基于AMMI模型,研究了辽宁省25个水稻品种碾磨品质的稳定性,并对基因型×环境(G×E)互作与气候因子的关系进行了探讨。结果表明:糙米率和整精米率在不同试点间、品种间及G×E互作间差异极显著;糙米率稳定性高的品种有V12(花粳49)、V3(辽粳294)和V4(0163)等,整精米率稳定性高的品种有V3、V1(仙S38)和V18(LDC248)等。糙米率的气候生态适应性表明:品种V15(沈农9810)、V19(雨田301)和V7(桥201-2)分别对低温和高温的环境有特殊的适应性;整精米率的气候生态适应性表明品种V22(营9207)对较高温度的环境有特殊适应性,品种V11(0157)对相对低温和少雨的环境具有特殊适应性,而品种V15(Shenong9810)和V16(龙盘5号)分别适应相对少雨和多雨的环境。
Based on the AMMI model, the stability of milling quality of 25 rice cultivars in Liaoning Province was studied. The relationship between genotype × environment (G × E) interaction and climatic factors was also discussed. The results showed that the brown rice rate and milled rice rate were significantly different among different experimental plots, among varieties and among G × E intercropping varieties. The varieties with high brown rice rate stability were V12 (Huajing 49), V3 (Liaojing 294) and V4 (0163) and so on. There are varieties of V3, V1 (Sin S38) and V18 (LDC248) which have high stability of milled rice. The climatic and ecological adaptability of brown rice showed that the varieties V15 (Shennong 9810), V19 (Yutian 301) and V7 (Bridge 201-2) had special adaptability to low temperature and high temperature respectively. The climatic ecological adaptation The results showed that the cultivar V22 (Camp 9207) had special adaptability to higher temperature environment. Variety V11 (0157) had special adaptability to relatively low temperature and little rain, while V15 (Shenong9810) and V16 (Longpan No.5) Respectively to a relatively dry and rainy environment.
