L.  aGenetic variability and morphological modifications in flooding tolerance in maize, variety BRS-4154.h[electronic resource]  c2007  aMaize plants of the variety BRS 4154 - Saracura were evaluated in different cycles of recurrenl selection to determine genetic gains in flooding talerance, arranged in a random block design. The maize variety BRS 4154 in four selection cycles (1, 5. 9 and 15), together with the flooding-sensilive variety BR 107 and siingle cross BRS 1010 as control, were sown and evaluated. The stress caused by waterlogged soi! reduced the weight of 100 seeds and grain yield but did nol affect the number of kernel rows, ear length or prolificacy. Selection for yield resulted in higher yields.  abreeding  aFlooding  aGenetic variability  aMaize1 aCOELHO, C. H. M.1 aMAGALHAES, P. C.1 aGAMA, E. E.
