Comparative study on quality traits of different Leymus chinensis varieties
To clarify the comprehensive performance of quality traits in different Leymus chinensis varieties and to explore excellent genetic sources of Leymus chinensis,the experiment selected 10 varieties of Leymus chinensis,arranged in random blocks,and used methods such as direct ashing and near-infrared spectroscopy to measure and analyze 22 quality indicators of the 10 Leymus chinensis varieties.The results of data clustering and factor analysis show that the 22 quality traits can be divided into two categories:Nutritional value indicators and morphological construction indicators.Variety YC01 has a prominent advantage in nutritional value traits,varieties YC06 and YC08 have achieved a good balance between nutritional value traits and morphological construction traits,with YC06 having a superior feeding value and can be considered as high-quality forage.The study indicates that the coordination and unity between nutritional value traits and morphological construction traits are the basic criteria for the selection of high-quality Leymus chinensis varieties,and can be used as superior trait gene sources for innovation and utilization.
