摘要
在西宁地区，对６３２个燕麦品种的性状进行了研究。结果表明，品种间的性状差异很大，不同品种各性状最大与最小值的范围为：生育期７５～１３８ｄ，千粒重１３．２～５８．３ｇ，茎粗０．２５～０．７６ｃｍ，株高７４．２～２１０．０ｃｍ，单株粒重１．５～１４．９ｇ，秸秆产量３０３０～１４９１０ｋｇ／ｈｍ２，籽实产量１５００～５９２５ｋｇ／ｈｍ２；粒色有白、黄、褐、棕、黑等；株高、生育期和产量三者之间呈正相关关系。
? Character difference of 632 oats varieties was studied in Xining region. The results showed that changes of their character differences was great. The range between maximum and minimum of different varieties was growing period 75～138 d, 1 000seed weight 13.2～58.3 g, stemdiameter 0.25～0.76 cm, plant height 74.2～210.0 cm, seed weight of singleplant 1.5～14.9 g, straw yield 3 030～14 910 kg/hm2, seed yield 1 500～5 925 kg/hm2. Seed colour had white, yellow,drab, brown and black. There was positive relationship between plantheight, growing period and yield.
