利用主效可加互作可乘(AMMI)模型、双标图以及稳定性参数Di对黑龙江省6个寒地水稻高产区的8个寒地水稻品种的数据进行稳定性分析。结果表明:垦粳1号最稳定,龙粳21、龙粳23在佳木斯市创业农场科技示范园区,东农425在五常市试验田具有特殊的适应性;在参试的品种中,品种稳定性从高到低为垦粳1号、中龙稻1号、龙稻5号、东农425、龙粳24、龙粳23、松粳12、龙粳21;在参试地点中,大兴农场科技示范园区、佳木斯市创业农场科技示范园区比较适合作为区试地点,各地点对品种鉴别力的大小依次为大兴农场科技示范园区>佳木斯市创业农场科技示范园区>五常市试验田>牡丹江市农业科学研究所>查哈阳农场科技示范园区>佳木斯市桦川县试验田。
The data of eight cold-paddy rice cultivars in six cold paddy high-producing areas in Heilongjiang Province were analyzed by AMMI model, double-plot plot and stability parameter Di. The results showed that Kenjing 1 was the most stable, Longjing 21 and Longjing 23 were in Jiamusi Entrepreneurship Farm Technology Demonstration Zone, Dongnong 425 had special adaptability in Wuchang experimental field. In the tested varieties, the stability of varieties from High to low were Kenjing 1, Zhonglong 1, Longdao 5, Dongnong 425, Longjing 24, Longjing 23, Songjing 12 and Longjing 21. Among the participating sites, Daxing Farm Technology Demonstration Park, Jiamusi City Venture Farm Science and Technology Demonstration Park is more suitable as a regional pilot sites, the location of the variety of the discriminative power of the size of the order of Daxing Farm Science and Technology Demonstration Zone> Jiamusi City Venture Farm Science and Technology Demonstration Zone> Wuchang experimental field> Mudanjiang Institute of Agricultural Sciences > Chahayang Farm Technology Demonstration Zone> Huachuan County Experimental Field in Jiamusi City.
