Progeny testing of maize ( <scp> <i>Zea mays</i> </scp> ) genotypes for grain yield and yield components, <i>Striga</i> resistance and <i>Fusarium oxysporum</i> f.sp. <i>strigae</i> compatibility

Maize cultivars with resistance to Striga spp. and compatible Fusarium oxysporum f.sp. strigae (FOS) are an economical, sustainable environmentally control option. This study's objective was determine the type magnitude of gene action controlling grain yield yield-related components, resistance, FOS compatibility select promising maize genotypes for integrated management approach. Ninety-nine experimental hybrids, generated by a North Carolina mating design II, were evaluated without treatment at three Striga-infested sites in western Tanzania. The general (GCA), specific combining ability (SCA) effects significant (P < .05) all assessed traits except, damage ratings eight (SDR8), 10 (SDR10) weeks after planting treatment. FOS-treated progenies had fewer emerged plants than untreated controls. Parental such as SITUKA M1, TZA4010, TZA4016, TZA4203, JL01, JL05, JL13 JL17 showed negative GCA parameters positive yield. new selected parents recommended breeding.
