摘要:

黑麦草属(Lolium L.)与羊茅属(Festuca L.)是世界范围内重要的禾本科牧草和草坪草。黑麦草与羊茅杂交能综合黑麦草优良营养品质与羊茅抗逆性强的优点,可培育出优质抗逆的黑麦草羊茅杂种。同时黑麦草羊茅杂种是研究禾本科牧草遗传机制的优质试材,倍受世界各国育种工作者关注。本文总结了黑麦草羊茅杂种高产、优质、抗性强的优势;分析了杂种染色体配型特点;重点介绍了通过基因渗入、雄核发育和转基因手段改良牧草的方法;对黑麦草羊茅杂种基因组原位杂交、分子标记和遗传图谱建立、数量性状位点分析等分子遗传学的最新研究进展进行了综述。

Abstract:

Intergeneric hybrids (Festulolium) between Lolium and Festuca species were being increasingly used worldwide as forage grasses, which combined yield performance of Lolium (L. multiflorum Lam. and L. perenne L.) and tolerance against abiotic stress of Festuca (F. pratensis Huds. and F. arundinacea Schreb.). Festulolium was being used to provide the grass breeders with more options to create novel germplasms. In addition, the complex of species was an unique material to investigate the genetic mechanism of forage plants. The yield, quality, resistance and chromosome characteristics of the hybrids were analyzed, and the improvement of the grasses using gene introgression, androgenesis and genetic modification methods was introduced. The latest advance in GISH, genetic map construction and QTL of Festulolium hybrids were described here.
