Analysis for Correlation between Main Traits of Millet

ZHENG Xiang-yang~1, WU Jin-yun~2(1.Millet Institute,Shanxi Academy of Agricultural Sciences, Changzhi Shanxi 046011, China;2.Qinglongshanzhuang Company of Qinyuan County, Shanxi Qinyuan 046450, China)  
millet varieties-Xiagu 2, Hongtuigu, Jiugenqi, Shuanglugu, Datong 14, Huangruangu, Jingu 20, Jingu 21, Jingu 22, Jingu 27, Jingu 32, Jingu 33, Jingu 35, Yugu 9, Daligu-are used to study and analysis the correlations between the main agronomic characters of millet. The results show that the period of vegetative growth of millet, the seed weight of a ear, the area of the third leaf near the ear, the weight of a ear, the area of the second leaf near the ear have highly significant postive correlations with growth season; A ear weight, a ear degree of thickness, the area of the second leaf and the area of the third leaf near the ear have highly significant postive correlations with the seed weight of a ear; The degree of a ear thickness, the area of the second leaf near the ear, growth season, the period of vegetative growth of millet, the area of the third leaf near the ear have highly significant postive correlations with the weight of a ear. But spike length has significant negative correlation with the weight of a ear; Each biological character, except plant height, has a postive correlation with others. For millet breeding, varities with a larger area of second leaf near the ear, longer growth season, bigger seed weight of a ear, shorter and thicker ear should be used.
