文摘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\’a1\’c14 incomPlete dialle crosses. There were sighficant 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.
