摘要
桂糖51号(试验代号:桂糖06-1023)是广西壮族自治区农业科学院甘蔗研究所以ROC20为母本、崖城71-374为父本进行有性杂交,采用"五圃制"常规育种技术选育而成的甘蔗新品种。多年试验结果表明,该品种出苗好、宿根发株多、分蘖力强,有效茎数多,中大茎,具有早熟、高糖、高产稳产、宿根性好、易脱叶、抗倒性强、适应性广等诸多优良特性。在2014—2015年广西区域试验中,桂糖51号2年新植1年宿根平均蔗茎产量(102.66 t/hm2)比对照ROC22增产2.49%,平均蔗糖产量(14.46 t/hm2)比对照增产5.17%;其中宿根蔗优势明显,蔗茎产量(108.74 t/hm2)比对照增产12.25%,蔗糖产量(15.59 t/hm2)比对照增产17.67%;平均蔗糖分(14.09%)比对照高0.36%(绝对值)。桂糖51号适宜在土壤疏松,中等以上肥力的蔗区种植。
Using ROC20 as female parent and Yacheng 71-374 as male parent, the new variety Guitang 51 (test code: Guitang 06-1023 )was bred systematically through sexual hybridization and "Five-nursery System" breeding procedure by Guangxi Sugarcane Research Institute. Multiple -year results showed that Guitang 51 had the following good characteristics: high emergence rate, high ratooning rate, strong tillering ability, mid-to large stem; early maturity, high sugar content, high and stable yield, good ratoon ability, easy defoliating leaves at maturity, resistance to lodging and wide adaptability. In Guangxi regional trials from 2014 to 2015, the average yields of cane and sugar were 102.66 and 14.46 t/ha, compared with control variety ( ROC22), which were increased by 2.49% and 5.17% , respectively; Guitang 51 had obvious advantages over ROC22 in the ratoon seedling especially, it's cane yield and sugar yield reached 108.74 t/ha and 15.59 t/ha, which were increased by 12.25% and 17.67% compared with control variety ( ROC22), respectively; the sucrose content was 14.09% higher 0.36% (absolute value) than that of the control variety. Guitang 51 is suitable for planting in sugarcane area with loose soil and medium or above fertility.
