摘要
对七个甘蔗基因型伸长盛期的株型性状表现以及它们与产量、品质性状的关系进行分析。研究结果表明：叶长是造成叶片披垂的主导因子，选择叶片宽大、平展、不披垂，比叶重、松散度、分蘖性适中的基因型，对后期产量、品质有较大的促进作用。
The performance of morphological characters in the great elongation stage and their effects on yield and quality characters were studied on seven sugarcane genotypes. The results showed that the length of leaves was the main factor to make leaves droop. If we select some sugarcane genotypes which have wide and flat leaves but not droop, and have suitable specific leaf weight, loose degree and tillering habit, It would promote the yield and quality in later stage.
