野生二粒小麦与野生燕麦杂交F_2共61株,其中抽穗前(?)亡和黄化未能抽穗的共21株。分离出野生二粒小麦型、硬粒小麦型、斯卑尔脱小麦型、燕麦型和普通小麦型。野生二粒小麦型结实率11.2～63.5%,PMC染色体数为27～36。硬粒小麦型结实正常,PMC染色体数为2n=14″。斯卑尔脱小麦型结实率2.7～43.4%,PMC染色体数为37～50。燕麦型结实基本正常,PMC染色体数为41～43,出现1～2个单价体。普通小麦型的护颖包裹籽粒较松,不断穗节,容易脱粒,染色体数为39～45,结实率1.2～68.2%。杂种F_2不同类型植株的PMC染色体数为27～50,每株能抽穗扬花的植株都能结实,结实率1.2～92.3%。杂种F_2的小麦型中有一部分植株的芒长在外颖背上,表现出燕麦族的分类特征性状。
There were 61 F 2 hybrids between wild bred wheat and wild oats, among which 21 were dead and etiolated before heading. Two durum wheat, durum wheat, spelled wheat, oat and common wheat were isolated. Wild double grain type of seed set rate of 11.2 to 63.5%, PMC chromosome number of 27 to 36. Triticum durum was normal, and the number of PMC was 2n = 14 ". Spelled wheat showed a seed setting rate of 2.7-43.4% and a PMC of 37-50. Oat-type was basically normal and PMC was 41-43 , And 1 to 2 monovalent species appeared.It was found that the seeds of common wheat type were more loose and spikelets and threshed easily, the number of chromosomes was 39-45 and the seed setting rate was 1.2-68.2% .PMCs of hybrid F 2 plants 27 ~ 50, the plants of heading and flowering per plant were able to bear fruit, the rate of seed setting was 1.2-92.3% .Monotypes of Oats belonging to the genus Oats were found on the dorsal surface of some plants in hybrid F_2.
