotypes over six environments. The pooled analysis of variance (ANOVA) revealed that all attributes had a considerable degree variation.The parameters phenotypic coefficients variation (PCV) higher than genotypic (GCV)for characteristics evaluated, indicating experimental contributed total variation.Petal yield/plant seed highest PCV GCV followed by number capitula/plant, seeds/capitula, height insertion first branch, hundred weight, primary branches/plant, length longest branches, secondary branches up main capitula.Number yield/plant, petal seeds per capitula, upto capitulum diameter plant high heritability advance as percent mean. Seedyield/plant showed positive, significant directcorrelation with seeds/capitulum, capitulum, height, diameter, weight.Number capitula/planthad maximum direct effect on grain weight yield/plant. Hence selection these would improve breeding program. Keywords:Genetic variability, heritability, correlation, path analysis, Safflower

Effect of plant growth regulators on oil yield and biodiesel production of safflower (Carthamus tinctorius L.)
The aim of the present investigation was to determine the effect of plant growth regulators viz., kinetin, chlorocholine chloride (CCC) and salicylic acid (SA) on achene yield and oil quality of safflower (Carthamus tinctorius L.) cv. Thori pertaining to biodiesel production. The growth regulators were applied at 10M as foliar spray during flowering (140 days after sowing). Kinetin was highly e...

The F1 along with parents of a 4 x 6 line x tester crosses in safflower were studied and seven parameters, i.e., D 2 7 based on 7 characters and D24 based on yield and its 3 direct componenets and mid parent value (MP-Y), F1 mean (F1-Y), relative heterosis (RH-Y), biparental average GCA (MPGCA-Y) and SCA effect (SCA-Y) for yield were estimated. Twenty four selected crosses were studied for segr...

A Review of Fatty Acids and Genetic Characterization of Safflower (Carthamus Tinctorius L.) Seed Oil
Safflower, Carthamus tinctorius L., is an annual oilseed crop that is cultivated on small plots all over the world. The seed oil content ranges from 20% to 45%; the oil is high in linoleic acid, an unsaturated fatty acid that aids in lowering the blood cholesterol level. Thus, safflower has long been used as medical plant in many countries, especially in China and India. However, for industrial...
