Abstract: Intersubspecific hybrid rice showed obvious advantages on the accumulation of photosynthetic products and varieties of hybrid rice and conventional rice, but dry matter conversional rate was a bottleneck between subspecies in high yield hybrid rice. In this paper, subspecies hybrid rice dry matter conversional factors (subspecies physiological characteristics of hybrid rice, cultivation practices, ecological conditions, morphological, genetic mechanisms, molecular biology) and other aspects were generally reviewed, and summarized the relative characteristics between the source repository and cellular activity factor of subspecies hybrid rice. Therefore, the necessity of the relative research was proposed in this paper on the subspecies hybrid rice dry matter partitioning and screens and cellular structure activity.
