摘　　要：介绍了一种新型玉米单倍体诱导系,该诱导系兼具籽粒标记、幼苗标记和成株标记,可在幼苗期通过黄绿苗性状鉴别出杂合二倍体植株,可在早期加倍(EDH)、高自然加倍、单倍体回交和单倍体轮回选等技术方面应用,有明显的技术优势与应用前景。This paper disclose a novel maize haploid inducer. This inducer with kernel marker, vegetative marker and plant marker to identify haploid plants. It can indentify heterodiploid plants by yellow-green seedling marker at seedling stage. It can be widely used in EDH(early spontaneous doubled haploid), high spontaneous doubling, haploid backcross and haploid recurrent selection technology in maize breeding scheme.
