MIRASSON, HR; PALOMO, IR; BREVEDAN, RE  e  FIORETTI, MN. Yield and stability of safflower varieties (Carthamus tinctorius L.) in the Semiarid Pampean Region. Phyton (B. Aires) [online]. 2011, vol.80, n.2, pp.147-151. ISSN 1851-5657.

Safflower production is mainly concentrated in northwestern Argentina although the most suitable area for its production is the central, Semiarid Pampean Region. The response of different varieties able to produce high sustainable yields was studied under different environments, with the idea of promoting these varieties in the study region. Six variety trials were carried out at two locations in the study area, Santa Rosa (La Pampa, 36° 39' S, 64° 16' W) and Tres Picos (Buenos Aires, 38° 16' S, 62° 13' W), during several years. Relative yield was used as a measure of safflower stability. Varieties S-541, S-200 and S-400 were the most stable and showed the highest grain and oil yields.
