宿迁市2021年杂交中籼稻品种安全性测试

Security Test of Planting Medium Indica Hybrid Rice Varieties in Suqian City in 2021

宿迁市引进的杂交稻多为国家长江中下游地区审定品种,因宿迁不在审定品种的种植范围,加快推广可能存在一定的种植风险。本研究以宿迁市范围内引进种植的部分杂交稻品种为供试材料,通过调查其全生育期生长发育、农艺性状及产量特性,以期筛选出适合宿迁地区推广种植的高产、稳产杂交稻品种。结果表明:徽两优001、荃9优220、9优粤禾丝苗、千香优220、徽两优福星占、徽两优华占、徽两优粤禾丝苗和徽两优996的产量、生育期、农艺性状等综合表现较好,较适合宿迁地区推广种植;高产品种赣优735、优质品种19香和悦两优美香新占等品种在加强栽培技术配套开发的条件下,也适宜在宿迁地区推广种植。

Most of the hybrid rice varieties introduced into Suqian City were appraised in the middle and lower Yangtze River reaches.Because Suqian City was not within the areas where these varieties were appraised for their field performance, there might be certain risks for planting these introduced varieties in Suqian. Therefore, this study investigated 20 introduced hybrid rice varieties for their characteristics during the whole growth period in a field trial performed in Suqian City in 2021 in order to select the varieties with a high-yielding capacity, yield stability, and suitability for planting in Suqian area. The results are as follows: the hybrid rice varieties Huiliangyou001, Quan9you220, 9youyuehesimiao, Qianxiangyou220, Huiliangyoufuxingzhan, Huiliangyouhuazhan, Huiliangyouyuehesimiao,and Huiliangyou996 showed good comprehensive performance in the field with respect to yield, growth period, and agronomic traits;thus they are more suitable for planting and promotion in Suqian city than the other tested varieties. In addition, the high-yielding variety Ganyou735 and high-quality varieties 19xiang and Yueliangyoumeixiangxinzhan are also suitable for extension in Suqian area under the condition of strengthening the development of supporting cultivation techniques.
