[ Method] Four- teen new rice varieties included in the Middle-ripe Japon/ca Rice Regional Test in 2011 were selected as the materials. Correlation analysis and cluster analysis were carried out on their quality traits. [Result] The rice cultivars possessed stable characteristics, which were difficult to be further improved. In addition, their quality traits had extremely complicated relationships, and the differences were significant between different groups. [ Conclusion] This study will provide reference for improving the quality traits of japonica rice.展开更多

[Method] The fruit botanical and quality characteristics of the seven litchi varieties introduced into Northern Mountainous Agriculture and Forestry Science Institute of Vietnam Academy of Agriculture Sciences were compared and analyzed. [Result] Three varieties with good general qualities including Lai Phu Ho,Thach Binh and Hung Long which were suitable to be cultivated in the local area were selected. In addition,Phu Dong was the available,early-maturing germplasm resource. [Conclusion] This research will provide reference for litchi production and breeding in northern mountainous area.展开更多
