以8个不同来源的高矮秆大麦品种进行7个组合的杂交,研究了它们的矮秆及其有关性状的遗传规律。结果得出,控制大麦矮秆性状基因的遗传有两种类型:一种是一对基因的矮秆遗传,这对基因包括涡型矮秆基因uz,它与密穗基因1c连锁。从国外引进的两个品种和我国西藏的一个品种属于这一类型。另一种是多对基因的矮秆遗传,已确定是2—3对,它们实际 Seven combinations of high-barley barley cultivars from eight different sources were crossed to study the genetic rules of their dwarf and its related traits. The results showed that there are two types of genetic control of barley dwarf trait genes: one is the dwarf inheritance of a pair of genes, including vortex dwarf gene uz, which is linked to the spike gene 1c. Two varieties introduced from abroad and one species in our country belong to this category. The other is the dwarf heredity of pairs of genes, which have been identified as 2-3 pairs, which are actual
