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穗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％。

Abstract: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. Sixfor
