2013年安徽省当涂县杂交水稻新组合品比试验

Variety Comparison Test of New Hybrid Rice Combinations in Dangtu,Anhui Province in 2013

[目的]选出适宜当涂县及相似生态区域种植的杂交水稻新组合。[方法]开展杂交水稻新组合联合鉴定试验,从丰产性、抗逆性、品质等方面进行考量。参试的19个杂交稻组合分别为谷丰A/886、58S/D1652、广占63S/1902、广占63S-4/856、乐丰A/R1699、58S/1848、乐丰A/11-478-3、农香A/1203、谷丰A/1203、隆74S/11-478-5、农香A/11-1182、1892S/886、双8S/1902、川香29A/1857、湘丰A/1848、96S/R1902、龙S/10-942、Ⅱ优838、炳1A/11-1182,以Ⅱ优838为对照。[结果]在当涂地区有一定优势的组合有8个,分别为1892S/886、广占63S/1902、广占63S-4/856、58S/1848、谷丰A/886、58S/D1652、隆74S/11-478-5、龙S/10-942。[结论]该研究可为当涂地区正确使用优良水稻品种,以加快当地水稻生产发展提供参考。

[ Objective] The aim was to find out the suitable new hybrid rice combinations for planting in Dangtu County and the similar ecological region. [ Method ] The joint identification test of new hybrid rice combinations were conducted on, and then considered from yield-increasing ability, resistance and quality. The 19 tested hybrid rice combinations were Gufeng A/886, 58S/D1652, Guangzhan 63S/1902, Guangzhan 63S-4/856, Lefeng A/R1699, 58S/1848, Lefeng A/11-478-3, Nongxiang A/1203, Gufeng A/1203, Long 74S/11-478-5, Nongxiang A/11-1182, 1892S/886, Shuang 8S/1902, Chuanxiang 29A/1857, Xiangfeng A/1848, 96S/R1902, Long S/10-942, II you 838 （CK）, Bing 1A/11-I 182. [ Result ] Eight hybrid rice eombinations had some advantages in Dangtu area, which were 1892S/886, Guangzhan 63S/1902, Guangzhan 63S-4/856, 58S/1848, Gufeng A/886, 58S/D1652, Long 74S/11-478-5, Long S/10-942. [ Conclusion] The study provides a reference for using good rice euhivars correctly in Dangtu area to speed up local rice production development.
