摘要
本文对 4个新引入的美国玉米改良群体的植株和果穗的农艺性状进行了分析。结果表明 4个群体的农艺性状均存在较大的遗传差异,遗传基础广泛,具有丰富的可利用的基因类型。因此,可充分利用群体内存在的遗传差异。
We tested 4 original colony plant of maize and every agronomic characters of ear,and analyzed average value,variattion-coefficience variation degree and analysis of variance in colony of every character.The result showed that there was no dominant difference except several character between 4 colonies.There was dominant difference on several characters in colony.
