小麦异细胞质效应的研究

采用四种异细胞质“中国春”小麦即（Ｔ．ＺｈｕｋｏｖｓｋｉＧ）ｃｓ，（ＡｅＭｕｔｉｃａＭ）ｃｓ（Ａｅ．ＶａｒｉａｂｉｌｌｉｓＳ）ｃｓ（Ａｅ．ＣｒａｓｓａＤ＾２）ｃｓ与普通小麦“哈师一号”杂交，探讨异细胞质的效应。结果表明：不同细胞质对杂交当代的结实率，种子饱满度，发芽率，Ｆ１的株高，分蘖数，穗长，生育期，育性的不同的影响，特别是育性差异较大，Ｆ１的减数分裂行为：在Ｇ型，Ｍ＾ｔ型细胞质Ｆ１植株中出现少

STUDY ON THE ALLOPLASMIC EFFECT OF WHEAT

The purpose of the experiment is that, Four alloplasm of Triticum aestivum cv, Chinese Spring With the cytoplasms of Aegilops, that is,T.Zhukovskyi(G type), Ae.Crassa(D 2 type), Ae.Mutica(M t type)and Ae.variabilis(S v type), were used as female paren.which respectively were crossed with male parent Ha shi one (AABBDD), All the nuclear genotype of F1 hybrid generation were compele the same. Under this condition, according to the difference among the character of F1 generation, we can discuss the effect of cytoplasm.
