The medium japonica rice cultivated by state-owned farms in Shanghai has been dominated by “89-79” for more than 10 years. The variety of grain weight spike, in order to win the land reclamation grain yield contributed. However, in recent years, the degradation of “89-79” traits, especially the number of primary shoot degeneration at the base of ear stems increased, the panicle size became smaller, which seriously affected the yield. In order to meet the needs of two fundamental changes in agriculture, this year we introduced “95-16” new Japonica varieties from Wujin in Jiangsu Province to participate in the regional trial of the unified organization of the Bureau. The results identified the variety after all, a high
