对新近配制的、以桂糖系列亲本为主的24个甘蔗杂交组合,采用模糊综合评判法进行了综合评价,结果表明15个杂交组合被评判为较优组合,9个组合被评判为一般组合。较优组合中桂糖92-66×云蔗89-159、桂糖03-1403×桂糖93-102、桂糖04-2603×CP84-1198、桂糖05-3445×桂糖03-2309、桂糖02-901×ROC10、ROC22×CP06-3458的锤度优集隶属度在0.500以上,表明从这些组合中较易筛选到农艺性状较好且糖分较高的后代。
A total of 24 newly-constructed crosses of sugarcane with guiose-based parents were evaluated by fuzzy comprehensive evaluation. The results showed that 15 crosses were judged as optimal combinations and 9 combinations were judged as general combinations . In the optimal combination, 92-66 × sugarcane 89-159, guanose 03-1403 × guanose 93-102, guanose 04-2603 × CP84-1198, guanose 05-3445 × guanose 03-2309, The goodness-of-bite membership values of 02-901 × ROC10 and ROC22 × CP06-3458 were higher than 0.500, indicating that the offspring with better agronomic characters and higher sugar content could be screened easily from these combinations.
