摘要
对2017—2019连续3年参加同一试点区域试验的5个水稻新品种的产量及田间抗性进行了分析比较,并通过高稳系数法(HSC)和变异系数(CV)分析了不同品种的丰产性及稳定性。结果表明:不同品种间的产量存在一定差异,但5个参试品种与对照相比均无显著性差异,金农香粳1267的产量显著低于银香38和沪软1212的。综合考虑高稳系数、变异系数及田间抗性表现,丰产性和稳定性较好的品种为银香38、光明粳3号和金农香粳1267。3个品种的HSC值和CV值均高于对照,且田间抗性表现良好,今后可进一步扩大推广。
The yield and resistance of five new rice varieties participating in the same pilot regional experiment for three consecutive years from 2017 to 2019 were analyzed and compared.High stability coefficient(HSC)and coefficient of variation(CV)were used to analyze the yield and stability of different varieties.The results show that there are certain yield differences among different varieties,and there are no significant differences among the five tested varieties compared with the control.However,the yield of Jinnongxiangjing 1267 is significantly lower than that of Yinxiang 38 and Huruan 1212.Finally,considering the high stability coefficient,variation coefficient and field resistance performance comprehensively,it is concluded that the varieties with high yield and stability are Yinxiang 38,Guangmingjing 3 and Jinnongxiangjing1267.The HSC and CV of the three were higher than those of the control,and the field resistance of the three was good,which was suitable for further expanding the promotion area.
