摘　　要：为筛选耐缺铁花生种质,在四川盆地东北部的石灰性紫色土上,对19个花生品种的耐缺铁性进行鉴定,结果表明:1)花生在不同生育时期的耐缺铁性差异较大,结荚期表现最为明显;2)花生品种间耐缺铁性差异显著,ICGV86031无缺铁性黄叶及矮化株,SPAD值最高;3)品种间的耐缺铁性变异和丰产性变异表现为极显著的二次曲线相关或简单直线相关;4)ICGV86031极耐缺铁、但丰产性差,ICGV97228、ICGV97229和ICGV97232为铁敏感材料,在缺铁性土壤上产量损失严重,天府24较耐缺铁且产量高。The lime induced iron deficiency chlorosis of peanut occurs commonly in calcareous,alkaline and purplish soils of Sichuan Basin.Iron-deficiency induced chlorosis tolerance of 19 peanut genotypes were investigated in 2010 and 2011.The results showed that： 1） the occurrence rate of the chlorosis were significantly different among the developmental stages and maximized at 75 days after sowing date at pod setting stage;2） the tolerance to iron deficiency among 19 genotypes were markedly different,the genotype ICGV 86031 was free from the symptoms and had maximum SPAD;3）the variances of the chlorosis tolerance and yield among genotypes had significant quadratic parabola or linearity correlation at 1% probability level;4） ICGV 86031 was iron efficient,but low yielding,while ICGV 97228,97229 and 97232 were iron sensitive and had the most yield reduction in the calcareous and purplish soil.Tianfu 24 tolerated iron deficiency well with higher yield.
