| 摘 要： | 采用2个与我国常用种质亲缘关系远的新优势种质群,即选用36份新种质合成了新的相互轮回选择的新优势群体(NRRSPⅠC0、NRRSPⅡC0)及常规的6个优势群,利用渗透势评价该群体,并与我国常用玉米种质类群进行比较,明确其适应环境的能力。结果表明:Tan-Hz C5抗旱性最强,Reid C2抗旱性最弱,新优势种质群NRRSPIC0和NRRSPⅡC0抗旱性趋于中间。 |
| 关 键 词： | 玉米 优势种质群 渗透势 |

| Abstract: | The cell osmotic potential of two new maize advantageous groups NRRSPⅠC0 and NRRSPⅡC0 which were far from Chinese common maize advantageous groups,and were synthesized by reciprocal recurrent selection of 36 new germplasm and 6 conventional advantages groups were evaluated.The results showed that the drought resistance of Tan-Hz C5 was the highest,that of Reid C2 was the lowest,and that of NRRSPⅠC0 and NRRSPⅡC0 was medium. |
| Keywords: | Maize Advantageous germplasm groups Osmotic potential |
