不同红三叶种质资源的农艺性状比较研究

摘要

The agronomic characteristics of 10 red clover germplasm resources were studied for breeding of good varieties ofTrifolium pretenseL.. The results showed that the germination rate and germination index of variety 06p-2484 was the highest. The germination rate was 84.0% and germination index was 72.3%. The variety of 06p-2426 had the longest growth period and the shortest absolute height. The leaves of 06p-2426 variety were the longest and the widest and the stem was the thinest. So the variety of 06p-2426 red clover was a kind of excellent resource for appreciation and lawn. The absolute height of the 06p-2134 variety was the highest, but the lowest of the natural height,therefore,it had strong creeping characteristic;The Trifolium pretense L. varieties of the 06p-2426 and the 06p-2134 had a good application prospect.%为了选育优良的红三叶品种，对10份红三叶种质资源的农艺性状进行比较。结果表明：06p-2484品种发芽率和发芽指数最高，分别为84．0％和72．3％；06p-2426品种生育期较长、绝对高度最矮、小叶长度和宽度均最大、茎秆最细，是一种观赏性极好的坪用型红三叶资源；06p-2134品种绝对高度最高，而自然高度最矮，说明其匍匐性较强；06p-2426品种和06p-2134品种均有较好的应用前景。
