以广西甘蔗研究所鉴定圃材料为调查对象,研究分析了不同甘蔗亲本、家系及组合的开花习性,结果表明:在调查的308个组合1653个无性系材料中,出现开花的组合高达41.6%,开花无性系个体占无性系总数的17.4%,其中杂交后代中无性系开花数较多的母本有桂糖96-167、湛蔗74-141、湛蔗92-126、Roc11、Roc22、粤糖85-177、Roc23、Roc10、Roc24、粤糖91-976、Roc1、Roc20、CP81-1254;父本有桂糖00-122、CP84-1198、粤糖85-177、桂糖92-66、粤糖96-86、粤糖91-976、Roc16、桂糖73-167、粤糖93-159、Roc23、Roc22;组合有桂糖00-122×粤糖91-976、桂糖96-167×桂糖92-66、粤糖91-976×桂糖00-122、湛蔗92-126×CP72-2086、湛蔗74-141×CP84-1198、Roc26×粤糖96-86。
Based on the identification materials of Guangxi Sugarcane Research Institute, the flowering habits of different sugarcane parents, families and combinations were studied. The results showed that 41.6% of flowering combinations were found in the 308 combinations of 1653 clones, Clonal flowering clones accounted for 17.4% of the total number of clones, of which the progeny of hybrids more clonal flowering female parent Gui sugar 96-167, Zhan sugarcane 74-141, Zhan sugarcane 92-126, Roc11, Roc22, Guangdong sugar 85-177, Roc23, Roc10, Roc24, Cantalose 91-976, Roc1, Roc20, CP81-1254; the male parent has Gui sugar 00-122, CP84-1198, Cantalose 85-177, Guitang 92-66, Yue Sugar 96-86, candida 91-976, Roc16, guanose 73-167, candida 93-159, Roc23, Roc22; a combination of Gui sugar 00-122 × Yugu sugar 91-976, Gui sugar 96-167 × Gui Sugar 92-66, Sugar 91-976 × Gui Sugar 00-122, Sugar Sugars 92-126 × CP72-2086, Sugar Sugars 74-141 × CP84-1198, Roc26 × Glucose 96-86.
