| 摘 要： | 对6个不同生态类型小麦品种及其完全双列杂交F1幼穗分化特点和穗分化杂种优势的研究表明,杂种幼穗分化各主要时期普遍存在杂种优势;不同生态类型组配方式的杂种穗分化优势不同;穗分化杂种优势与产量杂种优势具有一定相关关系;黄淮麦区杂交小麦最佳生态组配方式为春性品种×冬性品种。

| Abstract: | Exogenous DNA directly introduced into wheat plant induced striking change in seed protein components of wheat and isozymogram of peroxidase isozyme (POD),esterase isozyme (EST) and superoxide dismutase (SOD).The proteins increased by 44 ku,67 ku,85 ku new compoents,and the protein and amino acid contents enhanced by 16.85% and 15.62% separately,Lys increased by 42.94%.Isozyme also showed difference isozyme bands,losing isozyme bands and increase and decrease of enzyme activity in varying degrees.Some bio characteristics of variant grains derived from introducing exogenous DNA into common wheat,such as colour,hardness,endosperm trasparency etc,also showed remarkable changes.These variations can be stably expressed in successive progenies. |
