| 摘 要： | 元江普野(普通野生稻)栖生地远离栽培稻,生活周期属多年生野生稻,套袋自交后代不分离,酯酶同工酶 EST-X 位点分析显示为纯合型普野。多数形态特征分析属典型普野,未见明显的籼粳分化。同工酶分析结果则不同。酯酶上偏籼,过氧化氢酶上则偏梗。两种同工酶上表现不一致似乎表明,元江普野具有籼粳分化的可能性。元江普野在酯酶上接近南亚与东南亚普野,其过氧化氢酶又类似中国其他各省的普野,使它在追溯中国栽培稻的起源与演化上具有重要意义。

| Abstract: | The CWR(common wild rice)in Yuanjiang Yunnan is habitated far from cultivated rice. Its life-history shows a perennial type.There exists no segragation in its progeny when self-pollinated by bagging.As far as the esterase isozyme locus Est-X is considered,it is a homozygous kind of CWR.More- over,it belongs to a typical CWR and no obvious Indica-Japonica differentistion.But isozyme analysis indi- cates the opposite results,that is,an Indica-like electromorph in esterase and Japonica like electromor- phain c... |
