It can be used as single season or late season new indica hybrid rice combination. Having passed provincial level yield trials in the following years, it was released in 1990 with the permission of Zhejiang Provincial Government, later on recommended as one of the top commercial hybrid rice combination by China State Science and Technology Commission. By the end of 1992, Xieyou 46 has been planted as a late season or single season hybrid ricc combination along the middle and lower reaches of the Yangtze River, and the planting area has reached 3.35 million ha. It has become one of the most important late season hybrid rice combinations in Zhejiang Province. Characteristics of Xieyou 46: Xieyou 46 has a suitable growth duration of 125-130 d as late season rice or 127-134 d as single season rice, 2-3 d shorter than those of Shanyou 6. It bas a compact plant type, high tilleri展开更多
