多年生小麦族种，包括一些世界上温带地区很有价值的牧草。此外，它们是改良栽培禾本科作物的抗性和其它性状的广泛杂交计划的基因资源。认真的育种尝试主要在冰草属，新麦草属，类麦属，赖草属，披碱草属和拟鹅观草属。几个改良品种的发放表明，扁穗冰草已在育种方案中受到很大的重视。通过育种，俄罗斯野麦Ｐｓａｔｈｙｒｏｓｔａｃｈｙｓｊｕｎｃｅａ（Ｆｉｓｈ）Ｎｅｖｓｋ的草丛建植长势已实质性提高，中间冰草与类麦改良饲料品质与抗性的选择有效。多年生小麦族中，种间杂交是个有前途的育种方法。最近发放的品种“Ｈｙｃｒｅｓｔ”和“ＮｅｗＨｙ”是通过种间杂交方案的著名实例。“Ｈｙｃｒｅｓｔ”来自诱导四倍体冰草与天然四倍体沙生冰草之间的杂种。“ＮｅｗＨｙ”的系谱是速生匍匐冰草与Ｅｌｙｒｉｇｉａｒｅｐｅｎｓ，兰丛冰草，Ｐ．ｓｐｉｃａｔａ之间的杂种。报道了诱导双单倍体的遗传进展。通过扩大植物 Perennial wheat species, including some of the world’s most valuable temperate grass. In addition, they are genetic resources for extensive hybridization programs that improve the resistance and other traits of cultivated grasses. Serious breeding attempts mainly in the genus Agropyron, New wheat grass genus, Leymus, Leymus, Elymus and the Aconitum. The issuance of several improved varieties shows that the plant has received great attention in breeding programs. Through breeding, the growth of grass in Russian Psathyrostachysjuncea (Fish) Nevsk has been substantially improved, and the choice of improved quality and resistance of midgut and ryegrass is effective. Of the perennial families of wheat, interspecific hybridization is a promising breeding method. The recently released varieties “Hycrest” and “NewHy” are famous examples of cross-species crossing programs. “Hycrest” comes from a hybrid that induces tetraploid toad and natural tetraploid toadstool. The pedigree of “NewHy” is the fast-growing grass with Elyrigiarepens, bluegrass, P. Hybrid between spicata. The genetic advances that induce double haploids have been reported. By expanding the plant
