It performs well in yielding, lodging resistance, disease resistance, with a short duration of growth. Therefore, it is suitable to be grown in tropical areas and countries such as Myanmar and Indonesia. The male parent contains herbicide susceptible lethality gene and it is possible for mechanical mixed planting. The research analyzed performance of Hunyou No. 2 growth in Myanmar and the results showed that Hunyou No. 2 performed better in yield, panicle length, the number of seed per panicle, setting percentage, and thousand-seed weight than She thwe yin, as well as lodging resistance, disease resistance and quality. Some high-yielding cultivation measures have been concluded including sparsely sowing, densely planting, highlighting base fertilizers, and avoiding early water breaking.展开更多
