摘要
用普通玉米自交系和O2玉米自交系进行双列杂交,对普通玉米×O2玉米(普×O2)、普通玉米×普通玉米(普×普)和O2玉米×O2玉米(O2×O2)三种类型杂交组合F1的子粒赖氨酸含量、产量、赖氨酸产量、容重、收获时子粒含水量进行了比较分析。结果表明:普×O2组合的赖氨酸含量介于普×普和O2×O2之间,但变化幅度较大;产量和粒重最高,容重和收获时子粒含水量介于两者之间偏近于普×普,赖氨酸产量和O2×O2接近。认为以普通玉米与O2玉米自交系组配杂交种是一种值得探讨的高赖氨酸玉米选育方法。
Common and opaque-2(O2) inbred lines of maize were tested in a diallel design. The lysine content, yield, lysine yield, kernel weight, kernel density and water content of kernel in harvesting were analyzed. The crosses between common and O2 inbred lines were better than O2 hybrids in yield, kernel weight kernel density and water content in harvesting. The lysine content of common×O2 hybrids were lower than that of O2 hybrids but their lysine yields were very close. The results of the expriment indicated that: it was a way to breed maize hybrid with high lysine content by crossing common maize inbred lines with O2 inbred lines.
