摘要: 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。

Abstract: Based on AMMI model, the genotype (G) ×environment (E) interaction on the grain’s milling quality of 25 rice cultivars from Liaoning Province was studied, with the stability of the milling quality in relation to the eco-climatic adaptability of these cultivars discussed. The results showed that there existed significant differences in the brown rice rate and head milling rice rate among different sites, varieties, and G×E interactions. The cultivars with high stability in brown rice rate were V12 (Huajing 49), V3 (Liaojing 294), and V4 (0163), while those with high stability in head milling rate were V3, V1 (XianS 38), and V18 (LDC 248). For brown rice rate, cultivars V15 (Shennong 9810), V19 (Yutian 301), and V7 (Qiao 201-2) had special eco-climatic adaptability to low or high temperatures; for head milling rate, cultivar V22 (Ying 9207) presented special eco-climatic adaptability to high temperature, V11 (0157) to low temperature and drought, and V15 (Shenong 9810) and V16 (Longpan 5) to rainless or pluvial conditions, respectively.
