Abstract
本試驗以七個玉米自交系親本（四個硬粒種及三個馬齒種）及其四十二個全互交組合於1992年秋作進行田間試驗，莖葉性狀及青割產量之資料利用Griffing方法I作全互交分析。變方分析結果顯示，十項性狀在參試品系間均呈極顯著。十項性狀中只有吐絲期及第一穗以下葉片數兩性狀具有正反交效應。Seven inbred lines (four flint types and three dent types) and their forty-two single cross hybrids were evaluated for stem and leaf traits and forage yield in field studies conducted in fall of 1992. The analysis of variance for these traits indicated that the mean squares for genotypes were all significant. Results analyzed by Griffing's Method I indicated that estimates of GCA (except for stalk diameter) and SCA (except for leaf number above first ear) were all significant.
