Index screening and comprehensive evaluation of phenotypic traits of low nitrogen tolerance using BILs population derived from Dongxiang wild rice( Oryza rufipogon Griff.)
To identify the low nitrogen tolerance of Dongxiang wild rice( DXWR) and its progenies,ten phenotypic traits including plant height( PH),heading day( HD),panicle length( PL),number of effective tillers per plant( NETP),number of filled grains per panicle( NFGP),number of grains per panicle( NGP),grain density( GD),spikelet fertility( SF),1000-grain mass( TGM) and grain yield per plant( GYP) were studied under normal and low nitrogen treatments,using backcross inbred lines( BILs) of Xieqingzao B / / DXWR / X...
