| 摘 要： | 采用灰色系统理论中的关联分析方法,对贵州省玉米区试“2003年黔西北特殊生态区G组”新参试的9个玉米新组合的数量性状进行综合分析评价。结果表明,在黔西北特殊生态区,玉米各数量性状对产量影响程度的顺序为:穗位高>千粒重>株高>出籽率>穗粗>穗行数>穗长>行粒数>生育期。在该生态区选育(引进)新品种,应选择千粒重大、出籽率高、植株矮和穗位低的组合,并兼顾有较多的穗行数、行粒数与适宜的生育期。

| Abstract: | Adopted the relate analytical method in the grey system theory,analysed 9 new maize breeds quantitative character.This maize breeds was joined the regional test"the special ecosystem of Northwest of Guizhou G group" in 2003.The result showed: in the special ecosystem,the sequence about each quantitative character affected the yield was : the spike height > thousand kernel weight > plant height > forming grains rate > spike thickes > the number of row per ear > spike length > the number of kernel per row > growing period.In this ecosystem,breeding or introduces a new maize hybrid,should selected the hybrids that have large TGW and forming grains rate;plant was short;the spike was low;the number of row per and the number of kernel per row is so big;the growing period was short. |
