| 摘 要： | 试验以不同类型的小麦杂交组合后代为材料，探讨在异质竞争条件下植株形态性状与产量的关系，并以此对小麦高产群体株型结构选择指标进行分析。结果表明：植株各节间在异质竞争条件下对产量性状的影响作用不同。株高构成指数（１）的高低可以较好地反映群体产量的高低。Ⅰ值较高的组合有利选出高产类型。

| Abstract: | Different types of wheat cross-combination offsprings chosen as materials,the relationship between plant morphologic characters and yield was studied under the condition ddifferent competition in different combinations.Meanwhile,the criterion used for choosingwheat high-yield population plant structure was analysed.Results showed that knot lengthof plant had different effects on yield characters under the condition of different competitionThe value of plant height form index may well reflect the population yield.Higher index combinations may be favorable to the selection of high-yield types. |

| Keywords: | different competition wheat plant height form index population yield |
