玉米C群不同亚群雄性不育细胞质对玉米小斑病菌C小种侵染的反应
REACTION OF DIFFERENT MALE-STERILE CYTOPLASM SUBGROUPS OF THE C GROUP MAIZE TO THE INFECTION OF BIPOLARIS MAYDIS RACE C
【摘要】 通过4年的田间与室内试验,证实玉米C群中的(CI亚群(cms-C)对玉米小斑病菌C小种专化感病,而CⅡ亚群(cms-RB)和CⅢ亚群(cms-ES)则不严重感病。这表明(CⅡ和CⅢ两个亚群可以在生产上应用。
【Abstract】 Through four-year experiments in fields and laboratory, we found that subgroup C I (cms-C) of the C group maize (Zea mays L.) was especially susceptible to Bipolaris maydis race C; while subgroup CⅡ (cms-RB) and CⅢ (cms-ES) were not seriously infected. This shows that subgroup CⅡ and CⅢ can be used in production.
