On the basis of percentage of overall died plants and variance analysis,judgement on 18 different resistant linseed breeds and filial generations grown in natural wilt nursery indicated that the resistance to wilt was classified into 4 types:high resistance (below 9%),middle resistance (19%~37%),middle susceptibility (46%~65%) and high susceptibility (80%~87%).Every type was divided into 3 grades in practice.The result showed classification of different resistant lines was and reliable according to percentage of overall wilt plants.Marking 8 different resistant linseed lines by peroxidase isozymes indicated the more susceptible the lines were,the more number and active the enzyme lanes were.

对胡麻 18个抗病性不同的材料进行田间自然病圃发病率调查 ,以总枯死率为依据 ,经方差分析划分为 4种抗性类型。即总枯死率小于 9%为高抗型 (HR) ,19%~ 37%为中抗型 (MR) ,46 %~ 6 5 %为中感型 (MS) ,80 %~87%为高感型 (HS) ;应用中各类型又划分为 3个等级 ;表明以总枯死率鉴定抗病类型准确、可靠 ;对抗性不同的 8个材料进行过氧化物同工酶标记鉴定 ;表明随感病性增加 ,酶带数目增多 ,颜色加深。

The resistance and heredity relationship of ten varieties of Vitis vinifera,a hybrid of V.vinifera and V.amurensis and 493 plants offspring to Uncinula necator and Plasmopara viti-cola were studied with inoculation evaluation in the field and artificial inoculation evaluation on leaf discs in the laboratory.In addition,heredity trend of self progenies to U.necator and P.viticola were also researched.The results showed that the resistance distribution of experimented varieties to P.viticola was very significantly...

The resistance and heredity relationship of ten varieties of Vitis vinifera,a hybrid of V.vinifera and V.amurensis and 493 plants offspring to Uncinula necator and Plasmopara viti-cola were studied with inoculation evaluation in the field and artificial inoculation evaluation on leaf discs in the laboratory.In addition,heredity trend of self progenies to U.necator and P.viticola were also researched.The results showed that the resistance distribution of experimented varieties to P.viticola was very significantly correlated with that to U.necator.The heredity of the self-bred progenies to U.necator and P.viticola was accompanied with each other.And this accompanied heredity phenomenon was caused by the manifold effects of the disease-resistance genes in vine.Although more than 90% self-bred progenies were middle susceptibility and high susceptibility,less than 10% self-bred progenies were high resistance types.This provided basis for using V.vinifera to breed top quality and high disease resistance grape varieties.

采用田间自然鉴定、田间接种鉴定及室内离体叶国片接种鉴定三种方法,研究了10个欧亚种葡萄品种(系)、一个欧山杂种及其493株自交后代幼苗对葡萄霜霉病及白粉病的抗性及遗传关系,同时对其自交后代抗白粉病和霜霉病的遗传趋势进行了分析。结果表明,供试品种(系)及其自交后代对霜霉病与白粉病的抗性存在极显著相关,自交后代对两病表现伴随遗传现象,初步推断这可能是由葡萄抗病基因的多效性引起。在欧亚种葡萄品种自交后代群体中,虽然90%以上都是感病性中等或高的类型,但仍能够得到一定比例(10%以下)抗病性强的类型,这为利用欧亚种葡萄品种进行自交或品种间杂交选育优质抗病新品种提供了依据。

Analysis with 20 corn varieties show that the different corn varieties existed the certainly difference of disease resistance to the southern leaf blight of corn and corn curvalaria leaf spot .

Analysis with 20 corn varieties show that the different corn varieties existed the certainly difference of disease resistance to the southern leaf blight of corn and corn curvalaria leaf spot . Among them, the southern leaf blight of corn occurred in the middle, seriouslness and 20 corn species were divided into three kinds of type of disease resistance of high susceptibility, middle susceptibility and middle resistance. The corn curvalaria leaf spot occurred lightly and 20 corn species were divided into two kinds of type of disease resistance of middle susceptibility and middle resistance. Analysis on the occurring factors that effected the corn curvalaria leaf spot and corn curvalaria leaf spot showed that the seriousness of the disease was effected by themeteorological factors( temperature,humid,rainfall and light hours),sowing time and planting density besides the disease resistance of variety.

试验就2 0个玉米品种分别对小斑病和弯孢霉叶斑病的抗性进行了研究。结果表明,不同玉米品种对小斑病和弯孢霉叶斑病存在着一定的抗性差异,其中,玉米小斑病的发病严重程度为中偏重发生,将2 0个玉米品种划分为高感、中感和中抗3种抗病类型。弯孢霉叶斑病为轻发生,将2 0个玉米品种划分为中感和中抗2种抗病类型。分析了影响小斑病和弯孢霉叶斑病发生的因素,表明其发病程度除受品种抗病性的影响外,还受到气象因素(如温度、湿度、降雨量和光照时数)、播期和种植密度等因素的影响。
