人工合成的八倍体小黑麦85-196的染色体数为2n=56,株高、穗长及小穗数居双亲之间,偏低、偏长、偏少,每穗结实粒少,种子不饱满。受精过程与其亲本基本相近,但胚和胚乳发育过程中淀粉粒分布状况与其亲本有区别,受精后不能正常发育(败育)的种子占有一定比例。认为八倍体小黑麦籽粒不饱满和结实率低的主要原因是胚乳发育不正常所致。 The chromosome number of the synthesized octoploid triterpenes 85-196 was 2n = 56. The plant height, spike length and spikelet number were between parents, and were low, long, Not full. The process of fertilization was similar to that of their parents, but the distribution of starch granules in embryo and endosperm was different from that of their parents, and the seeds that could not normally develop (abortion) after fertilization occupied a certain proportion. The main reason that octoploid triticale is not plump and low in seed setting is the abnormal development of endosperm.
