【摘要】 大豆EMS诱变群体M₂的生育期、株高变异系数大于M₂,而且世代间的相关显著。主茎节数、分枝数和产量性状M₂和M₃的变异系数大致相同。M₃M—M₄各性状的相关值大于M₂—M₃。M₃株系与M₄品系间各性状的相关值高于M₃单株与M₄株系间的相关值。一些性状M₂株系内变异大于株系间变异,另些性状则相反,但M₂株系内变异小于株系间的变异。更多还原

【Abstract】 The soybean M2,induced by EMS,was higher than M3 on the part of rariation coefficient of growth period and height.The correlation value between M2 and M3 generation was significant.The variation coefficient of node number on main stem,branch number and yield component of M2 was equal to these of M3.The correlation value of various characters in M3-M4 was greater than that of M2-M3 The characters correlation value between M3 line and M4 line,was higher than between M3 individual plant and M4 line some charaters variation of M2 inter line was greater than that of M2 between line,bnt other characters variation was small,The variation of M3 inter line was smaller than that it’s between line..更多还原
