据有关研究,西瓜植株的全缘叶、短蔓、叶色黄斑、无毛等性状,均受隐性基因控制,利用具有这种隐性性状的品种作母本性状标志,不仅可以简化人工授粉杂交制种手续,而且可在苗期二、三真叶时区分出真假杂种,便于检验和保证杂交纯度。我国可作标志基因的全缘叶品种现有中育三号和板叶一号,但它们都是分别在华北、新疆等生
According to the research, watermelon plants all leaves, short vine, leaf color macular, glabrous and other traits, are controlled by the recessive genes, the use of this recessive traits as a maternal trait marker, not only can simplify artificial pollination Hybrid seed production procedures, but also in the seedling stage two or three true leaves distinguish true and false hybrids, easy to test and ensure the purity of the hybrid. The whole leaf species that can be used as a marker gene in our country are available in Zhongyu No.3 and Banye No.1, but they are all found in North China and Xinjiang respectively
