| Abstract: | In view of the existing problems in the development of japonica hybrid rice in Northern China, the authors proposed the research orientation and technical approaches for japonica hybrid rice breeding on the basis of the breeding practices of many years. a) Correctly understand and utilize heterosis in rice. By way of raising yield potential of both parents and making use of the additive effects of genes to increase the standard heterosis of F 1 hybrids; To improve grain quality of F 1 hybrids, the breeding of quality parents should be intensified because of the negative heterosis in some grain quality characters. b) Ideal plant type should be paid more attention to in japonica hybrid rice breeding. The plant types of both parents should be favourable not only to a full play of F 1 heterosis but also to hybrid seed production. c) Explore new germplasms such as japonica male sterile lines with dominant semi-dwarf genes and transgenic herbicide-resistant japonica restorer and enhance the use of them. |
