| 摘 要： | 以扁穗牛鞭草(Hemarthda compressa)品种重高为对照,从产草量、生长速度、分蘖数等7个性状方面,用逼近理想解的排序法(DTOPSIS)评价了11份扁穗牛鞭草无性系材料.结果表明,在该地区试种的7个无性系材料中.H002居第一位.H047、2003-6分别列第二、第三位,它们具有较好的丰产性和优质性.适于推广应用.研究结果还说明DTOPSIS法与常规产量分析结果基本一致,但比单用产量因素分析更加合理.并对DTOPSIS法在扁穗牛鞭草无性系材料综合评价中的有关问题进行了探讨.

| Abstract: | Eleven whipgrass(Hemarthria compressa) clones and control variety Chonggao were evaluated by using the method of DTOPSIS. Seven characters such as herbage yield, growth rates, total tiller number, etc were analyzed. The synthetically results showed that H002 was the best clone and H047 was the second, followed by 2003-6, they were all owned the high yield and good quality in certain degree. The results also showed that DTOPSIS was more suitable for judging whipgrass clones than the yield production analysis... |
