老芒麦种质资源在青海环湖地区农艺性状的比较

Study on the Agronomic Character of Elymus sibiricus Germplasm Resources in the Area Around Qinghai Lake

对5份老芒麦野生材料从生育期、株高、叶片大小、茎叶比、分蘖数、种子产量等主要农艺性状方面进行了比较研究。结果表明,在5份供试材料中,采自新疆乌鲁木齐甘沟的老芒麦(E2)具有产草和种子产量高的优势,农艺性状和生产性能最为突出,生产潜力大,可作为培育高产栽培品种的种质材料,也是改良某些品种的理想的亲本材料。

Five wild materials of Elymus sibiricus were studied in their plant height, leaf length and width, ratio of stem and leaf, tillers, seed yield and so on. The results showed that Elymus sibiricus collected from Gange meadow of Urumqi in Xinjiang was superior to others in grass yield and seed yield, Its agronomic character and productivity performed very well. It was the best germplasm resource and can be used as parental material to improve some cultivar in alpine region.
