摘  要:
1984—1986两年间共鉴定34个小麦品种(系)对小麦赤霉病的抗性,结果表明:(1)供试各品种(系)间抗性有明显差异,但无免疫类型,抗病品种也较少,(2)综合评定结果表明:郑引一号、7023、花培28抗病性较强,占8.8%;偃师九号,宛7107等14个品种(系)抗性中等,占41.2%;百泉3039、百农3217、宝丰7228等17个品种(系)属于感病类型,占50.0%,(3)在研究品种抗性与生物学特性的关系时发现:品种抗感性与籽粒颜色、株高、花药残留率、开花历期有一定的相关性,而与小穗密度无关。

摘  要:
During 1984—1936,34 wheat varieties(strains)were studies for their resi- stance to the head blight.The wheat varieties(strains)were inoculated with se- ed-born of wheat and cornstalks-born in the test field.From the experiments,we have the following results.There are a great difference among the resistance of the 34 wheat varieties(strains)for the head blight,but there are not any imm- une.The susceptible rate of the three wheat varieties(strains)i.e.Zhengyin 1, 7023 etc.were 8.80%;the susceptibility of fourteen wheat varieties(strains)i.e Yansi 9,7107,etc.was in the middle accounting for 41.20%,the other wheat va- rieties(strains)i.e.Bainong 3217,Baiquan 3039 were of 50% of susceptibi- lity,meanwhile it was found that the resistance or susceptibility of varieties(st- rains)was related to the colour of seed,the plant height,coefficient of survi- vor of the pollen sac,and the florescence time etc.
