Prediction of combining ability in some maize (Zea mays L.) inbred lines using top-cross method under different environments


Abstract in English

This research was carried out to evaluate the combining ability of twentyfive inbred lines of yellow maize and estimate the phenotypic correlation and path analysis of twenty-five top crosses were formed during 2009 growing season at Dir Ala, Dead Sea. Jordan. Their plants were evaluated in Syria during 2009 growing season in three locations (Al Raka, Aleppo and Dir Al- Zor).
