A selection program using reciprocal recurrent selection procedures in maize (Zea mays L.) was developed. Intra-and interpopulation selection procedures were used for two maize populations BS10 and RSSSC. Intrapopulation selection procedures included phenotypic mass selection for multiple leaf and multiple stalk-rot disease resistance and S1 family selection for grain yield in a high-yield environment. Interpopulation improvement involved selection of testcrosses of S1 family×inbred tester in a high-yield environment. Evaluations of populations per Se, population crosses and populations×testers for response to three cycles of selection for grain yield were conducted at four environments. 在高產環境下，利用BS10及RSSSC兩個玉米族羣進行兼顧族羣內及族羣間改良之相互輸迴選拔。族羣內之改良包括多種葉斑病、莖腐病等抗病性的外表型混合選種及S1系統在高產環境下之產量評估。族羣間之改良則包括測交系統在高產環境下之產量試驗及選拔。三個輸迴之選種效應評估，分別利用族羣、族羣雜種及族韋測交種等，於四個不同環境下進行產量試驗；並利用族羣及族羣雜種於病圃檢定其對葉斑病及莖腐病之抵抗性。
