小麦新品种云麦72丰产稳产性及产量构成因素与产量的相关性分析
|
摘要
为了解小麦新品种云麦72的丰产稳产性、适应性及产量构成因素对产量的作用,利用云南省小麦2年区域试验和1年生产试验汇总资料,采用多种分析方法对云麦72的丰产性、稳产性及产量三要素与产量的相关性进行分析。结果表明,云麦72表现出丰产性突出、稳产性好和适应度广的特性;产量与有效穗和穗粒数均成极显著正相关关系,千粒重与产量相关不显著;有效穗对产量的直接作用最大,是其高产的主要因素。由此说明,云麦72在云南省生产上具有广阔的应用前景。
In order to understand the effects of high-yield,stable yield,adaptability and yield components on yield of new wheat variety Yunmai72,the data of two-year regional experiment and 1-year production experiment in Yunnan Province were used to analyze the correlation among three factors of high-yield,stable-yield and yield component of Yunmai 72 by multiple analysis methods. The results showed that Yunmai 72 had high-yield,good stability and wide adaptability. The yield was positively correlated with effective panicles and grains per panicle,but was not correlated with with thousand grain weight. The direct effect of effective panicles on yield was the main factor of high yield. Therefore,Yunmai 72 had a broad application prospect in the production of Yunnan Province.
