水稻新品种淮香粳15号丰产性、稳产性及适应性分析

Yield,Production Stability,and Adaptability of a New Rice Variety,Huaixiangjing 15

淮香粳15号是2013年通过江苏省农作物品种审定委员会审定的水稻新品种。为了更全面地了解水稻新品种淮香粳15号的生产特性,利用2011、2012年江苏省水稻晚粳迟播区域试验资料,通过t检验、变异系数和回归系数等方法,分别对淮香粳15号及对照品种(南粳44、武运粳23)的丰产性、稳产性和适应性进行分析和比较。结果表明:淮香粳15号的丰产性、稳产性和适应性均明显地优于对照品种,综合性状优良,是一个较为理想的高产迟熟中粳稻新品种。

Huaixiangjing 15（coded Huai 6188）was a new rice variety certified in 2013 by the Crop Approval Committee at Jiangsu Academy of Agricultural Sciences.Using the data collected from the regional trials on the latesowing,late-mature Japonicarice in Jiangsu during 2011-2012,the variation and regression coefficients from a t test analysis on the fertility characteristics,production stability,and adaptability of Huaixiangjing 15 were compared with those of Nanjing 44 and Wuyunjing 23（CK）.The results showed a significant superiority of the new variety over CK on all those aspects.It was,thus,considered a newly added desirable late-maturing,high-yield,mediumgrain Japonicarice.
