| 摘 要： | 2002～2003年在新疆塔里木河中下游土地沙化,盐渍化较重,种植棉花长势不好的中、低产田退耕进行石丹4 号玉米、单东7号玉米、SC-704玉米品种比较试验,并对叶长等6个性状与单株鲜草质量进行相关和回归分析.经2 年试验,结果表明:石丹4号玉米、单7东号玉米、SC-704玉米适应性强,可以完成生育期.雌穗长、叶长2个性状与石丹4号玉米单株质量关系密切,且雌穗长>叶长,叶长、雌穗长的标准化回归系数分别为0.442和0.456.雌穗长、单株高、叶宽、节径等4个性状与SC-704玉米单株质量关系密切,且雌穗长>单株高>叶宽>节径,雌穗长、单株高的标准化回归系数分别为0.487和0.382.单株高、雌穗长2个性状与单东7号玉米单株质量关系密切,且单株高> 雌穗长,单株高、叶宽的标准化回归系数分别为0.530和0.379.

| Abstract: | An experiment on corn variety comparison among Shidan no. 4 corn, Dandong no. 7 corn SC-704 com had been done on heavily salted and sanded soil, and the analysis of correlation about leaf length and mass of single corn was done, between 2002 - 2003. The result indicate that adaptability of Shidan no. 4 com, Dandong no.7 corn and SC-704 corn was strong, and was able to complete whole grow period. Two traits had close relation with Shidan no. 4 single mass, female fringe length > leaf length. The standardization regression coefficient of leaf length and female fringe respectively was 0.442 and 0.456. Four traits had close relation with SC-704 corn single mass, female fringe length > single corn high > leaf width > section length. The standardization regression coefficient of female fringe length and single corn height respectively was 0.487 and 0.382. Two traits had close relation with Dandong no. 7 corn, single corn hight > the female fringe length, the standardization regression coefficient of height, leaf width was 0.530 and 0.379 respectivly. |
