为了鉴定原种场生产的原种质量,常需进行原种比较试验。过去,原种比较试验的方法和一般的品种对比试验完全一样,实际上是不甚合理的。这是因为原种和对照都是同一品种,差异不会很大。如果对照种子质量较好,差异就更小,如果采用一般的对比试验,常常不能分辨出处理的真实差异,甚至因为个别小区的误差较大,而影响到处理平均数差数的方
In order to identify the original species of the original production of seed quality, often need to compare the original species. In the past, the method of comparative test of original species was exactly the same as that of general varieties, which was actually not quite reasonable. This is because the original species and the control are the same species, the difference will not be great. If the control seed quality is better, the difference is smaller, if the general comparison test, often can not tell the true difference in treatment, and even because of the error of individual cells larger, and affect the average square of the difference
