摘 要 ：用4个软质胚乳和4个硬质（或半硬质）胚乳的高赖氨酸玉米自交系，进行8×8完全双列杂交试验，分析了后代籽粒品质性状的遗传表现和配合力。软质胚乳亲本和硬质胚乳亲本杂交时，当代F1籽粒的胚乳硬质度表现出显著的正反交差异，以硬质亲本作母本时F1籽粒硬质度较高，但F2籽粒的硬质度无显著的正反交差异。硬×硬类型杂交后代的

Abstract:Eight opaque-2 inbred lines of maize, four with soft endosperm and four with hard or semihard endosperm, were tested in diallel crosses including 28 reciprocals. There was evidently maternal effect on the endosperm hardness of F1 kernels but no such effect in the F2 kernels. The F1 kernels were usua
