为探索常规棉产量与主要性状的相互关系，以2013年湖北省棉花区域试验19个棉花品种为材料，运用灰色系统理论对影响常规棉产量的12个主要性状进行灰色关联分析。结果表明，主要性状与常规棉产量的关联度大小依次为：籽指（r＝0．491）＞铃期病指（r＝0．430）＞衣指（r＝0．404）＞单株铃数（r＝0．396）＞始果枝着生节位（r＝0．394）＞果枝数（r＝0．390）＞衣分（r＝0．388）＞霜前花率（r＝0．382）＞生育期（r＝0．377）＞单铃重（r＝0．367）＞株高（r＝0．345）。说明在常规棉的选育和高产栽培时，要选择籽指较高、抗病性强的品种，同时注重结铃性和早熟性。

In order to clear relationship between yield and main traits of the conventional cotton . the autor took 1 9 cotton vari-eties from regional test as materials in Hubei province in 201 3,carrying on the grey relation analysis of 1 3 main characters adopted the grey system theory. Results showed that,the correlation of main characters and yield was as followed:seed index (r=0 . 491 )>disease index of bell stage (r =0 . 430)>lint index (r=0 . 404)>boll number per plant (r=0 . 396)>beginning fruit node (r=0 . 394)>branch number (r =0 . 390)>lint (r =0 . 388)>flowering rate before frost (r=0 . 382)>growth period (r=0 . 377)>single boll weight>plant height (r=0 . 345) . In breeding and high-yielding culti-vation of conventional cotton,choosing the higher seed index and stronger disease resistance of variety ,at the same time,pay-ing attention to boll setting and precocity .
