摘要
用简单相关和逐步回归的分析方法，从不同的角度对缘毛雀麦种子生产的数量性状与单穗籽粒产量的关系进行分析。结果表明：缘毛雀麦的整穗重、穗轴节数、小穗数、小花数、籽粒数等各性状间均存在着极显著的正相关。而穗长、小穗数、整穗重、籽粒数性状组合控制了籽粒产量的９９ ．３７％ ，其中，整穗重和籽粒数对单穗籽粒产量有正的效应，而穗长，小穗数的效应均为较小的负值，这表明穗重、籽粒数是影响籽粒产量的重要因素。
The techniques of simple correlation analysis and gradual regression were used in this paper to analyse the relationship between quantitative characters related to seed production of Bromus ciliatus and its seed yield in a single head.The results showed that there were significant positive correiations among some characters like whole head weight,node number of spike stalk,spikelet number,floret numbr and seed number of Bromus ciliatus. 99.37%of the seed yield were controlled by the character combination of spike length spikelet number,whole spike weight and seed number,in which whole spike weight and seed number produced positive effect on seed yield of single spike,whereas the spike length and spikelet number produced negative effect.This illustrated that spike weight and seed number were the important factors affecting the seed yield of Bromus ciliatus.
