以７９个改良小麦品种（系）与黑麦进行杂交，研究普通小麦品种与黑麦杂交亲和性的差异及其亲和性在品种更新、更换过程中的演变趋势，结果表明：供试改良小麦品种与黑麦的杂交亲和性显著低于对照中国春；结实率大于５０％的品种３个，占供试品种的３．８％，结实率介于３０％－５０％之间的品种４个，占５．１％，结实率介于１０％－３０％之间的品种８个（１０．１％），结实率小于５％的品种５０个，占６３．３％，另外，结实率介于５％－１０％之间的品种１４个，占１７．７％；普通小麦与黑麦的杂交亲和性随着品种的更新、更换呈下降趋势，平均结实率大于５０％、介于３０％－５０％的品种数均呈下降趋势，而结实率＜５％的品种数呈上升趋势；系谱分析表明，供试改良品种的亲和性大都来源自蚰子麦、蚂蚱麦、辉县红３个地方普通小麦品种；莱州９５３、８６４１０１２、烟农１５等是亲和性和综合性状都较好的改良小麦品种（系）。
The crosses of 79 improved wheat cultivars (lines) with rye were conducted to study the differences in the compatibility of common wheat cultivars and rye crossings and their evolutionary trends during the process of renewal and replacement. The results showed that: The hybrid compatibility of wheat varieties and rye was significantly lower than that of the control Chinese spring. Three varieties with the seed setting rate above 50% accounted for 3.8% of the tested varieties and the seed setting rate was between 30% and 50% 4 species (5.1%), 8 species (10.1%) with seed setting rate of 10% -30%, 50 species (63.3%) with seed setting rate of less than 5%. In addition, 14 varieties, accounting for 17.7%, were between 5% and 10%. The hybrid compatibility of common wheat and rye decreased with the renewal of varieties, the average seed setting rate was more than 50% The number of cultivars in the range of 30% -50% showed a downward trend, while the number of cultivars with the rate of <5% showed an upward trend. The pedigree analysis showed that most of the tested cultivars had their affinity originated from razor barley, Huixian red Local wheat varieties common; Laizhou 953,8641012, 15 farmers and other affinity and is better integrated traits are improved wheat varieties (lines).
