海南主要芒果品种的模糊聚类分析

Fuzzy Cluster Analysis of Hainan Main Mango Cultivars According to Leaves' Characters

根据芒果的叶片性状变量(包括叶形、叶长、叶宽、嫩叶颜色和叶缘等5个方面),对海南22个芒果主栽品种运用模糊聚类的方法进行分析。结果表明:第1类芒果品种包括吕宋、台农1号、白玉、椰香、青皮、紫花、粤西1号、桂香芒、广西红芒、三年芒、龙眼香芒、桂热10号共12种;第2类芒果品种包括白象牙、海南土芒、海豹、金煌、黄象牙芒、扁桃芒共6种;第3类芒果品种包括云南小芒、红象牙、兴热1号共3种;第4类芒果品种包括黄玉芒1种。这与前人用其它方法分类的结果类似。分类结果可应用于芒果品种的识别与选育。

With the aid of Fuzzy Cluster Analysis, 22 Hainan main mango cultivars were divided into four classes according to their leaf characters including leaf shape, leaf length, leaf width, color of young leaf and leaf margin. The results were similar to those obtained by traditional methods. A reasonable and feasible mathematic method is provided for studying the classification of tropical agricultural species.
