| 摘 要： | 1992~1995年在田间接种条件下对大豆灰斑病叶部发病情况进行系统调查,获得86组感病品种(合丰22)和66组抗病品种(合丰25)普遍率与严重度间对应关系数据,在计算机上分析了两者的关系(I-S关系)。结果表明,感病品种和抗病品种叶部病害的I-S关系均可用直线方程描述,其直线回归方程分别为:#br#SS感=-2.8029+0.5252IS±6.4364(SS、IS-感病品种严重度和普遍率)#br#SR抗=-0.3843+0.6334IR±3.7679(SR、IR-抗病品种严重度和普遍率)#br#协方差分析结果表明,大豆品种的抗病性对大豆灰斑病叶部病害的I-S关系有一定影响。

| Abstract: | The information of
incidence and disease index of soybean frogeye leaf spot(Cercospora sojina Hara.)were
obtained through inoculation experiments conducted in the field from 1992 to 1995.The
relationship between disease incidence and severity(IS)of soybean frogeye leaf spot was
analyzed.Results showed that the IS relationship of soybean frogeye leaf spot on leaf could be
expressed individually by following linear regression equations.The equation of susceptible
variety is
SS=-28029 05252IS64364(0SS546%,0IS871%,R=09139**,R2=08352,S.E.=49779,n=86).The
equation of resistant variety is
SR=-03843 06334IR37679(0SR401%,0IR687%,R=09700**,R2=09410,S.E.=29096,n=66).The IS
relationship of soybean frogeye leaf spot was affected by the resistance of soybean varieties to
the pathogen. |
