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
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.关键词
