Results showed that average lint yield of F1 was 1296.30 kg/hm^2, which was an increase by 214.38 kg/hm^2, compared with CK and its average competitive dominancy was 19.81%; Average lint yield of F2 was 1168.65 kg/hm^2, an increase by 86.73 kg/hm^2, compared with CK and its average competitive domain was 8.01%; Average lint yield of F3 was 1117.65 kg/hm^2, an increase by 35.73 kg/hm^2 compared with CK and its average competitive dominancy was 3.30%. F3 had the highest competitive dominancy, then F2 and F3 whose decreasing ratio is consistent with their competitive dominance, and their average yield decreasing ratios were 12.59% and 17.62%, respectively.

结果表明，F1平均皮棉总产量为1296.30 kg/hm^2，比对照泗棉3号增产214.38 kg/hm^2，平均竞争优势为19.81%；F2平均皮棉产量为1168.65 kg/hm^2，比对照增产86.73 kg/hm^2，平均竞争优势为8.01%；F3平均皮棉产量为1117.65 kg/hm^2，比对照增产35.73 kg/hm^2，平均竞争优势为3.30%。F1竞争优势最大，其次为F2，F3，F2，F3的衰退率与竞争优势一致，其平均优势衰退率分别下降了12.59%和17.62%。

In recent years,medial average has still not been introduced in Sports statistics,which is used as a textbook in institutes of P.E. On the basis of analyzing the nature of medial average ,the author proposes that medial average is commonly got using average rates in sports researches because of its features and laws. Since medial average is gained by reciprocal of its observation value,a quick method of arithmetical average might be medial average equals to...

对近年来未把调和均数列入体育院校《体育统计学》通用教材提出了不同的看法，认为根据体育运动的特点与规律，在体育科研中，利用速率计算均值的情况较多，由于调和均数是应用其变数值的倒数来计算算术平均数，所以在加权正确的情况下，调和均数与算术均数计算结果相等，是算术均数的简捷计算方法，应该向学生介绍调和均数并列入教材。

The average percentage of polymorphic bands are 72.06% for ISSR and 66.67% for RAPD respectively. The genetic diversity of ginkgo revealed by ISSR (the average effective number of alleles is 1.8780, the average Nei"s gene diversity is 0.4652, and the average Shannon"s information index is 0.6574) are all higher than those by RAPD (the average effective number of alleles is 1.7842, the average Nei"s gene diversity is 0.4317, and the average Shannon"s information index is 0.6211), while the standard errors of the parameters estimated by ISSR were lower. Therefore, ISSR molecular markers are more suited than RAPD molecular markers when testing the genetic diversity of ginkgo populations and determining the genetic relationship of among populations or among individuals which are much similar hereditarily.

本文应用RAPD和ISSR两种分子标记技术，选取中国5个可能的野生银杏居群共计75个样品，对其遗传多样性进行了研究，得出以下结论：(1)用筛选出的12个RAPD引物和10个ISSR引物进行PCR扩增，分别扩增出65条和68条重复性高、清晰的条带，多态性位点百分率分别66.67%和72.06%，ISSR揭示的银杏遗传多样性(平均有效等位基因数目为1.8780，平均基因多样度为0.4652，平均信息指数为0.6574)高于RAPD所得到的结果(平均有效等位基因数目为1.7842，平均基因多样度为0.4317，平均信息指数为0.6211)，其所估算参数的标准差要低于RAPD所估算出的值，因此，在研究亲缘关系非常近的银杏物种的遗传多样性并试图确定居群间或个体间的遗传关系时，ISSR分子标记技术比RAPD分子标记技术更为合适。
