摘要
为选育适宜苏中地区种植的水稻新品种,选用淮稻14号为母本、徐23121为父本杂交配组,经多年系统选育而成迟熟中粳稻新品种"淮稻18号"。该品种具有丰产性好、品质优、综合抗性强等特点,其全生育期155.1d,株高98.7cm,每穗实粒数121.9粒,结实率92.4%,千粒重28.0g。2012-2014年参加江苏省水稻新品种区域试验,淮稻18号每667m2平均产量分别达到709.7、660.1和658.0kg,较对照淮稻9号分别增产8.64%、7.19%和13.47%。2015年通过江苏省农作物品种审定委员会审定,适宜在江苏省苏中及南京、镇江、扬州丘陵地区种植。
To breed a new rice variety suitable for cultivation in central Jiangsu,Huaidao 14 was crossed with Xu 23121.Through years of breeding and screening,a new mid-season-ripening Japonica rice,Huaidao 18,was selected.The new cultivar was characterized by high-yield,high-quality,strong over-all resistance,etc.It had an average growth period of 155.1 days,plant height of 98.7 cm,grain weight per panicle of 121.9 g,seed setting rate of 92.4%,and per 1000-grain weight of 28.0 g.In the 2012-2014 regional production trials in Jiangsu,it showed averagedannual yields of 709.7,660.1 and 658.0 kg·hm-2,representing the increases by 8.64%,7.19% and 13.47%,respectively,for each year as compared to the reference,Huaidao 9.Subsequently,Huaidao 18 was certified by Jiangsu Committee for Crops Variety Registration in 2015.The new variety was,therefore,considered suitable for scale-up cultivation in central Jiangsu as well as hilly areasin Nanjing,Zhenjiang and Yangzhou.
