苜蓿(Medicago sativa)为豆科多年生草本植物,是世界上栽培最早、分布面积最广的一种优质牧草,素有“牧草之王”之称。目前,干旱与水资源短缺已成为世界农业和社会发展的制约因素,世界上有1/3以上的土地处于干旱和半干旱[1],亟需选育抗旱性强的苜蓿品种。研究旨在利用化学诱变处理苜蓿愈
Medicago sativa is a perennial herb of leguminosae. It is the earliest cultivated and most widely distributed pasture in the world, and is known as “King of Forage Grass”. At present, drought and water shortage have become the limiting factors of world agricultural and social development. More than a third of the world’s land is in arid and semi-arid regions [1], and it is urgent to breed drought-resistant alfalfa varieties. The aim of the study was to use chemical mutagenesis to treat alfalfa
