为直观地对甘蔗杂交组合进行筛选及评价,选择对甘蔗杂交组合优劣影响最大的四个因素(锤度、株高、茎径、有效茎),以2009年广西甘蔗研究所实生苗的24个亲本杂交组合为研究对象,采用模糊综合评判方法,研究锤度、株高、茎径、有效茎的相互作用对24个甘蔗杂交组合的影响,从中筛选出优的甘蔗杂交组合1个(ROC24×粤糖91-976),较优的甘蔗杂交组合10个(ROC1×ROC22、ROC1×桂糖96-211、桂糖92-66×湛蔗92-126、粤糖91-976×ROC1、桂糖92-66×福农91-4621、桂糖94-119×CP74-383、粤糖89-113×HoCP93-750、ROC10×崖城94-46、崖城99-31×ROC22、桂糖92-66×桂糖00-245),这些组合可用到今后的育种实践。
In order to visually select and evaluate the crosses of sugarcane, the four factors (brix, plant height, stem diameter and effective stem) which have the greatest influence on the pros and cons of the crosses of sugarcane were selected. Based on 24 The effects of brix, plant height, stem diameter and effective stalk interaction on the 24 combinations of sugarcane were studied by using the fuzzy comprehensive evaluation method. One of the crosses (ROC24 × Guangdong sugar 91-976), and 10 superior combinations of sugarcane (ROC1 × ROC22, ROC1 × guanose 96-211, 92-66 × sugarcane 92-126, 91-976 × ROC1, Sugar 92-66 × Fuonan 91-4621, Guitang 94-119 × CP74-383, Cantalose 89-113 × HoCP93-750, ROC10 × Yacheng 94-46, Yacheng 99-31 × ROC22, Guitang 92 -66 × guanose 00-245), these combinations can be used for future breeding practice.
