摘　　要：将粗山羊草细胞质导入普通小麦 ,研究其对普通小麦细胞核的遗传效应。结果表明 ,粗山羊草细胞质对普通小麦开花习性具有优良的作用 ;能增加小麦的株高 ,提高小穗数、穗粒数、结实率和发芽势 ,但延迟小麦的生育期 ;对其他性状影响不显著 ;粗山羊草细胞质对普通小麦细胞核之间有一定的核质杂种优势。The genetic effects of Aegilops squarrosa L. cytoplasm were studied by transferring Aegilops squarrosa L. cytoplasm into wheat. The results showed that Aegilops squarrosa L. cytoplasm had fine effects on wheat flowering habits and characteristics.Meanwhile, plant height, number of spikelets, grains per spike,setting rate and germinating potential of wheat were improved significantly, but wheat growth phase was lengthened. There were no significant effects on other agronomic characters. There was sure nucleo-cytoplasmic heterosis between Ae. squarrosa L. cytoplasm and wheat cell nucleus.
