摘　　要：我国西南大部分地区是发展多年生饲草的优势区域,同时也是薏苡(Coixlacryma-jobi)的起源地,种质资源丰富,遗传变异类型多,其中的野生薏苡具有品质优、抗性好、产量高和多年生等优点,是一种新型的饲草种质资源。近几年,利用野生薏苡选育饲草品种和相应的动物饲喂研究结果也均表明野生薏苡是一种优秀的饲草。本文从我国西南地区发展多年生饲草的前景、植物近缘野生种在我国饲草选育中的应用、野生薏苡作为饲草种质资源的优良特性和育种应用几个方面进行了阐述,并对多年生饲用薏苡应用存在的问题和后续品种选育进行了探讨。Most regions in southwest China experience a subtropical humid climate, which is advantageous for growing perennial forage grass. As a native plant species of China, Coix is a rich germplasm resource with various ecotypes, especially wild Coix, which has a high nutritive value and biomass, excellent abiotic stress resistance, and perennial habit. It can be used as a promising forage germplasm. Here, we expound the prospect of developing perennial forage grass in southwest China, application of plant wild relatives in grass breeding, and advantage of wild Coix as forage germplasm, and its breeding. Furthermore, we propose future research directions in perennial forage Coix breeding and production.
