| 摘 要： | 对1997~1998年度参加全国旱地区试的16个冬小麦品种产量三因素与产量进行相关和通径分析,结果表明三因素都与产量具有正相关关系,其相关系数大小顺序为：穗粒数＞千粒重＞公顷穗数;直接通径系数大小顺序为：穗粒数＞公顷穗数＞千粒重。因此在选育旱地小麦品种时应注重协调好产量三因素之间的关系,在取得一定的群体穗数的基础上,以千粒重和穗粒数为重点性状。

| Abstract: | This article analyzed 16 winter wheat varieties which tested in the state dry-land variety examination in 1997 - 1998. The result shows that there is always positive correlation between yield and yield components ,its sequence is: grain number>1000-grain weight>spike number. The sequence of direct path coefficient is :grain number>spike number > 1000-grain weight. Then , during breeding of dry-land wheat , we should coordinate the relationship ,and base on certain population spike , emphasize the characters of grain number and 1000-grain weight. |
