为掌握杂交中籼早熟水稻新品种安优5819的丰产稳产性和适应性,为其区域布局和生产应用提供实践依据,以2012-2013年贵州省杂交水稻区域试验结果为依据,采用均值-变异系数法和高稳系数法对安优5819(安丰A/黔恢5819)与对照品种(香早优2017)的10个主要表型性状的变异情况进行对比,综合分析该品种在不同生态环境下的性状变异。结果表明,安优5819的HSC值为83.2%~85.2%,高于CK;不同表型性状的平均变异系数在3.4%~17.7%,其顺序为有效穗>穗粒数>产量>穗实粒数>着粒密度>株高>结实率>全生育期>穗长>千粒重。结论:杂交中籼早熟新品种安优5819的综合性状好,高产稳产,生育期适中,抗逆性强,适应性广。
In order to understand the high yield, stability and adaptability of the hybrid rice variety “Anyiyou 5819”, which provides a practical basis for its regional layout and production application, based on the regional experiment results of Guizhou hybrid rice in 2012-2013, Coefficient method and high stable coefficient method were used to compare the variation of 10 major phenotypic traits of AnYou 5819 (Anfeng A / Guizhou Hui 5819) and the control variety (XiangzaoYou 2017) Under the character variation. The results showed that the HSC value of Anyian 5819 was 83.2% -85.2%, which was higher than that of CK. The average coefficient of variation of different phenotypic traits ranged from 3.4% to 17.7% with the order of effective panicles> grains per spike> yield> Number> grain density> plant height> seed setting rate> full growth period> ear length> 1000-grain weight. Conclusion: The new hybrid indica rice Variety Anyiyou 5819 has good comprehensive characters, high and stable yield, moderate growth period, strong resistance and wide adaptability.
