众所周知,小麦属的各个种每朵花只结一粒种子,虽然有的资料也曾报道过结二粒、三粒种子(复合粒)的现象,但多是在一个麦穗的少数花中出现,同时它们也多不遗传,或者其遗传性很不稳定。现在我们所发现的这个小麦与前者不同的是它的每朵花都生有三个雌蕊,结三粒种子(图版Ⅰ,1、2、)。这三个雌蕊或三粒种子生长的部位一定,形状稳定,不论在什么条件下试种都可呈现,遗传性是稳定的。具此我们就叫它为“三粒小麦”(Trigrain wheat)。很明显,这一性状的形成在小麦的基因库里无疑是增添了一个新的“三粒基因”。 It is well-known that each species of the genus Triticum has only one seed per flower. Although some data have reported the phenomenon of two or three seeds (composite grains), they are mostly found in a few flowers of a wheat , And at the same time they are often not inherited or their heredity is very unstable. Now the wheat we find is different from the former in that it has three pistils per flower and three seeds (Plate I, 1, 2,). The three pistils or three seeds of the growth of the site must be stable shape, no matter under what conditions can be demonstrated, hereditary stability. With this we call it “Trigger wheat”. Obviously, the formation of this trait undoubtedly adds a new “three-gene” to the wheat gene pool.
