Biological Characteristics and Cultivation of Disease-resistant New Rice Variety,Guyou 627
-
摘要: 2年的区域试验表明, 谷优627表现抗稻瘟病, 产量较高, 稳产性好, 适应性广。相关、通径分析结果表明, 穗总粒数、单位面积有效穗对产量的贡献率都较大, 分别达47.32%和39.84%, 穗总粒数与产量呈显著正相关 (r=0.4392*) 。高产栽培策略是创建理想的高产群体, 协调穗粒结构, 在合理密植的基础上, 主攻穗总粒数。提出了配套高产栽培与制种技术。Abstract: The new Guyou 627 rice exhibited a strong resistance to rice blast and high and stable yield as well as wide adaptability during a two-year regional trial.The correlation and path analysis showed that the desirable panicles per unit area and grains per panicle contributed to its high yield.Information on the cultivation and production of this new rice variety is presented.
