摘　　要：[目的]为筛选适宜沿江高沙土地区种植的高产高抗玉米新品种。[方法]以焦点玉1303、浚单20、苏玉23等8份玉米品种及苏玉29(对照)为供试材料,研究其在沿江高沙土地区的主要农艺性状、产量结构、抗逆性等生育特性。[结果]各品种全生育期均短于对照,其中浚单20的全生育期最短,为118 d;苏玉41产量最高,为9363.9 kg/hm^2,焦点玉1303次之,为9308 kg/hm^2,较对照分别增产12.22%、11.55%;春风886、苏玉20、苏玉41果穗千粒重分别为375、353、313 g,均显著高于对照,但苏玉23的千粒重最低,仅为236 g。[结论]综合各品种产量、生育期、抗逆性等品种特性,苏玉41可在沿江高沙土地区进一步种植推广。[Objective]To screen new spring maize varieties with high yield and resistance in high sandy areas along the river.[Method]With Jiaodianyu 1303,Jundan 20,Suyu 23,Suyu 29(CK)and other maize cultivars as the test materials,we researched their agronomic characters,yield structure and stress resistance in high sandy areas along the river.[Result]The whole growth period of tested varieties was shorter than the control.Among them,the whole growth period of Jundan 20 was the shortest,which was 118 d.The yield of Suyu 41 was the highest,which was 9363.9 kg/hm^2,followed with Jiaodianyu 1301,which was 9308 kg/hm^2.Compared with CK,Suyu 41 and Jiaodianyu 1301 enhanced by 12.22%and 11.55%.The 1000-grain weight of Chunfeng 886,Suyu 20 and Suyu 41 were 375,353 and 313 g,respectively,which were significantly higher than the control.But the 1000-grain weight of Suyu 23 was the lowest,which was only 236 g.[Conclusion]Considering the yield,growth period,resistance and other characters,Suyu 41 could be further cultivated and popularized in high sandy areas along the river.
