摘要
近年来粟锈病发生严重,影响粟的产量和质量。1983—1985年对春谷839份和夏谷1021份,进行田间成株期及部分品种温室苗期抗锈性鉴定。结果是,春谷未出现高抗类型,中抗的仅有两个品种,占鉴定品种数0.24%;夏谷高抗锈病的品种18个,占鉴定品种数1.76%;中度抗病(2型)有33个品种,占鉴定品种数3.23%;并发现部分抗性品种36个,占鉴定品种数3.53%。
From 1983 to 1985,1021 samples of summer millet and 830 samples of
spring millet were examined in the field to determine their mature plant
resistance to rust,and 104 samples of summer millet in a green house in
winter for seedling resistance.
Of all the varieties examined,both spring and summer millets,none was
found immune to rust.However,18 summer millet varieties were identified
as highly resistant,and 33 as moderately resiatant.In the spring millet
group,only two varieties were rated as moderately resistant.In addition,
36 varieties were identified as partial resistant.These were of the type with
high incidence rate but mild disease symptom.
The result of seedling resistance test did not agree fully with that of
adult plant test,but there appeared to be a significantly positive correlation
between the two.
