摘　　要：四-287是以四-444×255为基础材料,经北方和海南连续自交6代选育而成的优良玉米自交系,具有早熟、配合力高、抗病性好、结实性好、适应性广等优点。与四-444相比,四-287在熟期、抗病、抗逆、农艺性状上实现了改良创新,是2000年以来东北区塘四平头种质改良的成功范例。以其作为亲本及衍生系选育出吉单27等玉米新品种并大面积推广应用,推动了塘四平头种质在春玉米早熟地区的规模化应用。Maize inbred Si-287 was bred from two inbred lines Si-444×255 by six generations of continuous inbreeding in the North and Hainan province of China.It had the advantages of early maturity,high combining abili⁃ty,great disease resistance,good firmness,wide adaptability,and so on.Compared with the Si-444,it had achieved improvement and innovation in maturity,disease resistance,stress resistance and agronomic traits,which was a suc⁃cessful example of the germplasm improvement of“Tangsipingtou”in Northeast China since 2000.With its use as a parent and derivative system,it had selected new maize varieties such as Jidan 27 promoted and applied in large ar⁃eas,which promoted the large-scale application of the“Tangsipingtou”germplasm in early maturity areas of spring maize.
