摘 要 ：对当年抽穗的62株小冰麦杂种 F_1再生植株的形态特征及染色体变异观察表明,杂种无性系变异十分明显:有倾向冰草、倾向小麦及产生特殊形态三种变异类型,其中倾向冰草的变异植株较多。杂种无性系的染色体变异率也较高:愈伤组织细胞染色体变异率为56.2%;41株再生植株中有19株发生染色体数目变异。杂种无性系还出现较多的表型嵌合

Abstract:Observations were made on the morphological characteristics and chromosome variations of 62 earing plants regenerated from wheat×wheatgrass hybrid F_1.These plants could be divided into three types according to their morphology.Including plants approachingwheatgrass,those approaching wheat,and thos
