摘要
15个玉米自交系按照Griffing方法Ⅳ组配105个组合,以黄改系为主要研究对象,比较分析了不同杂交模式的产量结构。结果表明:在夏播条件下,黄改系一般配合力高,组配组合早熟、稳产、适应性好,穗粒数和百粒重同步增长。黄改系×MO17系统(即lancaster系统)和黄改系×BSSS系统都是夏播的理想模式。黄早4是优良种质,只能改良提高利用,不能抛弃;我国黄硬粒种质资源十分丰富,应加强研究利用。
By using 15 inbred lines, 105 combinations were obtained according to Griffing IV. Taking Huangzaosi and its improved lines as the main research objects, the yield structure of different hybrid models were compared and analysed. The results indicated that, in summer sewing, the HZIL had high combining ability, early ripeness, stable yield, good adaptability and a symchronous increase of grain weight per ear and 100 kernel weight. Both HZIL×MO17 system(Lancaster system)and HZIL×Bsss system were good summer sewing models.So Huangzaosi is a good germplasm,only needing to be improved but not to be abandoned.China is rich in the yellow-colorg ermplasms and thus,further study and utilization shoulk,be atrengthened.
