摘要：

对北方冬麦区1983～1988年高肥区域试验的80个参试品种的产量性状进行相关与通径分析。结果表明,北部冬麦区和黄淮麦区北片参试品种的增产因素主要是穗粒重,其次是亩穗数;黄淮南片参试品种的穗粒重与亩穗数对产量的贡献几乎相等,亩穗数稍大于穗粒重。鉴于直线相关是有一定范围的,结合各片的生态条件及育种实践,认为培育400公

Abstract:

Correlation study and path analysis were made using data of the yield traits of 80varieties from the high fertility level regional tests of the North China Winter WheatRegions from 1983 to 1988. The results indicated that the most important factor forthe increase of grain yield in the North Winter W
