The safflower (Carthamus tinctorius L.) is an oil seed crop from which the flowers is used as medicine and food colorants. The present investigation was undertaken to explore gene effects for safflower's pigments in flower including carthamin and carthamidin. Six generation including P, P, F, F, BC and BC that derived from two different crosses (Mex. 2-138 (P) × Wht-Esf (P) and C111 (P) × Wht-Esf (P) were used for generation of mean analysis. The joint scaling test showed that additive [a], additive × additive [aa], and additive × dominance [ad] effects were significant for genetic control of carthamin and carthamidin in both crosses. The traits, including carthamidin and carthamin, had medium (48%) and low (17%) narrow-sense heritability, respectively. The results obtained here could be suitable for designing the breeding strategies based on selection to improve carthamin and carthamidin pigments in safflower.
红花（Carthamus tinctorius L.）是一种油料作物，其花可作为药物和食用色素。本研究旨在探讨红花花中色素（包括红花素和红花红苷）的基因效应。利用两个不同杂交组合（Mex. 2 - 138（P1）×Wht - Esf（P2）和C111（P1）×Wht - Esf（P2））衍生的六个世代（P1、P2、F1、F2、BC1和BC2）进行均值分析。联合尺度检验表明，在两个杂交组合中，加性效应[a]、加性×加性效应[aa]和加性×显性效应[ad]对红花素和红花红苷的遗传控制均显著。红花红苷和红花素性状的狭义遗传力分别为中等（48%）和低（17%）。本研究结果可用于设计基于选择的育种策略，以提高红花中红花素和红花红苷色素的含量。
