玉米种质资源抗南方锈病鉴定与评价
Identification and evaluation of maize germplasm resources against southern corn rust
摘要
Abstract
[Objective]Relevant information of maize germplasm resources against southern corn rust was complemented to provide references for continual resistant breeding and maize production.[Method]Qi 319 and Huangzaosi were used as high resistant control and high susceptible control,respectively.The artificial supplementary inoculation was used to evaluate resistance level of 379 maize germplasm resources to southern corn rust.[Result]Among 352 germplasm resources from International Maize and Wheat Improvement Center (CIMMYT),the numbers of inbred lines identified as HR,R,MR,S,HS were 139,104,38,40 and 31,accounting for 39.49％,29.55％,10.80％,11.36％ and 8.80％ of the total germplasm resources,respectively.Among 12 Chinese temperate maize inbred lines,two were identified as HR or R and 10 were identified as S or HS.Among 15 maize hybrids,10 were identified R or HR and five were identified as S or HS.[Conclusion]Most common maize varieties in Guangxi presented good resistance to SCR in this research.A lot of CIMMYT maize inbred lines were resistant gerplasm resources to SCR.关键词
