Abstract:
      The grey correlative degree analysis was used to research the relationships among fifteen planttype agronomic traits of F2:3 populations in maize. The results showed that the correlation degree values between leaf orientation value and other agronomic traits were sequenced as follows:Lf2(0.9147)> Lf1(0.9082)> Lf3 (0.906)> EH(0.8996)> L1(0.8856)> LW3(0.8855)> LW2(0.8854)> L3(0.8812)> LW1(0.881)> L2(0.8772)> PH(0.8691)> LA2(0.8468)> LA1(0.8444)> LA3(0.841). The result indicated the effects of plant-type traits on leaf orientation value in maize,to provide useful information for plant-type breeding,QTL mapping and genetic mechanism of leaf orientation value in maize.
