The variation of root growth ability in seedling stage among rice varieties and its heterosis and genetics were studied with 8 rice varieties and 4 X 4 incomplete dialle crosses. There were significant difference of numbers of root, root length, root width and root growth ability among varieties. The heterosis was great and variation among crosses was great. They were mainly controlled by non-additive heredity
