摘要
利用AMMI模型对18个水稻品种的食味品质性状——米饭光泽度、粘性、柔软性、弹性和综合口感进行了2年3点的稳定性分析,并以食味品质性状的表型值和AMMI分析的前三维主成分值(IPCA1～3)为性状指标,对18份供试品种进行了聚类分析和评价。结果表明,5项食味品质指标在不同基因型、地点和年份间的差异以及G×E互作方差都达到极显著水平(P<0.01);不同栽培方式也能显著地影响稻米食味品质,且对各项食味指标的作用方向完全一致,即绿色食品栽培>有机栽培>常规栽培>高产栽培;粳稻品种的食味品质及其稳定性整体上要优于籼稻品种,其中食味品质好且稳定性高的籼、粳品种有 W002、早丰九号、武育粳 3号、广陵香粳、盐粳 5号、3004、丰优香占、R405和南京16号。综合考虑品种的产量水平和外观品质,W002、丰优香占、南京16号等可作为育种亲本,以改良水稻品种的食味和外观品质及其稳定性。
Investigation on stability of rice-eating quality, including luster, viscosity, tenderness, elasticity and integrated valueof organleptic evaluation (IVOE) of 18 varieties wascarried out using additive main effects and multiplicative interaction (AMMI) model in three sites and two years. Eighteen tested varieties were further clustered and evaluated based on the phenotypic values of five palatability properties and IPCA 1-3 from the AMMI analysis. Results showed that genotype by environment interactions and the eating quality differences between different genotypes, sites and years were all significant at 1% level. Meanwhile, different cultivations could significantly affect the five rice-eating quality traits with the samedirection, namely, green food cultivation > organic cultivation > common cultivation > high production cultivation. In general, the five palatability properties and their stability in Japonica varieties were better than those of Indica varieties. Five Japonica varieties and four Indica varieties, which included W002, Zaofeng9, Wuyujing3, Guanglingxiangjing, Yanjing5, 3004, Fengyouxiangzhan, R405, Nanjing16, had good eating quality and high stability. In consideration with the grain production, appearance quality, etc., W002, Fengyouxiangzhan and Nanjing16 could be applied as breeding parents to improve the eating and appearance quality and their stability of elite rice.
