摘　　要：籼稻的诱发突变导致了生态特征改变 ,从而产生了早熟同型系。这与籼稻生态类型有密切关系 ,不同生态型品种诱发出不同水平的早熟同型系 ;反之 ,相同生态型品种产生相似的早熟同型系。在诱发早熟同型系中产生了早熟生态类型品种 ,这为加速生态型品种的形成和种质创新提供了依据及可能。The induced mutation in light sensetivity of the Indica rice leads to induction of the homologous series of early mutants along with the variation of ecological character and the ecoclimate. The induction of mutants was closely related to the ecotype of Indica rice, the homologous series of early mutants in different level were derived from the different ecotype of the Indica rice, otherwise, the similar homologous series of early mutants were derived from the same ecotypic variety. The induction of the early ecotypic variety derived from the homologous series of early mutants provides the basis and possibility for accelerating the development of the new cultivars.
