摘　　要：198 5～ 1997年对南斯拉夫玉米群体SYN1/9C0 进行半同胞轮回选择。 1998年在唐山对C1～C6和在贝尔格莱德对C4～C6等共计 10个轮回群体与 4个标准自交系进行半双列杂交研究。两年的试验结果表明 ,群体产量和杂交组合产量以及杂种优势、配合力和田间部分性状一般配合力均存在显著差异 ,南斯拉夫和唐山两地改良效果极具互补性。实验还表明 ,中国、南斯拉夫异地育种在提高南斯拉夫玉米群体自身产量、杂交组合产量的同时 ,能更为有效地提升群体杂种优势 ,使产量特殊配合力、一般配合力同时提高。In the period 1983?1997 Yugoslavia maize population SYN1/9C 0 was tested for improvement by the procedure half sib recurrent selection.In 1998,10 recurrent populations including 6 developed in Tangshan(China)and 3 in Belgrade(Yugoslavia)were crossed with 4 standard inbred lines in half diallel crossing mode.It was indicated by 2 year experimental results that such characteristics as population yields,hybrid combination yields as well as the combining ability,general combining ability of partial field characters were all significantly different among different recurrent populations respectively.Over and above,the improvemental effects both in China and Yugoslavia showed mutual implementation.It was also indicated by the experimental results that through the breeding in China and Yugoslavia,in addition to raising the yield and bybrid combination yields,the population hetaerists can raised more effectively simultaneously,SCA and GCA will be raised as well.
