| 摘 要： | 从国家甘蔗种质资源圃内宿根六年的566份国内种质中筛选出134份田间综合性状表现较好的种质进行产量检测分析,结果表明:公顷产量在120t及以上种质有58个,占总数的43.28%;公顷产量在90～120t之间的种质有43个,占总数的32.09%;公顷产量在90t以下的种质有33个,占总数的24.63%;其中公顷产量在120t及以上的种质可做为高产强宿根亲本进行杂交或回交利用,从而达到甘蔗产量遗传改良的目的。

| Abstract: | One hundred and thirty-four sugarcane cuhivars were selected from 566 varieties in national sugarcane germplasm nurse based on the representation in the sixth year ratoon. The result showed that the yield of over 120 tons per hectare was 58 cuhivars germplasm, accounted for 43.28% of the total; 43 cuhivars were the middle germplasm, and yield was 90-120 tons per hectare, accounted for 32.09% of the total; 33 cuhivars were the low yield germplasm, and yield of 90-120 tons per hectare, accounted for 24.63% of the total. The germplasm of the yield of over 120 tons per hectare may be used as the parental or backcrossing materials. |
