本文分析了短蔓资源 1A5 33和商用品种“安农 2号”与“状元”的株型性状 ,结果表明 :1A5 33的节间长度、叶柄长度、蔓粗和柄蔓夹角均小于 2个商用品种 ,尤其是节间长度远远小于 2个商用品种 ,说明这些性状 ,尤其是节间长度性状有助于甜瓜株型改良。但 1A5 33的叶面积和单株产量低于商用品种 ,说明这 2个性状较差 ,亟待育种家改良
The results showed that the internode length, petiole length, vine length and stem axis of 1A5 33 were both less than 2 Commercial varieties, especially internode length is far less than 2 commercial varieties, indicating that these traits, especially internode length traits help melon plant type improvement. However, the leaf area and yield of 1A533 were lower than those of commercial varieties, which indicated that the two traits were poor.
