摘要

[Objectives] The rice varieties with a low cadmium (Cd) content and a high yield were screened to provide reference for further experiments on moderate and high Cd-contaminated soils and local promotion.[Methods] Under the soil condition of a Cd content of 0.58mg/kg,differences in agronomic traits such as grain Cd content,yield,number of effective panicles,number of grains per panicle and 1 000-grain weight of 26 different rice varieties such as Huanghuazhan,Y Liangyou 9918 and T You 109,were studied by pot experiment.[Results] Such six varieties as Xiangyou 109,Tianfengyou 316,C Liangyou 651,Y Liangyou 3218,Y Liangyou 9918 and T You 109 had a relatively higher yield and relatively lower Cd content,which was because that their traits including panicle length,number of effective panicles and 1 000-grain weight were superior to other varieties.The correlation analysis between plant Cd content and yield showed that there was a negative correlation between Cd content and yield in rice.[Conclusions] This study provides a theoretical basis for cultivating suitable varieties in this area.
