冬青稞品种‘云青602’产量及适应性评价
Yield and Adaptability Evaluation of ‘Yunqing 602’ Winter Hulless Barley Variety
【摘要】 本研究旨在探究冬青稞品种‘云青602’在云南省不同生态区的适应性,以及其营养品质与农艺性状的差异,为此,在云南省青稞种植面积较大的7个试点开展试验,并对产量及品质等相关性状进行分析。研究结果表明,不同生态点‘云青602’的产量及构成因素的变异系数范围在0.00~0.19之间,属于变异程度较小;相比之下,不同生态点对‘云青602’的产量和有效穗影响较大,其次是穗粒数,对千粒重影响较小;成穗率都在50%以上;生育期和9个品质指标除气温较低的迪庆之外,在各生态点表现基本一致;营养品质和农艺性状在各试验点有所差别。基于此,可根据具体用途选择适宜的种植区域。综上所述,青稞品种‘云青602’具有较高的丰产性和稳产性,在7个生态点均展现出较强的适应性,适宜在云南省大面积推广种植。
【Abstract】 To understand the adaptability of winter hulless barley variety ’Yunqing 602’ in different ecological regions of Yunnan Province, as well as the differences in nutritional quality and agronomic traits, a trial was conducted at seven test sites in areas with extensive hulless barley cultivation in Yunnan Province, to analyze yield-related characteristics and quality parameters. The results showed that the coefficient of variation for yield and its components of ’Yunqing 602’ across different ecological sites ranged from 0.00 to 0.19, indicating relatively low variation. In comparison, different ecological environments had greater impacts on yield and effective panicles of ’Yunqing 602’, followed by grains per panicle, while showing minimal influence on 1000-grain weight. The spike formation rate exceeded 50% at all sites. Except for Diqing where lower temperatures occurred, the growth duration and nine quality indicators remained essentially consistent across ecological regions. Nutritional quality parameters and agronomic traits varied across test sites, suggesting that appropriate cultivation areas could be selected based on specific intended uses. In conclusion, ’Yunqing 602’ demonstrates both high yield potential and stable productivity, exhibiting strong adaptability across all seven ecological sites.It is therefore suitable for large-scale cultivation throughout the province.
