摘要:

【目的】选育高产、优质、综合抗性强的水稻新品种,为江苏省优质稻生产及粮食安全提供保障。【方法】2004年以银玉2239为母本、淮238为父本组配,连续多年多世代进行单株选择,2009年选择稳定品系(淮6188)进行小区品比试验,2010~2013年分别参加江苏省水稻预备试验、区域试验及生产试验,对其主要农艺性状、品质、抗性及产量性状进行评价,并研究其配套栽培技术。【结果】淮香粳15号具有高产、稳产、优质、适应性广等特点,全生育期150 d左右,株高109.0 cm,每穗平均粒数125粒左右,结实率93.4%,千粒重28.0 g。2010年参加江苏省预备试验,淮香粳15号平均产量为10422.8 kg/ha,较对照武运粳23增产8.30%;2011~2013年参加江苏省区域试验和生产试验,平均产量分别为9513.4、10010.1和10408.5 kg/ha,分别较对照武运粳23增产5.07%、12.49%和6.00%。2014年通过江苏省农作物品种审定委员会审定。【结论】淮香粳15号具有高产稳产、优质、综合抗性强等特点,适宜在江苏沿江及苏南地区迟播种植。

【Objective】The present study was conducted to breed rice new variety with high-yield, high-quality and strong comprehensive resistance, in order to provide supports on high-quality rice production and grain safety in Jiangsu province. 【Method】In 2004, Yinyu 2239 as female parent and Huai 238 as male parent was crossed to obtain F1. Through individual selection of consecutive years, one stable strain(Huai 6188) was selected to conduct the variety comparative test in 2009; its comprehensive trait performances viz., agronomic traits, quality, resistance and yield related traits were investigated in preliminary trial, regional trial(two years) and producing trial of Jiangsu province during 2011-2013. 【Result】Huaixiangjing 15 was characterized by high-yield, stable-yield, high-quality, wide adaptability, etc. Huaixiangjing 15 showed about 150 days of duration, 109.0 cm of plant height, 125 grains per panicle, 93.4% of seed setting rate and 28.0 g of 1000-grain weight. The yield of Huaixiangjing 15 was 10422.8 kg/ha in Jiangsu preliminary test in 2010, which was increased by 8.30% as compared to the control Wuyunjing 23. The average yield of Huaixiangjing 15 was 9513.9, 10010.1 and 10408.5 kg/ha in Jiangsu regional trial and producing trial during 2011-2013, which increased by 5.07%, 12.49% and 6.00% as compared to the control Wuyunjing 23, respectively. It was approved and registered by Jiangsu Committee for Crops Variety Registration in 2014. 【Conclusion】Huaixiangjing 15, a new japonica rice variety with high-yield, high-quality and strong comprehensive resistance, is suitable for planting as late-maturing rice in riverside area or a late sowing rice in southern Jiangsu province.
