| Abstract: | Studies with 9 maize inbred lines from the tropical subtropical zones and 5 temperate lines representing the main heterotic groups of China by two methods of SSR molecular markers and field experiment according to NC-Ⅱgenetic designs,showed that the yield SCA of the combinations of Ye 478×CML310,Mo17×CML10,Huangzao 4×CML107,Lu9×CML310, Zi330×CML312 were higher than those of other combinations.The maize inbred lines tested were divided into 6 heterotic groups according to the results of SSR molecular marker. CML10 and CML265 were involved in the first group,CML127, CML96, CML295, Mo17 in the second group, CML323,Huangzao 4 in the third group, CML310,CML312,Z 330, D340 in the fourth group, CML107 in the fifth group,Ye 478 in the sixth group.The results of the classification on the heterotic groups based on SSR molecular markers accorded essentially with the results based on the yield combining ability and that based on the family analysis. |
