摘要：

根据株高、产量、分蘖力从141份广东高州普通野生稻（Oryza rufipogon Griff.）材料中初选出20个生态型，分析其营养成分并对其作饲用稻的优劣进行综合排序。结果显示，GZW128的隶属值居前，粗蛋白产量最高，综合饲用价值好，可直接开发利用；GZW107的粗蛋白含量最高，为17.33% DM；GZW128的分蘖力和干物质量最高，分别为325个和68.33 g/株；GZW039灰分最少，为11.70% DM；GZW110粗纤维含量最低，为25.97% DM。上述野生稻均可作为后期全株饲料稻选育中相应性状改良的优质材料利用。

Abstract:

The plant height, tiller numbers and dry matter of common wild rice（Oryza rufipogon Griff.）drived from Gaozhou, Guangdong, were investigated and 20 types with good performance were selected for evaluating the nutrition quality. The results showed that GZW128 had higher membership values, the highest crude protein yield and better feeding value than other varieties, it could be directly utilized. GZW107, GZW128, GZW039 and GZW110 had some superior characteristics than others, which could be utilized as forage rice breeding materials in the future. GZW107 had the highest crude protein content. GZW128 had the strongest tillering ability and highest dry matter. GZW039 and GZW110 had the lowest crude ash content and crude fiber content respectively.
