| 摘 要： | 栽培稻籼粳亚种间F1代杂种优势与双亲关系极为密切，不同类型组合间差异甚大。本文从籼粳稻的细胞质效应差异性、籼粳稻的生态型组合的差异性、不同分化程度的亚种组合差异性等几方面总结了近一二十年来水稻各有关的经济性状与生物性状在籼粳亚种间F1代利用中的遗传特点的研究，并重点分析了生育期、株高、充实度3个性状，以期为亚种间杂种优势利用时亲本的选配提供一定的参考依据。

| Abstract: | The phenotype of F1heterosis between Indica and Japonica is mostly decided by their parents.Great differences exist in different crosses.From the aspects of the difference among effects of cytoplasm ofIndica and Japonica,the difference of parental ecotype crosses,the difference of subspecific crosses of variousgenetic differentiation,we sum up the recent research on genetic characteristic of some biological charactersand economic characters when utilizing F1 heterosis of Indica-Japonica.Days of maturity, plant height andgrain filled proportion were analyzed in detail at the same time.This can instruct us to some extent to selectparents for utilization of F1 heterosis beween Indica and Japonica rice subspecies. |
