对含有不同的主效矮杆基因（Ｒｈｔ１，Ｒｈｔ２和Ｒｈｔ１＋Ｒｈｔ２）的三组春小麦品种进行了两年，两地的试验。结果为；具有Ｒｈｔ１半矮杆基因的组以较高的生物产量、穗粒数和每平方米穗数来提高籽粒产量；具有Ｒｈｔ１和Ｒｈｔ２的矮杆组，通过提高千粒重，增大收获指数来获得高产；在两个半矮杆组内，籽粒产量和株高，每平方米粒数和千粒重均为显著负相关，矮杆组内的籽粒产量和每平方米粒数，生物产量及生物产量比率，生物产量与每平方米粒数，均呈极显著正相关。不同的品种的不同的矮杆基因的构成，形成了各性状间不同的相关关系。
Three groups of spring wheat cultivars with different major and minor dwarf genes (Rht1, Rht2 and Rht1 + Rht2) were tested for two years and two years. The results showed that the group with Rht1 gene had the highest biomass, the number of grains per spike and the number of spike per m2 to increase the grain yield. The short rod group with Rht1 and Rht2 increased the grain yield by increasing the grain weight In the two semi-dwarf groups, grain yield and plant height, grain number per square meter and grain weight were significantly and negatively correlated. The grain yield and grain yield per square meter, biomass yield and biomass yield in the short bar group, Biomass yield and grains per square meter, were significantly positive correlation. Different varieties of different dwarf genes constitute the formation of a variety of different relationships between traits.
