title: [Genetic potentiality of utilizing Yugoslavia maize inbred lines to improve Chinese elite hybrids].
abstract: In this study, 107 crosses were made using 9 Yugoslavia maize inbred line as female and 13 parent lines of 8 Chinese elite hybrids, belonging to different heterotic groups, as male. Though Dudley's method the genetic potentiality of 9 Yugoslavia maize inbred lines were analyzed for the improvement in the yield of 8 Chinese elite hybrids and main ear -kernel characters, and for their proper applications. The results showed that the introduced Yugoslavia inbreds had broad genetic basis and high breeding value in indirect utilization. Almost all Yugoslavia inbreds, including 9801, 9802, 9803, 9805, 9807, 9808, and 9809, could improve the yield of Yuyu15, GailiangYuyu20, Yuyu22, Yuyu23, Yuyu24, Shendn10 and Nongda 108 through different parents and ear-kernel characters, while the real improving effects should be proved in further practical breeding.
