摘要: The quest for precise and rapid phenotyping of germplasm is increasing the interest breeders physiologists in application remote sensing techniques maize breeding. Twenty-four drought-tolerant inbred lines were crossed using a modified North Carolina II mating scheme to generate 96 single-cross hybrids. parents hybrids evaluated under full irrigation drought stress conditions dry seasons 2010 2011 at Ikenne, southwest Nigeria. Normalized difference vegetation index (NDVI) was recorded 3- 8-leaf growth stages. Hybrids differed significantly NDVI. Both general (GCA) specific (SCA) combining ability effects significant NDVI measured stage both regimes, with GCA accounting 53% total variation irrigation. additive non-additive genetic played roles inheritance females grain yield positively correlated ...
