摘要:
为选育优质、高产的糜子新品种，对20个糯性糜子品种的7个农艺性状进行了遗传多样性研究。结果表明：参试的20份糜子品种遗传多样性比较丰富，单穗粒重的遗传多样性指数最高，为2.19，主茎节数的多样性指数最低，为1.37。基于农艺性状的聚类分析把20份种质分为5大组群，其中，第一组群的齐黍1号这份材料的产量最高；第五组群的内糜8号和雁黍11的穗粒重在所有参试材料中是最高的，属于丰产型种质，应作为糜子杂交育种的亲本加以重点利用。
Abstract:
In order to breed the new varieties of waxy broomcorn millet with high quality and high yield,the genetic diversity of sevev agronomic traits was assessed in twenty waxy broomcorn millet varieties.The results showed that the diversity index of grain weight per ear was the highest with the number of 2.19 while that of number of node was the lowest by 1.37.Based on the agronomic data,20 broomcorn millet accessions were clustered into 5 groups.The character of yield of Qishu 1 from the first group and spike weight of Neimi 8 and Yanshu 11 from the fifth group were the highest in all germplasm which should be used as focus accession in crossbreeding of broomcorn millet.
