Abstract
A pot experiment was conducted to study the effects of reciprocal hybridization on cadmium (Cd) accumulation in F1 hybrid of Solanum diphyllum and Solanum nigrum by Cd treatment (the final soil Cd concentration was 10 mg/kg). The results showed that the Cd content of F1 hybrid was between the parents. In stems, leaves and shoots, the Cd content of DN (S. diphyllum male × S. nigrum female) and ND (S. nigrum male × S. diphyllum female) F1 hybrid increased by 14.09% and 17.34%, 8.08% and 11.14%, 9.5% and 12.04% respectively compared with S. nigrum, and decreased by 13.34% and 10.87%, 6.52% and 3.88%, 7.44% and 5.0% respectively compared with S. diphyllum, with no significant difference in roots. Therefore, the accumulation ability of Cd in F1 hybrids was improved to a certain extent compared to S. nigrum, but decreased to a certain extent compared to S. diphyllum.
