Abstract:

在热带北缘蔗区对斑茅蔗(其原始亲本：Badila × 斑茅)回交入选的优异品系30份株系和品种新台糖22号(ROC22)进行田间比较试验。结果显示，Badila斑茅优异品系群体的单位面积有效茎数比对照品种新台糖22号(ROC22)增长1.1%，表现出较明显的优势；占10.3%的品系的茎锤度、24.1%的品系的株高和31.0%的品系的公顷产量分别高于对照品种；9份品系的农艺经济综合性比较优良，其单位面积有效茎数及产量均大幅度超越新台糖22号。
Field comparison test was applied using cultivar ROC22 and 30 copies of selections strain first backcross generation of the hybrid Badila × Hainan Saccharum arundinaceum Retz. in the cane-growing region on the northern rim of the tropics. The results showed that the effective number of stems in unit area of strain increased 1% than the control cultivar ROC22, showing significant advantage. Stem brix accounted for 10.3% of the strains, plant height for 24.1%, and yield per hm² for 31.0% were higher than those of the control strains. The agronomic and economic traits of nine of the strains are relatively fine, the effective number of stems and yield in unit area of which are both significantly better than ROC22.
