摘　　要：在麦类作物多胚的研究中，我们在２４个二棱大麦品系中，发现品系ＨＤ－２１的侧生小穗发育，且因位置偏移与中间小德合生或粘连，造成多胚的赝象．合生或粘连有６种形式，是可遗传的，遗传给后代植株的出现频率平均为１５．３８％，穗部出现合生或粘连的小穗一般为２％左右，最高达５０％。Developing lateral spikelets were found in HD-21 among 21 lines in two-rowed barley. Because developing lateral spikelets took place change of position, they merged orjoined with medium spikelets so that the false appearance of polyembryony formed. Sixforms were inheritable. The character in hereditable progencies was average 15. 38%.The spikelets merged or joined in a spike was about 2%,the maximum was 50%.
