Yield trait comparison of twenty two Alfalfa cultivars

摘要

Alfalfa is a quality perennial legume pasture with deeply distributing roots and commonly known as the king of pastures.Now most of the alfalfa cultivars that are planted in northwest China are poorly resistant to pests and disease and have low yields so that they are compromised in their extension and adoption in production.Therefore, it is imperative to introduce high‐quality and highly resistant alfalfa cultivars for crop production restructuring and animal husbandry development in arid and semi‐arid regions of Northwest China.
