| Abstract: |
| Multiple cropping system with wheat as a preceding crop has proven to be an available approach to enhance the land use efficiency．In this study different spring wheat varieties were compared the yields of succeeding crops such as corns on the cob radishes and Chinese cabbages were evaluated and finally the optimal double cropping patterns which could fully use agricultural climatic resources of Shenyang area were illustrated． The results showed that the preceding spring wheat varieties Liaochun 9and Shenchun 498 produced higher yield than others；corn on the cob varieties Funian1and Kennian1 performed better than others；Chinese cabbage varieties Qiuguan and Shiqiu had higher yields；radish variety Baiqiumeinong Chunlei and Hongfeng2 were high-yielding and expected to be promising in the multiple cropping system． |
