玉米小斑病生理小种的侵染特征与玉米雄性不育胞质的利用

详细叙述了玉米小斑病Ｔ、Ｃ小种的侵染特征，并在对二者分析比较的基础上，提出了玉米雄性不育胞质的利用途径：（１）育成异型胞质杂交种；（２）在同一地区内推广分别属于不同胞质类型的同一杂交种或不同杂交组合；（３）不育胞质与正常胞质杂交种掺合使用；（４）无论哪种方法，都应以选育抗小斑病Ｏ小种或其它小种的核背景为前提

The Infective Character of the Maize Bipolaris Maydis Races and the Use of Corn Male-sterile Cytoplasm

Based on the detail analysis and comparison of the infective characteres of Bipolaris Maydis Race T & C the using methods of the corn male-sterile cytoplasms were suggested:(1)selecting corn hybrid varieties with different male-sterile cytoplasms;(2)spreading the same or different corn hybrid varieties with different male-sterile cytoplasms in same destrict;(3)using the same corn hybrid varieties with the male-sterile or normal cytoplasm mixed;(4)selecting the corn nucleus that must be resistant to Bipolaris Maydis Race O or otheres in either of the methods above
