<![CDATA[The genetics of resistance to Philippine downy mildew in maize (Zea mays L.) caused by Peronosclerospora philippinensis was studied in progeny derived from crosses between the resistant inbred P 345 and susceptible inbred Pi 17 and Pi 23. Plant generations used in this study were the PS (susceptible lines Pi 17 and Pi 23); PR (P 345); extensively F1, F2; F3; BS and BR. Plants at three leaf stages were artificially inoculated and evaluated for components of resistance, namely: disease incidence, disease severity, onset of systemic symptom, area under disease progress curve, and rate of downy mildew development. Analysis of generation means indicate that additive- dominance with epistasis gene effect play important role in all components of resistance to Philippines downy mildew.]]>
