To select maize germplasm with adaptive potential to waterlogging, stress treatment was applied to maize at knee-high stage by continuous submergence for 3-6 days with ponding depth of 5 cm of water. Yellowand white waterlogging tolerant materials were identified and subsequently handled by modified SI recurrent selection with testing in both stress and non-stressed conditions. Work to establish heterotic grouping among the tolerant materials identified is underway by top crossing with two yellow inbreds, namely; Tarun 08313-3-2 and D831039-2-1-1 and also two white inbreds; CM400 and CM600. The results of waterlogging work accomplished to date are discussed in relation to genetic variation for waterlogging, effects of waterlogging stress in maize, and identification of some traits related to waterlogging stress tolerance.Collection: CIMMYT Staff Publications Collection
