禾本科植物的无性杂交,近年来在国内外都进行了许多工作,获得了不少成就。但一般多用麦类材料移胚嫁接,以水稻做材料的比较少,因为水稻的胚乳与麦类的胚乳有所不同,它的粘性很小,胚接时很难贴紧,容易脱离,成活困难。然而水稻是我国的重要作物,且其中存在许多值得研究的问题,例如籼稻和粳稻,它们的性状相差很大,在经济价值上各有优缺点,若能把二者的性状结合为一,取长补短,无疑是可以提高产量,改良品质的。可惜籼、粳稻进行有性 Gramineous hybrids, in recent years at home and abroad have carried out a lot of work, has made a lot of achievements. However, the general use of wheat material transfer embryos grafted to rice to make the material is relatively small, because the endosperm and wheat germ endosperm is different, its viscosity is very small, easy to cling to the embryo, easy to detach, survive difficult . However, rice is an important crop in China and there are many problems to be studied. For example, indica and japonica rice have great differences in their traits and have their own advantages and disadvantages in economic value. If we can combine the traits of the two into one, , Undoubtedly can improve production, improve quality. Unfortunately, indica and japonica are sexual
