引种杂交粳稻在哈尔滨的生长发育研究

Growth Development of Introduced Hybrid Japonica Rice Research in Harbin

以国家杂交水稻工程技术中心天津分中心提供的H5/LK60、H5/H15、H5/R48、H5/R42、垦稻12/R48、垦稻12/R42、垦稻12/LK60、垦稻12/H15和垦稻12/花28杂交粳稻为试验材料,在哈尔滨生态区域进行了栽培试验研究。结果表明:杂交粳稻在寒冷地区具有明显的杂交优势,与当地普通水稻品种相比返青早,分蘖能力强,穗数和穗粒数多,库容量大,在2010年没有遇低温情况下,其产量比对照平均增加25%左右,在哈尔滨市具有广阔的市场前景。

Nine hybrid japonica rice materials（H5/LK60,H5/H15,H5/R48,H5/R42,Kendao 12/R48,Kendao 12/R42,Kendao 12/LK60,Kendao 12/H15 and Kendao 12/Hua 28）,providing by Tianjin Branch of China National Hybrid Rice Technology Center,were cultivated in Harbin.The results showed that the hybrid japonica rice varieties indicated advantages in cold region compared to the local ordinary rice.They were reviving more early,stronger ability of tillering,more panicles and grains per spike,and larger storage capacity.There is no case of low temperatures during 2010,under the condition,the yield increasing by nearly 25%.They had a broad prospect in Harbin.
