| 520 | _aInsect pests are one of the main constraints to the development and farming of maize in the Caribbean. INRA CIRAD breeding efforts for well adapted maize populations with effective levels of resistance should contribute to the improvement of yield and yield stability. Screening of various insect resistant improved materials for resistance to fall armyworm, Spodoptera frugiperda (J.E. Smith) and for other characters with agronomical interest was undertaken. Multiple resistance has been observed in introduced (MIRT, TZBR) and local (PopG, Spectral) populations. The results show the high level of resistance of MpSWCB4 and ANTIGUA Gpo2, but also their low productivity. Advanced cycles, obtained through a recurrent S1 selection scheme, of a local improved population (PopG) show an intermediate level of resistance similar to FAWCC's, but are associated with high adaptability. A study of the variability within these populations and transfer of resistance to high yielding populations was initiated. The interest of this variability and its utilization in selection are discussed. | ||
