Cultivar Release, Padideh, A New Safflower Cultivar

Authors

Abstract

Research was conducted to develop and release new improved winter safflower (Carthamus tinctorius L.) cultivar suitable for cold and semi cold areas of Iran.In 1995,1996 and 1997, line L.R.V.51.51 was selected from Uromeieh landraces based on agronomic traits, resistance to diseases and abiotic stresses under field conditions .It was included in yield trials in main Research Stations Karaj ,Isfahan and Darab, together with 9 safflower lines, as well as widely grown improved cheek cultivar Zrgan-279 Results showed that this line produces significantly higher and stable yield. Analysis of the grain and oil yields using Eberhart and Russel method showed significant difference for the main effects of genotype and genotype × environment (linear) interactions and non- significant difference for deviation from regression. According to the classification of genotypes based on the mean of grain and oil yields, coefficient of regression and deviation from regression, the new line L.R.V.51.51 with its high grain and oil yields and stability was selected as a desirable genotype while it has more tolerant to cold than Zargan-279, with mean grain and oil yields 2205 Kgha-1 and 600 Kgha-1 respectively. The new line was released in 2005, under the name of Paideh.
