Abstract Growth and development of safflower are affected by different uncontrollable environmental conditions. Oil contents of safflower are largely influenced by temperature fluctuations. Temperature variations in the field can be created by sowing crops at different dates in the season. The objective of this work was to investigate the effect of different planting dates (i.e., 1st November, 15th November and 1st December), and thermal temperatures (growing degree days, GDD) on yield and quality traits of four genotypes (two local land races, i. e. G 21 and G 81 and two exotic genotypes from Cyprus i. e. G 45 and G 48) and a commercial cultivar (Giza 1). Six environments were created (three different planting dates during 2006/07 and 2007/08) |
