| 摘 要： | 利用灰色系统理论，对１９９８￣１９９９年河南省超高产小麦良种区试结果进行了分析。结果表明，主要性状对产量的关联度顺序，冬水组为：株高＞千粒重＞最高蘖数＞穗数／６６７ｍ＾２＞成穗率＞穗粒数；春水组为：株高＞千粒重＞穗数／６６７ｍ＾２＞最高蘖数＞穗粒数＞成穗率。参试品种（系）中，冬水组以９６中６７２表现最好，其次为临９５３与周麦１３；春水组以济麦１号表现最好，其次为偃展２号与内乡１８８，并初步探讨了灰

| Abstract: | By means of grey system theory, the 1998~1999 results of Henan province regional test for super high yield wheat varieties were analyzed. The results showed that the order of relational grades of important characters to yield in winter water group was plant height > 1000 grain weight > No. of maximal tillers > No. of panicles/667m 2 > effective panicle rate > grains per panicle; the order in spring water group was: plant height > 1000 grain weight > No. of panicles/667m 2 > No. of maximal tillers > grains per panicle > effective panicle rate. In the winter water group, 96 zhong 672 was the best one, next was Lin 953 and Zhoumai 13. In the spring water group, Jimai 1 is the best one, next is Yanzhan 2 and Neixiang 188. The application of grey system theory on super high yield wheat breeding was discussed preliminarily. |
