黄花苜蓿种质的优良特性与利用价值

CHARACTERISTICS AND UTILIZING VALUES ON THE GERMPLASM OF MEDICAGO FALCATA

黄花苜蓿是我国北方草原的优良牧草,具有许多紫花苜蓿不具备的优良特性,是苜蓿抗性育种的重要基因库。本文介绍了黄花苜蓿种质资源的分布和抗寒、抗旱、耐盐、耐牧等优良特性,并对其饲用价值、遗传育种价值和生态价值进行了评述,为筛选苜蓿抗性育种的优异种质材料提供参考依据。

Medieago faleata is a kind herbage species in the grassland of northern China. It has many excellent characteristics which Medieago sativa does not possess, and therefore it is an important gene pool for alfalfa breeding. In this paper, the natural distribution, characteristics on winter hardiness, drought resistance, salt resistance and grazing tolerance of Medieago faleata were reviewed, and the some vales such as feeding, genetic breeding, ecological values were discussed. The purpose of the study is to select excellent germplasm for alfalfa breeding on stress resistance.
