一.去年3月间,我们就开始了稻谷替换胚乳的试验工作,参加这个实验的工作人员,是由作者担任指导,由米丘林生物科学研究小组倪懋樟、卢寿根两个工作组,担任管理工作,工作方法是这样的: (1)材料我们选择了当地的晚糯稻憨糯品种(以下简称糯稻)和当地的一季粳稻七月搓品种(以下简称粳稻),这两种稻的特性,是有明显区别的:糯稻的粘性强,它的分叶力强;粳稻米较硬,且分叶力弱。我们这样选择,是根据了米丘林学说:用习性有明显区别的植物,杂交后所产生的后代其变异是比较大的。我们希望获得一种不软不硬适宜煮饭,而分叶力强,可以提高产量的新类型稻的品种。 (2)嫁接根据当地农业实践的经验。“清明播种,谷雨插秧。”我们在四月七日把选好的两种稻谷,在培养皿内萌发,到胚根突出种皮时,用安全剃刀片, In March last year, we started the rice replacement endosperm test work, to participate in the experiment staff, is the author as a guide, by Michurin biological research team Ni Mao Zhang, Lu Shougen two working groups, as management work , The working methods are as follows: (1) Material We chose the local glutinous rice of late waxy rice (hereinafter referred to as glutinous rice) and the local japonica rice of July rubbed variety (hereinafter referred to as japonica rice). The characteristics of these two kinds of rice are Obvious difference: glutinous rice sticky strong, strong leaf division; japonica rice is harder, and leaves weak. We make this choice based on the theory of Michurin: Plants with marked differences in their habits have relatively large variations in the offspring produced after the cross. We hope to get a new type of rice that is not too soft or hard to cook, but leaves strong and yields high. (2) grafting according to local agricultural practices. “Ching Ming Seeding, Gu Yu Transplanting.” On April 7, we germinated the two selected types of rice in petri dishes. When the radicle was prominent on the seed coat, we used a safety razor blade,
