甘蔗新品种比较研究(英文)

Comparison of New Varieties of Sugarcane in China

为了筛选适合我国主产蔗区的优良品种,为推广提供依据,特对全国9个甘蔗新品种进行研究,以Roc22号作对照。研究结果表明:萌芽率较高的品种是粤糖55、福农15、桂糖02-901、粤糖00-236,分蘖率高的有粤糖55、粤糖00-236,蔗茎产量高于对照的有粤糖55、桂糖97-69、粤糖00-236和福农15等4个品种,蔗糖分较高的是桂糖02-901和云蔗99-91,耐寒性较强的是云蔗99-91、云蔗03-422、粤糖55、粤糖00-236等4个品种,公顷含糖量较高的是粤糖55、福农15、粤糖00-236、桂糖97-69。综合性状表现较好的是粤糖00-236和福农15号,可作为优良品种在主产蔗区推广。

This study aims to provide information on the dissemination potentials of some sugarcane varieties in the main sugarcane producing regions of China through screening some newly bred sugarcane varieties. Nine sugarcane varieties were chosen to study their agronomy and yield potentials in comparison with the control vari- ety Roc22. The agronomic characters studied were the sprouting rate, tillering rate, cane production, sugar content, chilling tolerance and sugar production per unit area. Results showed, compared with the control, YT55, Funong15, GT02-901 and YT00- 236 had higher sprouting rate. YT55 and YT00-236 showed higher tillering rate than Roc22. Four varieties, YT55, GT97-69, YT00-236 and Funong15, gave higher cane production than the control. GT02-901 and Y799-21 had the highest sugar content and YT55, Funong15, YT00-236 and GT97-69 produced more sugar per hectare. YZ99-91, YZ03-422, YT55 and YT00-236 showed improved chilling tolerance. It was concluded that YT00-236 and Funong15 are the top two sugarcane varieties with comprehensive advantages and could be widely disseminated through the main sugarcane producing regions in China.
