| 摘 要： | 目前吉林省推广的玉米骨干自交系吉63果穗上发生的穗腐症状是由Hel-minthosporium carbonum Ullstrup侵染引起的圆斑病。从病斑形态和培养性状与小斑病菌迥然不同。经温室苗期和田间成株期人工接种证明,圆斑病菌除为害吉63和少数自交系外,不侵染T型、M型等不育系及多数正常系玉米的果穗。从果穗抽出到灌浆期是圆斑病菌侵染发病的关键时期。病菌主要在病株残体里以菌丝体越冬,已腐烂的病组织则丧失生活力。六年共鉴定655份自交系、品种及杂交种,有184份材料的果穗感病,以吉63及其选系后代发病最重。经测定吉63感染圆斑病是由隐性感病基因所控制。

| Abstract: | Ji-63 is an important inbred line of corn in Jilin province,but there occured an eardecay disease to cause heavy loss.The causing organism has been identified to be Helminthosporium carbonum Ullstrup which infects the ears and leaves on corn.The morphology and culture characters of the pathogen are different from those of H.maydis. Inoculation tests made at seeding-stage in greenhouse and adult stage in field.It revealed that H.carbonum can only infect the ears of thenormal-cytoplasmic type Ji-63 and few other lines,but not the T-and M-cytoplasmic type sterile and other normal lines. The prevalent period of infection is from heading to milk-stage.The pathogen is mainly overwintered in the residual tissues by mycelium. Resistance of the 655 inbred lines and hybrids has been estimatedin the fields in 1976-1981.Ji-63 and its selective lines were susceptible. |
