Strategies for Selecting Early Maturing Maize Inbred Lines for Hybrid Production under Low Soil Nitrogen and Striga Infestation

Development, testing and selection of superior inbred lines is crucial for the success a hybrid program targeting Striga-infested low soil nitrogen (low-N) environments. The practical value determined by multiple traits, most which are inter-dependent. main objective this study was to identify early maturing based on traits under optimal, low-N environments development population improvement. One hundred were evaluated artificial Striga-infestation, optimal growing two years at Kwadaso Nyankpala in Ghana. exhibited high levels genetic variability grain yield other agronomic desirable Striga resistance tolerance. Under conditions, days silking (DS), ears per plot (EHARV) anthesis (DA) had direct effects (GYLD). Days plant (EPP) highest positive GYLD, while DA negative effect GYLD obtained with EASP. All measured previously identified have influence associated it could be used indirect improved contrasting Forty-eight 100 studied as tolerant forty-nine resistant.
