用多元回归分析方法对不同基因型甘蔗伸长盛期+1叶的10个生化性状进行筛选,初步找出其中影响甘蔗产量、茎长、茎径、单茎重、有效茎数、蔗糖分和田间锤度等经济性状的主要生化因素。建立了根据伸长盛期+1叶生化性状来预测甘蔗经济性状的多元回归模型。分析结果表明,根据伸长盛期不同基因型甘蔗叶片的生化性状来预测各种经济性状的表现是有可能的。
Multiple regression analysis was used to screen 10 biochemical traits of + 1 leaf in different genotypes of sugarcane elongation stage. The results showed that the effects of yield, stem length, stem diameter, single stem weight, number of effective stems, sucrose and Field Brix and other economic traits of the main biochemical factors. A multivariate regression model was established to predict the economic traits of sugarcane according to the biochemical characters of the + The results showed that it is possible to predict the performance of various economic traits according to the biochemical traits of different genotypes of sugarcane leaves during the elongation stage.
