【摘要】 本文报道了近几年国内育种单位育成的36个不育系,对小斑病菌 T 小种的抗性鉴定结果。通过温室苗期和田间穗期的接种反应表明,21个感病的不育系,其细胞质属 T 型或与之相似的类型。在15个抗病的不育系中,已知细胞质名称的有 C 型和双26A (称为“双”型)、“唐徐”型。后两者均属 S 组不育胞质类型。更多还原

【Abstract】 Studies were carried out both in greenhouse and in the field,by inoculating 77-11(Race T)of Cochliobolus heterostrophus Drechsler to seedling and ear of male-sterile lines of corn with different cytoplasms.It was found that 15 male-sterile lines were resistant and 21 were sus-ceptible.The resistant sources were cms-C,“Shuang 26A”and“Tangxu”(i.e.cms-S),while cms-T and its near relative were susceptible.更多还原
