Yuexiang Zhan, a New Indica Rice Variety with High Harvest Index and High quality

Yuexiangzhan is the latest "high-efficiency index" conventional high-quality rice bred by the Rice breeding High-tech Research Laboratory of Rice Research Institute of Guangdong Academy of Agricultural Sciences. This variety passed the early conventional regional test in 1996 and 1997 and the mixed regional test of South China early indica conventional rice and hybrid rice in 1997 and 1998. In February 1998, it passed the provincial determination of crop varieties in Guangdong Province, and now it has become the corresponding species in the regional test of early and high quality millet in Guangdong Province. the variety popularized in the whole province, and listed in the extension project of the Ministry of Agriculture.
