| 摘 要： | 本研究详细阐述了早熟、高产、高糖、抗逆性强的甘蔗品种粤糖06-233的选育过程,并就其特征特性、蔗茎产量、蔗糖分、抗性等性状表现进行综合分析。以粤糖94-128为母本、桂糖93-159为父本配制杂交组合,历经8代农艺性状、糖分和产量相关性状的选择,育成了早熟、高产高糖、抗逆性强的甘蔗新品种粤糖06-233。通过国家区试和生产试验结果表明,粤糖06-233蔗茎产量达119 932.56 kg/hm 2,含糖量达18 145.79 kg/hm 2,该品种对甘蔗黑穗病具有较强的抗性。同时,利用去壁低渗法对粤糖06-233进行染色体数目与核型分析,结果表明,该品种的染色体主要由中部（m）及近中部（sm）着丝点染色体组成,染色体数为2n=88,核型公式K(2n)=88=82m+6sm。

| Abstract: | The objective of the paper was to introduce the breeding process of a new sugarcane cultivar,Yuetang 06-233,and its agronomic characters,stem yield,sucrose content,and disease and abiotic stress resistance.Yuetang 06-233,with early-maturing type,high stem yield,high sucrose content and good adversity resistance was successfully bred using Yuetang 94-128 and Yuetang 93-159 as female and male parents,after 8 generations selection based on agronomic,sugar,and yield traits.It exhibited high sugar yield and maximum stem yield at 18145.79 kg/hm^2 and 119932.56 kg/hm^2 in the national regional and production test,respectively,and it was highly resistant to Smut.Meanwhile,the chromosome number and karyotype of Yuetang 06-233 was studied by shedding cell wall and dialysis methods.The results showed that the chromosomes of the cultivar mainly was metacentric or submetacentric.The chromosome number of Yuetang 06-233 was 88,the karyotype formula was K(2n)=88=82m+6sm. |
