Evaluation of 100 Oat Germplasms for Stem Rust Resistance
摘要
Abstract
Stem rust resistance of 100 oat germplasms was evaluated from 2011 to 2012 by inocula-ting the mixture of oat stem rust isolates at two test sites during booting stage .The results showed that 5 hulled oats ,such as Yuanliyoumai and so on ,and 13 naked oats ,such as Erqiuyou-mai and so on ,were immune ,resistant or slow rust at least at one test site .One hulled oat ,Pinyan 1 ,and 10 naked oats ,such as 64 Yanmai and so on ,were moderately resistant or moderately sus-ceptible with severity from 40% to 60% at least at one test site .Most of the germplasms men-tioned above were more resistant at test site 1 with low temperature ,which was deduced to be in accord with the fact that most of oat stem rust resistance genes were low-temperature resistant . The rest cultivars or lines were susceptible or high susceptible .Hence ,the five hulled oats and 13 naked oats could be used as resistant resource for stem rust .关键词
