| 摘 要： | １９９３，１９９５，１９９６三年在长春种植６个冬小麦品种，观察和分析了冬小麦的基本苗数、茎数和穗数的表现，并对越冬率和产量构成因素进行了相关分析，结果表明，越冬率和穗数、穗数与产量均呈极显著的正相关，其它性状间相关未达到显著水平。通径分析结果表明，对产量的直接影响力穗数最大，越冬率最小。越冬率经穗数对产量的间接影响力为最大。

| Abstract: | Varieties of winter wheat were planted in
Changchun in 1993, 1995 and 1996. The number of seedling, the number of stem and number of
spike were observed. Correlation analysis between rate of overwintering and yield componenet
were made. The result showed that coefficients of correlation of rate of overwintering with yield
and spike number with yield were possitively significant at the 1% level. however, the
coefficients of correlation among others characters did not reach significant level. Path analysis
showed that the direct effect of spike number on yield was the largest and the direct effect of
rate of overwintering was the least. The indirect effect of rate of overwintering on yield through
spike number was the largest. |
