Abstract

Safflower with high grain oil quality and good tolerance to environmental stresses can be important for oil seed production. A good source of useful genes for improving cultivars of this plant species is its wild relatives. This experiment was conducted to assess the genetic variation and tolerance to DROUGHT STRESS in F3 families derived from a cross between domesticated (Carthamus tinctorius L.) and wild (C.oxyacanthus L.) safflower species using a randomized complete block design with three replications under DROUGHT STRESS and non-stress conditions. High heritability was observed for the studied traits including: days to flowering, days to physiological maturity, plant height, number of branches per plant, number of head per plant, number of grain.head-1, 1000-grain weight and grain yield. The highest genetic coefficient of variability belonged to grain yield per plant (41% and 36% in stress and non-stress conditions, respectively). Transgressive segregation was also observed among the F3 families in both directions and both conditions for most of the traits. The presence of significant genotype by environment interaction for the studied traits implied different reactions of families to DROUGHT STRESS and non-stress conditions. Family 36 with high yield in both stress and non-stress conditions and low reduction in grain yield under DROUGHT STRESS was identified as the superior family. Result of this experiment indicated that there are possibility of improving drought tolerance in safflower genotypes using inter-specific corssing with Carthamus oxyacanthus L.
