摘要
对K326×中烟90组合的DH群体的主要农艺性状进行聚类分析,初步形成了其中119份材料的系统聚类,结果表明在欧氏距离3.13处可划分为5个类群。第一类群6份材料,第二类群43份材料,第三类群38份材料,第四和第五类群各16份材料。综合看第一类群表现不佳,第二类群经济性状表现良好,第三类群表现居中,第四类群表现最优,第五类群产量最高。
For DH lines in population K326 × Zhongyan 90,preliminary systemic clustering analysis was conducted based on main agronomic traits of 119 materials.The results indicated that it could divided to six classes at the Euclidean distance of 3.13.The first class included 6 materials,the second class included 43 materials,the third class included 38 materials,the fourth and the fifth classes included theirs 16 mate-rials .The poor performance was the first class,the second class had good economic traits,the center com-prehensive was the third class,the best comprehensive performance was the fourth class,the highest yield was the fifth class.
