摘要
Abstract
Eight cultivars of sweet maize (Zea mays var. rugosa), which attended Guangdong provincial supersweet maize regional experiment in autumn cropping season in 1999, were evaluated by using the relation degree of grey system theory. They were analyzed from 17 traits including high-yielding, early-maturing, good-quality, plant height and green ear morphological characters. The comprehensive evaluation results showed that Supersweet 711 ranked first, which gave high yield, having strong stems and big green ears; Suitian 2ranked second, having traits of early maturing, good quality and a appropriate plant height with medium ear height. The unweighted relation degree of other tested varieties ranked in descending order being Jingfeng 3, Jinyin 2, Yuetian 3, Supersweet 28, Suitian 1 and Yuetian 2. The weighted relation degree was in the order: Supersweet 711＞Jinfeng 3＞Suitian 2＞Yuetian 3＞Supersweet 28＞Yuetian 2＞Jinyin 2＞Suitian 1.关键词
